Definitions

  • the present invention is generally related to anti-inflammatory compositions containing a synergistic combination of two or more substances. More specifically, the present invention relates to pharmaceutical, nutraceutical, cosmetic or veterinary compositions comprising a synergistic combination of a) at least one anti-inflammatory cannabinoid and b) Glycyrrhiza plant material or its extracts or isolates or bio active ingredients thereof, such as glycyrrhizic acid or its aglycon or salts or derivatives.
  • the compositions of the present invention may be used for treating inflammatory, immune and auto-immune diseases.
  • Cannabis commonly known as marijuana, is a product of Cannabis species such as Cannabis sativa, Cannabis Indica and Cannabis Hemp plants. These plant species generally contain a very large number of active compounds, including those that are collectively referred to as cannabinoids. Cannabis or Marijuana has been found effective in alleviating symptoms of many auto-immune and inflammatory diseases such as multiple sclerosis, colitis, rrheumatoid arthritis, and cannabinoids were demonstrated to have anti inflammatory activity in-vitro and in-vivo animal models and humans.
  • Volatile oil products of the plant also have biological activity.
  • the geranylated flavone cannflavin A is 30 times more potent than aspirin as an inhibitor of prostaglandin E 2 .
  • Some volatile Cannabis terpenes for example humulene and caryophyllene, are potent anti-inflammatory agents.
  • Liquorice or licorice which is an extract of Glycyrrhiza species such as glabra is one of the most used plants in food medicine and cosmetics, and belong to the Genus Glycyrrhiza, family Leguminosae; many species are used to obtain licorice, the chief commercial source being the cultivated G. glabra.
  • Licorice is a chewy, aromatic black substance made by evaporation from the juice of a root and used as a sweet and in medicine.
  • the extract from the Glycyrrhiza glabra plant contains glycyrrhizic acid (GZA).
  • GZA is made of one molecule of glycyrrhetic acid and two molecules of glucuronic acid.
  • the extracts from the root of the plant can also be referred to as licorice, sweet root, and glycyrrhiza extract.
  • the product of glycyrrhetic acid is found in human urine whereas GZA is not. This shows that glycyrrhetic acid is absorbed and metabolized in the intestines in humans.
  • GZA is hydrolyzed to glycyrrhetic acid in the intestines by bacteria.
  • G. glabra has been used for medicinal purposes including the treatment of disorders of digestion and stomach inflammation. Some other medicinal uses include cough suppression, ulcer treatment, and use as a laxative. Also, salts of GZA can be used in many products as sweeteners and aromatizers. Licorice extract is often found in sweets and many candies, some drugs, and beverages like root beer. They can also be used in chewing gum, tobacco products and toothpaste. [0007] Laboratory studies done in Japan (where an injectable glycyrrhizin compound is used in people with chronic hepatitis C who do not respond to conventional treatment) suggest that glycyrrhizin may have some effect against hepatitis C. [0008] Topical licorice extract may improve skin rash symptoms, such as redness, swelling, and itching.
  • Some of the common medical benefits of licorice are: allergy relief, as demonstrated in various in vitro and in vivo studies which support the traditional use of Licorice ( Glycyrrhiza glabra) for allergies. Glycyrrhizin is attributed with relieving IgE- induced allergies (e.g. asthma). Licorice has also been used for its anti-oxidant, anti convulsant, anti-oxidant actions that also protected against neuron damage.
  • Licorice is traditionally used in tobacco products in order to reduce airway injury and may be formulated into cigarettes. Licorice -derived or related compounds have been tested for reduced coughing and treating airways inflammation.
  • Neuro-inflammation is considered as a factor or a cause of many neurological diseases and chronic pain disorders. There is a need to provide a better treatment for many neurological disorders and pain of neurological inflammatory origin that is currently not well treated and sometimes treated only by steroids, while acute and flair conditions are treated with mega doses of steroids that resulting in sever and irreversible and debilitating adverse effects.
  • Fibrosis is a result of injury and chronic inflammation, there is a need for an anti inflammatory medication that will alleviate chronic inflammation and will prevent fibrosis and be anti-fibrotic.
  • COX-2 cyclooxygenase-2
  • PGE2 prostaglandin E2
  • PGE 2 is generally considered to possess potent tumor-promoting activity. This inference is based on a substantial body of evidence obtained from rodent studies, as well as several decades of clinical research on the effects of NSAIDs on cancer risk. [0017] Chronic inflammation contributes to cancer development via multiple mechanisms.
  • the immunosuppressive environment in certain chronic inflammatory diseases and solid cancers is characterized by accumulation of proinflammatory mediators, infiltration of immune suppressor cells and activation of immune checkpoint pathways in effector T cells.
  • Many inflammatory diseases such as mucositis, gingivitis, conjunctivitis, otitis, skin ulcers and wounds, diabetic foot ulcers, are multifactorial, involving inflammation and infection that can be a mixture of bacterial, viral or fungal.
  • Such conditions are difficult to treat and there is a great need for an anti-inflammation medication that will be on the same time anti- infective and analgesic.
  • the present inventor has now unexpectedly found that a combination of a cannabinoid with licorice extract (or with isolates of said extract) possesses a synergistic anti-inflammatory effect that has the potential to provide effective treatment for many inflammatory diseases and provide a safer, yet highly effective, alternative to medication with steroids.

Description

ANTI-INFLAMMATORY SYNERGISTIC COMPOSITIONS COMPRISING CANNABINOIDS AND LICORICE
FIELD OF THE INVENTION
[0001] The present invention is generally related to anti-inflammatory compositions containing a synergistic combination of two or more substances. More specifically, the present invention relates to pharmaceutical, nutraceutical, cosmetic or veterinary compositions comprising a synergistic combination of a) at least one anti-inflammatory cannabinoid and b) Glycyrrhiza plant material or its extracts or isolates or bio active ingredients thereof, such as glycyrrhizic acid or its aglycon or salts or derivatives. The compositions of the present invention may be used for treating inflammatory, immune and auto-immune diseases.
BACKGROUND OF THE INVENTION
[0002] Cannabis, commonly known as marijuana, is a product of Cannabis species such as Cannabis sativa, Cannabis Indica and Cannabis Hemp plants. These plant species generally contain a very large number of active compounds, including those that are collectively referred to as cannabinoids. Cannabis or Marijuana has been found effective in alleviating symptoms of many auto-immune and inflammatory diseases such as multiple sclerosis, colitis, rrheumatoid arthritis, and cannabinoids were demonstrated to have anti inflammatory activity in-vitro and in-vivo animal models and humans.
[0003] Potent anti-inflammatory actions of a crude marijuana extract and of the non psychoactive Cannabis constituents, for example, cannabidiol (CBD), cannabidiolic acid (CBDA), tetrahydro cannabinolic acid (THCA), cannabinol, cannabigerol, cannabivarin, and cannabichromene has been demonstrated in many animal models such as in the carrageenan paw edema model of acute inflammation in rats. Tetra hydro cannabinol (THC) was also demonstrated to have anti-inflammatory activity in various in-vitro and animal models. Cannabinoids apparently act on inflammation through mechanisms different from those of agents such as nonsteroidal anti-inflammatory drugs (NSAIDs). As a class, the cannabinoids are generally free from the adverse effects associated with steroids and NSAIDs. Their clinical development thus provides a new approach to treatment of various diseases, including, for example, those characterized by acute and chronic inflammation and fibrosis.
[0004] Volatile oil products of the plant also have biological activity. The geranylated flavone cannflavin A, is 30 times more potent than aspirin as an inhibitor of prostaglandin E2. Some volatile Cannabis terpenes, for example humulene and caryophyllene, are potent anti-inflammatory agents. Liquorice or licorice which is an extract of Glycyrrhiza species such as glabra is one of the most used plants in food medicine and cosmetics, and belong to the Genus Glycyrrhiza, family Leguminosae; many species are used to obtain licorice, the chief commercial source being the cultivated G. glabra.
[0005] Licorice is a chewy, aromatic black substance made by evaporation from the juice of a root and used as a sweet and in medicine. The extract from the Glycyrrhiza glabra plant contains glycyrrhizic acid (GZA). GZA is made of one molecule of glycyrrhetic acid and two molecules of glucuronic acid. The extracts from the root of the plant can also be referred to as licorice, sweet root, and glycyrrhiza extract. When administered orally, the product of glycyrrhetic acid is found in human urine whereas GZA is not. This shows that glycyrrhetic acid is absorbed and metabolized in the intestines in humans. GZA is hydrolyzed to glycyrrhetic acid in the intestines by bacteria.
[0006] For thousands of years G. glabra has been used for medicinal purposes including the treatment of disorders of digestion and stomach inflammation. Some other medicinal uses include cough suppression, ulcer treatment, and use as a laxative. Also, salts of GZA can be used in many products as sweeteners and aromatizers. Licorice extract is often found in sweets and many candies, some drugs, and beverages like root beer. They can also be used in chewing gum, tobacco products and toothpaste. [0007] Laboratory studies done in Japan (where an injectable glycyrrhizin compound is used in people with chronic hepatitis C who do not respond to conventional treatment) suggest that glycyrrhizin may have some effect against hepatitis C. [0008] Topical licorice extract may improve skin rash symptoms, such as redness, swelling, and itching.
[0009] Some of the common medical benefits of licorice are: allergy relief, as demonstrated in various in vitro and in vivo studies which support the traditional use of Licorice ( Glycyrrhiza glabra) for allergies. Glycyrrhizin is attributed with relieving IgE- induced allergies (e.g. asthma). Licorice has also been used for its anti-oxidant, anti convulsant, anti-oxidant actions that also protected against neuron damage. It has also shown potential as a modulator of genotoxins and free radical scavenger; anti-inflammatory abilities, and in reducing nitric oxide synthase expression; treatment of oral mucositis post radiation and chemotherapy in cancer patients; inhibition of cancer cell proliferation; Conjunctivitis; protection against liver and kidney damage from acetaminophen in a dose dependent manner and neuroprotection.
[0010] Licorice is traditionally used in tobacco products in order to reduce airway injury and may be formulated into cigarettes. Licorice -derived or related compounds have been tested for reduced coughing and treating airways inflammation.
[0011] While many of the severe autoimmune and inflammatory diseases are well treated with steroids, these agents also possess many severe and dose-limiting unwanted side effects.
[0012] There is thus an unmet need for compositions and methods for the effective treatment of many autoimmune and inflammatory diseases and a need for an effective and safe non-steroidal anti-inflammatory medication.
[0013] Neuro-inflammation is considered as a factor or a cause of many neurological diseases and chronic pain disorders. There is a need to provide a better treatment for many neurological disorders and pain of neurological inflammatory origin that is currently not well treated and sometimes treated only by steroids, while acute and flair conditions are treated with mega doses of steroids that resulting in sever and irreversible and debilitating adverse effects. [0014] Fibrosis is a result of injury and chronic inflammation, there is a need for an anti inflammatory medication that will alleviate chronic inflammation and will prevent fibrosis and be anti-fibrotic.
[0015] It is widely accepted that cancer is associated with inflammation and alterations to cyclooxygenase-2 (COX-2) expression and the abundance of its enzymatic product prostaglandin E2 (PGE2) have key roles in influencing the development of colorectal cancer. Deregulation of the COX-2/PGE2 pathway appears to affect colorectal tumorigenesis via a number of distinct mechanisms: promoting tumor maintenance and progression, encouraging metastatic spread, and perhaps even participating in tumor initiation.
[0016] Within the context of cancer and inflammation, PGE2 is generally considered to possess potent tumor-promoting activity. This inference is based on a substantial body of evidence obtained from rodent studies, as well as several decades of clinical research on the effects of NSAIDs on cancer risk. [0017] Chronic inflammation contributes to cancer development via multiple mechanisms.
One potential mechanism is that chronic inflammation can generate an immunosuppressive microenvironment that allows advantages for tumor formation and progression. The immunosuppressive environment in certain chronic inflammatory diseases and solid cancers is characterized by accumulation of proinflammatory mediators, infiltration of immune suppressor cells and activation of immune checkpoint pathways in effector T cells. Many inflammatory diseases, such as mucositis, gingivitis, conjunctivitis, otitis, skin ulcers and wounds, diabetic foot ulcers, are multifactorial, involving inflammation and infection that can be a mixture of bacterial, viral or fungal. Such conditions are difficult to treat and there is a great need for an anti-inflammation medication that will be on the same time anti- infective and analgesic. SUMMARY OF THE INVENTION

DEFINITIONS
[0040] The term“cannabinoid” as used herein generally refers to one of a class of diverse chemical compounds that act on a cannabinoid receptor in cells that repress neurotransmitter release in the brain. The term“cannabinoid” as used herein further refers a chemical compound that acts on cannabinoid receptors or has a structure similar the stature of a compound acting on cannabinoid receptor in cells. Ligands for these receptor proteins include the endocannabinoids (produced naturally in the body by humans and animals), the Phyto cannabinoids (found in cannabis and some other plants), and synthetic cannabinoids (manufactured artificially).
[0041] The term “anti-inflammatory cannabinoid” is any cannabis plant material or synthetic equivalent, derivative or analogue (regardless of whether or not it interacts with cannabinoid receptors) that is derived from, or mimics the cannabinoids found in the cannabis plants and that has an anti-inflammatory effect. Such an anti-inflammatory effect is demonstrated by inhibiting or reducing the release of cytokines in macrophage cells that are in contact with an allergen such as LPS (lipopolysaccharide) that cause release of cytokines as part of the inflammation and pro-inflammatory activity or by inhibiting the cyclo-oxygenase enzymes. Anti-inflammatory cannabinoids reduce the amount of pro- inflammatory cytokines release, for example; TNF alpha, IL-l, IL-6, NO, PGE2 and or any of the about eighty (80) cytokines and the inflammation mediators and immune mediators known in the art and more specifically, pro-inflammatory cytokines or mediators.
[0042] The term "cannabis extract" as used herein refers to one or more plant extracts from the cannabis plant. A cannabis extract usually contains, in addition to one or more cannabinoids, one or more non-cannabinoid components which are co-extracted with the cannabinoids from the plant material. Their respective ranges in weight will vary according to the starting plant material and the extraction methodology used. Cannabinoid-containing plant extracts may be obtained by various means of extraction of cannabis plant material. Such means include but are not limited to: supercritical or subcritical extraction with C02, extraction with hot or cold gas and extraction with solvents.
[0043] The term licorice or liquorice extract as used herein refers to one or more Glycyrrhiza species plant extract from the Glycyrrhiza glabra plant and other species and to its extracts or its purified isolated molecules from the plant Glycyrrhiza glabra and its species and sub types and isolates and derivatives and combinations thereof.
[0044] The term“synergistic” as used herein is refers to the phenomenon wherein the cumulative pharmacological effect of two ingredients when used in combination is higher than the sum of the effect of each of them tested individually. The term“potentiating” as used herein refers to the phenomenon where the efficacy of an active ingredient is significantly enhanced when it is combined with a second ingredient, wherein said second ingredient itself does not demonstrate any efficacy in the same pharmacological test. In some cases of potentiation, not only is said second ingredient devoid of the pharmacological effect being measured, it may even cause an opposite effect, when assayed alone. An example of such a case would be as follows: ingredient A is anti-inflammatory; ingredient B is pro-inflammatory; when A and B are combined, said combination produces an anti-inflammatory effect that is greater than seen with A alone. In the context of the present invention, potentiation is regarded as a special case of synergism. Thus, the term ‘synergism’ (or synergistic, or the like), when used to define the properties of a composition of the present invention, also includes within its range of meaning the potentiation effect described immediately hereinabove.
The term“glycyrrhizanoids” as used herein is refers to active ingredients or active constituents or active isolates obtained from the plant glycyrrhiza species.
[0045] The term "about" as used herein refers to any value which lies within a range of ± 5% of original value. For example,“about 100” refers to“95 to 105”.
[0046] The term“pharmaceutical composition” as used herein has its conventional meaning and refers to a composition which is pharmaceutically acceptable. The term “pharmaceutically acceptable” as used herein has its conventional meaning and refers to compounds, material, compositions and/or dosage forms, which are, within the scope of sound medical judgment suitable for contact with the tissues of mammals, especially humans, without excessive toxicity, irritation, allergic response and other problem complications commensurate with a reasonable benefit/risk ratio. The term“excipient” as used herein has its conventional meaning and refers to a pharmaceutically acceptable ingredient, which is commonly used in the pharmaceutical technology for preparing a granulate, solid or liquid oral dosage formulation. The term "cosmetic composition" is intended to mean a substance or a preparation intended to be brought into contact with the various superficial parts of the body, in particular the epidermis, the body-hair and head- hair systems, the nails, the lips and the oral mucous membranes. The term“veterinary composition” encompasses the full range of compositions for internal administration and feeds and drinks which can be consumed by animals.
[0047] Unless otherwise stated, all ratios between different components of the compositions disclosed herein are weight ratios. [0048] The methods, uses, materials, and examples that will now be described are illustrative only and are not intended to be limiting; materials, uses and methods similar or equivalent to those described herein can be used in practice or testing of the invention. Other features and advantages of the invention will be apparent from the following figures, detailed description, and from the claims.

[0051] The present invention is based on the surprising finding that there is a synergistic or potentiating interaction between a) at least one anti-inflammatory cannabinoid and b) at least one licorice isolates or licorice extracts, with respect to the reduction or inhibition of the of pro-inflammatory cytokines and mediators. [0052] It has also been unexpectedly discovered that a composition comprising a combination of at a) least one anti-inflammatory cannabinoid and with b) at least one licorice isolate or extracts, reduces the secretion of pro-inflammatory cytokines in a macrophage cell line that was stimulated by means of pre-treated with lipopolysaccharides (LPS), in a synergistic or a potentiating manner, whereas the magnitude of inhibition of cytokine secretion is higher for the composition than the sum of the inhibition of cytokines release by the individual ingredients. In many cases, the efficacy of this anti-inflammatory effect of the composition is comparable to the effect obtained by the use of a steroidal or non-steroidal anti-inflammatory (NSAID) agent. In a particularly preferred embodiment of the invention, the at least one cannabinoid is selected from: Cannabidiol (CBD), Cannabidiol acid (CBDA), tetra hydro cannabinol or tetrahydrocannabinolic acid (THC) or (THCA), compounds which has been found to possess a strong anti-inflammatory activity as well as a broad range of other biological activities.

The types of plant material, plant parts and extraction methods to be used are all well known to the skilled artisan in this field. Extraction and processing may result in broad spectrum of cannabis molecules, cannabinoids, terpenes and other families of natural cannabis molecules or in a pure extract of cannabinoids or concentrated cannabinoid terpenes extract. Cannabis or marijuana extract may be further decarboxylated, winterized and/or purified, for example by distillation, as known in the art. [0072] In certain embodiments, the composition comprises an essential oil or terpenes or combinations thereof. In certain embodiments, the terpene is a natural terpene found in a Cannabis plant. In certain embodiments, the terpene is a synthetic terpene. In certain embodiments, the terpene is a mixture of natural terpenes. In certain embodiments, the terpene is a mixture of synthetic terpenes. In certain embodiments, the terpene is a mixture of natural and synthetic terpenes. In certain embodiment the terpene is a cannabis anti inflammatory agent.
[0073] In certain embodiments, the terpene is selected from the group consisting of bisabolol, borneol, caryophyllene, carene, camphene, cineol, citronella, eucalyptol, geraniol, guaiol, humulene, isopropyltoluene, isopulegol, linalool, limonene, methyl salicylate, menthol, myrcene, nerolidol, ocimene, pinene, phytol, pulegone, terpinene, terpinolene, thymol, salts thereof, derivatives thereof and mixtures thereof. Each possibility represents a separate embodiment of the invention.
[0074] In certain embodiments the terpene is a cannabis plant terpene, or a terpene derived from a non-cannabis plant material or a synthetic terpene. In certain embodiment the terpene is a taste modifier or smell modifier agent, a food grade or pharmaceutical grade, a solubilizer or solvent and an excipient in the formulation.
[0075] About 120 distinct terpenes are produced by the genus Cannabis, with the relative concentrations of the individual terpenes varying greatly among the 700 distinct strains currently in cultivation. Aside from taste and smell differences between varieties, this helps contribute to the broad diversity of potential medical applications of Cannabis.
[0076] In certain embodiments of the pharmaceutical composition, the natural cannabinoid is derived or isolated from an extract of a Cannabis plant. In certain embodiments of the composition, the natural terpene is derived or isolated from an extract of a Cannabis plant. [0077] In certain embodiments, a terpene or the mixture of terpenes solubilized with a cannabinoid or a mixture of cannabinoid. Each possibility represents a separate embodiment of the invention.
[0078] These optional components can be used either alone or in combination with other ingredients to improve the chemical and physical properties of the cannabinoid isolate or extract or the drug delivery systems and the cannabinoids or the terpenes chemical stability and shelf life.
[0079] The present invention further provides, in an aspect, a dosage form, comprising or consisting of any one of the compositions described above.
[0080] The term "dosage form" denotes any form of the solid formulation that contains an amount of a cannabinoid or of a mixture of cannabinoids sufficient to achieve at least a partial therapeutic effect with a single administration. [0081] In certain embodiments, the dosage form is an oral dosage form. In certain embodiments, the dosage form is a rectal dosage form. In certain embodiments, the dosage form is a nasal dosage form. In certain embodiment, the dosage form is mucosal dosage form. In certain embodiments, the dosage form is a rectal or vaginal dosage form.

[0083] In certain embodiments, the dosage form is formulated as a tablet, enteric coated tablet, enteric coated capsule, dissolve in mouth tablet, dissolve in mouth strip, or capsule, enteric coated granules, granules or pellets. Each possibility represents a separate embodiment of the invention. In certain embodiments, the dosage form is formulated for mucosal delivery. The term "mucosal delivery" refers to the delivery to a mucosal surface, including nasal, vaginal, rectal, urethral, sublingual and buccal delivery. In certain embodiments, the dosage form is formulated in a candy, toffee, dragee, chocolate, cookie or lozenge. In certain embodiments, the dosage form is formulated in a liquid or semi-solid delivery form such as cream, ointment, syrup, spray, foam, liquid, suspension, emulsion, paste, spray and the like, as known in the art.
[0084] In certain embodiments, the dosage form of the cannabinoid, or cannabinoids and licorice or its extract or derivative is targeted to be released at distal (lower) intestine or upon entering the colon. Such formulations are designed to release the cannabinoids essentially at the colon or at the end of jejunum and in the colon or partly in the jejunum and partly in the colon.
[0085] Preferred cannabinoids for colon delivery are anti-inflammatory cannabinoids such as CBDA and THCA, which are not psychotropic. Preferred polymers for producing solid solution of cannabinoids for IBD are pH responsive polymers are polyacrylates Eudragit™. Preferred polymer forming matrix for IBD targeting are polymers that do not degrade by stomach and jejunal enzymes such as dietary fibers, such as pectin and zein. [0086] According to the principles of the present invention, the synergistic or the potentiating anti-inflammatory composition, comprises an“anti-inflammatory cannabinoid component” (i.e. Cannabis-extracted and purified cannabinoid or synthetic cannabinoid or cannabis extract), and optionally a terpene, and a licorice extract or its isolate or derivatives or salts thereof and a dosage form for convenient and efficient delivery of the composition. The advantages of the pharmaceutical composition of the present invention over known cannabis compositions are manifold and include: (a) higher anti-inflammatory pharmacological effect (b) pharmacological anti-inflammatory effect that may replace steroids use (c) analgesic effect and (d) a safe and highly acceptable analgesic and anti- inflammatory medication and (e) low adverse effect medication.
[0087] In some embodiments, a functional inactive ingredient maybe optionally added, such as colorant or antioxidants or chelating agent or microbial preservative or viscosity modifier, pH modifying agents, buffer, or melting point modifier or anti-microbial agent or suspending agent. Licorice
[0088] Licorice is prepared from a Glycyrrhiza plant variety such as (but not limited to) Glycyrrhiza uralensis Fisch., G. inflata Bat. and G. glabra L. The licorice cuts from the dry roots and rhizomes of licorice are widely used in clinical and botanical medicine. Preparations of Glycyrrhiza may be prepared from dry ground plant or from various types of extract of fresh or dried herb and from isolates.
[0089] Anti-inflammatory preparations of licorice may include: Licorice extracts, triterpenes and flavonoids isolates having evident anti-inflammatory properties mainly by decreasing TNF, MMPs, PGE2 and free radicals. Currently, about five hundred and fifty- four drugs containing licorice have been approved by CFDA (china FDA). Isolates of Glycyrrhiza plant species such as Glabra uralensis and others having anti inflammatory activity include (but are not limited to): Alpha- glycyrrhizin Beta-glycyrrhizin glycyrrhetinic acids, licochalcone, Dehydroglyasperin, Isoangustone, Isoliquintigenin, Licoricidin, Glabridin, Echinatin and Licorisoflavan, also named“glycyrrhizanoids” [0090] The bioactive components of Glycyrrhiza include: Glycyrrhetinic Acid and its diglycoside of Glycyrrhizin. The latter generally constitutes about 2-15% of the dry weight of the plant and up to 9.1% can be found in a hydroalcoholic extract thereof, and when identifying both the 18a and 18b isomers of Glycyrrhetinic Acid, their ranges in mg/g dry weight are 0.062-0.475 and 0.015-0.13 respectively. Glycyrrhizic Acid (inactive analogue of Glycyrrhetic Acids), Glabridin within the range of 0.08 to 0.35%, Liquiritigenin (flavonoid; 0.108-2. l74mg/g) and when diprenylated, Glabrol (2.3mg/g dry weight). Also, Isoliquiritigenin (0.073-0.489mg/g), and Liquiritigenin’ s glycoside Liquirtin (0.451- 30.7mg/g; up to 3% Licorice by dry weight). Liquiritigenin is unique to Licorice and Alfalfa. Coumarins (Licopyranocoumarin, Licoarylcoumarin, Glycycoumarin), Formononectin, Glisoflavone, Various prenylated flavonoids (Prenylicoflavone A, Glysasperin A, Licoricidin, Hispaglabridin A, Isoagnusone A, Kanzonol K, and Glycyrrhisoflavone), Various volatiles such as b-caryophyllene oxide, decadienol, 1a, 10a- epoxyamorpha-4-ene, b-dihydroionone, thymol, and carvacrol (mostly related to flavor and scent), Isoangustone A ( Glycyrrhiza Uralensis), Licochalcone A-E (mostly from the inflata species) with at least A and C isolated form Glycyrrhiza Glabra and limited amounts in Uralensis
[0091] The main active component of Licorice is known to be Glycyrrhizin and its metabolite 18-b glycyrrhetinic acid, flavonoids - mainly Liquiritigenin and Isoliquirtigenin - and the subset of polyphenolics based on Glabridin.
[0092] And polysaccharides found in Licorice (bioactive compounds that belong to the carbohydrate class; found in caloric vessels of Licorice but not isolated calorie-free extracts): Glycyrrhizin UC (69,000kDa; L-arabinose, D-galactose, D-glucose, and L- rhamnose at 10:30:27:1 in arabino-3, 6- galactoglucan-type structure) found in Uralensis Glycyrrhizin UA found in Uralensis A collection of lesser known Uralensis polysaccharides (h=10) Glycyrrhizin GA (85,000kDa; L-arabinose: D-galactose: L- rhamnose: D-galacturonic acid: D-glucuronic acid at 22:10:1:2:1) found in Glabra Unidentified pro-immunity polysaccharide [0093] About 20% of the bioactives can be removed from the water extract, which consist of the sweetened fragment (mostly Glycyrrhizin up to 7-25% of the water extract) and flavanoids related to Liquiritigenin (1-1.5% total weight, 5-7.5% of the water extract).

Benefits and uses of the present invention
[0095] The present invention further provides, in another aspect, a composition as described above, or a dosage form as described above, for use in a method of treating an inflammatory disease or disorder. [0096] In certain embodiments, the inflammatory symptom, disease or disorder are selected from the group consisting of: pain associated with cancer, neuropathic pain and HIV-associated sensory neuropathy; side effects of chemotherapy including nausea; symptoms of neurology and neurodegenerative diseases such as Huntington's disease, Parkinson's disease, Alzheimer's disease, amyotrophic lateral sclerosis, multiple sclerosis, epilepsy, post-traumatic stress disorder (PTSD), alcohol abuse, bipolar disorder, depression, anxiety, anorexia nervosa; cancer such as gliomas, leukemia, skin tumors, colorectal cancer; diseases including hepatitis C, methicillin-resistant Staphylococcus aureus (MRSA), pruritus, psoriasis, asthma, sickle-cell disease, insomnia, fatigue, sleep apnea, digestive diseases, inflammatory bowel diseases, collagen-induced arthritis, atherosclerosis and dystonia and geriatric syndromes.
[0097] The composition of the present invention may be beneficial to those with certain liver disorders. In the case of liver fibrosis (scarring), a cannabinoid found in marijuana, specifically, CBD may contribute to the cell death of hepatic stellate cells that contribute to liver scarring. This suggests that CBD may reduce the extent of scarring in the liver when it is damaged.
[0098] In certain embodiments, the cannabinoid responsive disease is selected from inflammatory bowel disease (IBD) such as Crohn's disease, ulcerative colitis, irritable bowel syndrome and intestinal and colon cancers.
[0099] In certain embodiment the cannabinoid or cannabinoids are anti-inflammatory cannabinoids. In certain embodiments, the oral dosage form is resistant to low pH and disintegrates or decomposes and releases the cannabinoid only upon contact with neutral pH intestinal or colon fluids. In certain embodiments, the dosage form is acid resistant and does not release the cannabinoids in a low pH environment. Rather, in this embodiment, the cannabinoids are released at a pH of greater than 6.5 or greater than 7.0. In certain embodiments the solid solution releases the cannabinoids only in presence of pectinases. In certain embodiments the solid solution dosage form releases the cannabinoids only at neutral pH and presence of pectinases, a condition prevailing in the colon. In certain embodiment the solid solution is acid resistant and release the at least one cannabinoid upon crossing the stomach and entering a pH of greater than 6.5 and over at least four hours and more preferably over at least six hours.
[00100] The anti-inflammatory synergistic composition comprising cannabis and licorice, or isolates, fractions or components obtained therefrom, provides many benefits such as increased pharmacological efficacy, use of lower steroid or NSAID concentration, thus having the required therapeutic effect with reduced side effects, prolonged use with a lower dose or period limits or contra indications due to adverse effects. Moreover, the accompanying anti-viral, anti-bacterial and anti-biofilm activity provides great usability in treating inflammation symptoms in conditions of infectious origin or in subjects prone to infection. The composition may be used to both beat and prevent inflammation of both infectious and non-infectious origin.
[00101] Generally, the two main active components of the synergistic combination (i.e. the anti-inflammatory cannabis and the licorice) will be administered together in a single composition. In some cases, however, these two components will be administered in separate compositions - either simultaneously (e.g. the patient will swallow two different oral dosage forms, each containing one of the two active components; or will apply two different topical preparations) or consecutively, in either order.
[00102] Licorice may be prepared in an extract form or in root form. The extract can be prepared in the form ofteas, capsules, tablets, dry powder, and in combination with other herbal remedies. Since the side effects of licorice root are mostly related to the substance glycyrrhizin, most of the clinical research done on the herb is made with modified licorice extract from which most of the glycyrrhizin has been removed. Deglycyrrhizinated licorice (DGL) is usually standardized to contain no more than three percent natural glycyrrhizin. The contents of glycyrrhizin in pure licorice root can be between one and 24 percent but usually is between six to 14 percent. The German Commission E accepts an intake of an average daily dose of 200 to 600 mg glycyrrhizin, which corresponds to five to 15 g of licorice. Licorice root may be used in daily doses from 2 to 15 g for ulcer and gastritis.
[00103] As a treatment for ulcers, a dose of 1.5 to 3g of licorice root daily has been recommended. The maximum dose of glycyrrhizin licorice when used as a flavor ingredient in food and beverages, should not exceed 100 mg per day. Licorice appears to increase cortisol at higher doses (500mg or more), with no significant influence at lower doses; this is related to the glycyrrhizin content and would not occur in deglycyrrhizinated supplements and appears to be a testosterone reduction associated with intake of licorice above 500mg, but the magnitude of this reduction is quite variable and there is no robust information on the topic. [00104] Almost 50 years ago, a scientist by the name of Revers reported that licorice paste reduced abdominal symptoms and caused radiographic evidence of ulcer healing. However, about 20% of patients developed edema, headache and other symptoms due to overdose, leading to a loss of enthusiasm. This led to the development of DGL (deglycyrrhizinated licorice), a form of licorice that does not contain the agents responsible for the side effects such as electrolyte changes. The de-acidified DGL tablet or capsule form used in Europe and America is therefore devoid of any major side effects, and is effective for healing the intestinal membranes. Because it is chewable, it also is helpful to the esophagus. [00105] In the case of oral administration, for systemic delivery, the amount of each of the active components to be administered each day is generally as follows: a) Anti-inflammatory cannabinoid: about 1-1,500 mg/day, more preferably from about 20mg to about 600 mg/day b) Glycyrrhiza extract: about 100 - 2000 mg/day, or about 1.0 to about 20.0 grams of licorice root
[00106] In the case of topical administration, the amount of each of the active components to be administered each day is generally as follows: a) Anti-inflammatory cannabinoid or cannabis extract: 0.01-10 mg/day b) Licorice extract or its isolates: 0.1-100 mg/day [00107] In the case of topical administration to the skin (e.g. in a cream, ointment, gel, foam or lotion), the concentration of each of the active components within the topical dosage form is as follows: a) Anti-inflammatory cannabinoid or cannabis extract: 0.01% - 2.0% b) Licorice extract: 0.1% - 4% or its bioactive isolate from about 0.01% to 2.0% [00108] In the case of topical administration to mucosal membranes such as the eyes
(e.g. by way of eye drops) or oral cavity (e.g. as a rinse solution or suspension), the concentration of each of the active components within the topical dosage form is as follows: a) Anti-inflammatory cannabinoid or cannabis extract: 0.01% to about 2.0% b) Licorice extract or its isolates: 0.1% to about 2.0%
[00109] In the case of parenteral administration by injection (e.g. subcutaneous, intramuscular), the concentration of each of the active components within the injection dosage form is as follows: a) Anti-inflammatory cannabinoid: 0.01% - 2.0% b) Licorice bioactive isolate: 0.1% - 4%

EXAMPLES
IN VITRO WORKING EXAMPLES
[00119] The objective of the following in vitro experiments was to investigate the anti-inflammatory properties of various combinations of a cannabis-derived substance (CBD) and a licorice extract. The potential for synergistic interaction was tested by assaying inflammatory mediator secretion by a macrophage cell line (RAW 264.7), following stimulation with lipopolysaccharide (LPS). The inflammatory mediators assayed were: prostaglandin E2 (PGE2), nitric oxide (NO), TNF-alpha, IL-6, GM-CSF and MCP-
1.
[00120] The study was initiated by preliminary cell-viability dose-response analyses to ascertain the maximal concentrations of the compounds tolerated by the cells. Only non-toxic concentrations were used in the following tests.
[00121] General methods:
[00122] The CBD used in the studies described hereinbelow was 99% pure as tested by HPLC assay. In most cases, the CBD used in the follow study was obtained from IK Hemp S.p.A (Bari, Italy). The licorice extract used in the studies described hereinbelow was spray dried licorice extract flavor 9, obtained from Mafco Worldwide LLC (Camden, New Jersey, USA). This extract has the following composition (w/w percentages measured in the dried material):
Glycyrrhizic acid 8.1
Sucrose 2.0
Hot insoluble 1.2
Loss on drying 1.9
The pH of the composition was 5.0.
[00123] RAW 264.7 monocyte macrophage cells (approximately 4xl05/ml) were seeded in 24 well plates containing 800 microliters/well of complete growth medium (DMEM containing 2mM glutamine, lOOU/ml penicillin and l00pg/ml streptomycin and 10% fetal bovine serum). The cells were then incubated at 37 degrees Celsius with 5% carbon dioxide for 24 h. At the end of this period, growth medium supplemented with lpg/ml lipopolysaccharide (LPS) was added to the cells, together with the test substances (licorice extract, CBD, and their combinations) and various controls, and the cells were then incubated for a further 24 hr. period under the same conditions as before. Following this incubation period, the conditioned medium was aspirated from the various test and control wells and centrifuged at 14,000 g for 5 minutes to remove particulate matter. The clear supernatants were then stored at -70 degrees Celsius prior to assaying the inflammatory mediatory content therein.
[00124] The cytokine/mediator content in the thawed supernatants was assayed using a standard ELISA kit for PGE2 and a colorimetric kit for NO, the details of which are as follows:
ELISA kit for Prostaglandin E2 - Enzo. Cat number ADI-901-001.
Nitrate/Nitrite Colorimetric Assay Kit - Cayman Chemical. Cat number 780001.

Example 1
Synergistic interaction between CBD and Licorice extract in inhibiting Prostaglandin
E2 secretion
[00125] Method: The effect of CBD was investigated on Prostaglandin E2
(PGE2) secretion, as an independent inflammation marker derived from arachidonic acid metabolism. Raw 264.7 macrophage cells were incubated (as described above) in the absence or presence of LPS and treated without or with the CBD, Licorice or a combination thereof for 24 hr. Then, PGE2 levels in the supernatant medium were quantified by ELISA, as explained above.
[00126] Results: As seen in Fig. 1, both the CBD and Licorice extract inhibited LPS- stimulated Prostaglandin E2 secretion to a certain degree, a synergistic effect was observed when tested in lower concentrations. As expected, the induction of inflammation by administration of LPS increased the secretion levels of this pro-inflammatory eicosanoid. The various treatments are indicated as follows: Til (CBD at 3.14, 15.7, 157 and 314 ng/ml and 31.4); TI2 (Licorice at 0.01 and 0.05 mg/ml). Unexpectedly, combination of CBD with Licorice dry extract shows a significant greater reduction of Prostaglandin E2 than the cumulative effect of both of them separately. The results summarized in this figure are shown as the mean of triplicate samples +/- SEM. The statistical significance levels shown in the figure are as follows: *p<0.05 for difference from the naive control. #for significant difference in comparison from the respective stimulated control; $for synergistic effect.
Example 2
Synergistic interaction between CBD and Licorice in inhibiting Nitric oxide secretion
[00127] Method : Raw 264.7 macrophage cells were incubated in the absence or presence of LPS and treated without or with Cannabidiol (CBD, dissolved in Ethanol), Licorice (dissolved in media) or a combination thereof for 24 hr. Then, Nitric oxide (NO) levels in the supernatant medium were quantified by colorimetry, as explained above.
[00128] Results: The results of this study are presented in Fig. 2, in which the various treatments are indicated as follows: Til (CBD at 3.14, 15.7, 157 and 314 ng/ml and 31.4 ); TI2 (Licorice at 0.01 and 0.05 mg/ml). As expected, the induction of inflammation by administration of LPS increased the secretion levels of NO. Moreover, CBD alone attenuated NO secretion in a biophysical manner, whereas Licorice did not cause any significant decrease in NO secretion. Unexpectedly , several combinations of these compounds, caused a much greater than additive inhibitory result, indicating a synergistic interaction between them. The results summarized in this figure are shown as the mean of triplicate samples +/- SEM. The statistical significance levels shown in the figure are as follows: *p<0.05 for difference from the naive control. #for significant difference in comparison from the respective stimulated control; $for synergistic effect.
Example 3
Synergistic interaction between CBD and Glabridin 40%, (Licorice extract) in inhibiting Nitric oxide secretion
[00129] Method : Raw 264.7 macrophage cells were incubated in the absence or presence of LPS and treated without or with Cannabidiol (CBD, dissolved in Ethanol), Glabridin 40% (dissolved in media) or a combination thereof for 24 hr. Then, Nitric oxide (NO) levels in the supernatant medium were quantified by colorimetry, as explained above.
[00130] Results: The results of this study are presented in Fig. 3, in which the various treatments are indicated as follows: Til (CBD l.0pg/ml and 0.5 pg/ml); TL· (Licorice at 1.0 pg/ml and 0.1 pg/ml). As expected, the induction of inflammation by administration of LPS increased the secretion levels of NO. Moreover, CBD alone attenuated NO secretion in a biophysical manner, whereas Glabridin 40% did not cause any significant decrease in NO secretion. Unexpectedly, several combinations of these compounds, caused a much greater than additive inhibitory result, indicating a synergistic interaction between them. The results summarized in this figure are shown as the mean of triplicate samples +/- SEM. The statistical significance levels shown in the figure are as follows: *p<0.05 for difference from the naive control. #for significant difference in comparison from the respective stimulated control; $for synergistic effect.

As expected, the induction of inflammation by administration of LPS increased the secretion levels of PFE2. However, CBD alone or GA alone at the specified concentrations did not inhibited the PGE2 secretion in a biophysical manner. Unexpectedly, the combination of CBD with GA significantly inhibited PGE2 secretion, indicating a potentiating interaction between them. The results summarized in this figure are shown as the mean of triplicate samples +/- SEM. The statistical significance levels shown in the figure are as follows: *p<0.05 for difference from the naive control. #for significant difference in comparison from the respective stimulated control; $for synergistic effect.
