Description

Traditional Chinese medicine composition for treating cataract caused by liver-kidney yin deficiency and qi and blood stasis, and preparation method and quality control method thereof

Technical Field

The invention relates to a traditional Chinese medicine composition for treating cataract with the symptoms of liver-kidney yin deficiency and qi and blood stasis, a preparation method and a quality control method thereof. The invention belongs to the technical field of medicines.

Background

The modern society has fast life rhythm and high pressure, and people are easy to cause cerebral nerve dysfunction, thereby causing emotional disorder, hurting liver and kidney, and qi stagnation, and further causing various diseases by liver and kidney yin deficiency. The old people with spleen and stomach hypofunction often have the defects of ingestion and qi and blood biochemical insufficiency, and can affect liver and kidney functions. Most importantly, the daily level of life of modern people is improved, the food intake of high calories is increased, and the substances are spicy and hot when being addicted to cigarette and wine, and have warm and dry nature, and are easy to burn and consume liquid, and damage yin and fluid. Leading to an increasing number of patients suffering from cataract due to deficiency of liver-yin and kidney-yin and glaucoma. Cure and resolution of such afflictions is critical.

The increasing number of cataract patients caused by yin deficiency of liver and kidney can lead to vision deterioration of the patients, and the transparent crystals in the human eyes can be turbid. Early cataract onset, and its associated symptoms are not obvious. Generally, the visual blur is slightly seen, and thus the attention of a patient is difficult to be paid. The patient may be mistaken for eyestrain or presbyopia without going to a hospital visit. Patients in the middle of cataract onset have more cloudy lenses, form more blurred vision, and may cause abnormal symptoms such as glare, myopia, strabismus, etc. After the condition is more serious, cataract patients may even lose sight. The disease has long disease course, is mainly seen in old patients, has two means of operation treatment and drug treatment for the treatment of the old patients, and is suitable for drug treatment if the disease is early; if the disease is chronic and nebula, but three lights are still visible, surgery is preferable; if the crystal beads are grey and turbid, the pupil spirit is obviously obstructed, the medicine treatment is difficult to work, and the operation treatment is carried out after the nebula is fixed and the obstacle is aged.

The recipe is called "round nebula" as cataract. One of the round nebula and the internal disorder is first found in "Peronous ophthalmic Dragon Lun", but the treatment of this disease is recorded as earliest in "external Tai Mi Yao". The book "eye disease" is: the eyes are caused by no cause, suddenly feel the membranous, are not painful and itching, are gradually unknown, and are lost after the years of age. The eyes are different in appearance, but only in the small beads, the eyes are blocked, and the eyes are bluish white, and the eyes are clear of bright and dark lights, and the eyes are clear of the eyes. Thus, it is called as brain flow blind eye. When the eyes are not affected, fly black seeds are seen before the eyes are carelessly, and the eyes are gradually moved up and down, so the Jinzhi formula is preferred. After one needle, the clouds are broken and the sun is seen. The ancient people misused the disease to be blindness due to the formation of a cataract caused by cerebral lipid flow, so the disease is called cerebral flow blue blindness. Although the perspective is wrong, the Jin Bijue, namely the earliest ophthalmic surgery treatment operation, namely the needle barrier removal operation, is the earliest record of the ophthalmic needle barrier removal operation in the traditional Chinese medicine literature, and lays clinical and theoretical foundation for the development of the ophthalmic surgery technology of the later-generation traditional Chinese medicine.

The syndrome differentiation and the syndrome differentiation are combined, and the whole body and the local are associated, so that the principle of treating both principal and secondary aspect of disease is established, and the syndrome of the recipe (the eyesight improving and kidney nourishing tablet) is liver-kidney yin deficiency and qi and blood stasis. "Lingqiu-Tiannian" is: fifty years old, liver qi failing, liver leaves thin, bile going out and eyes going unclear. "deficiency of liver-yin and kidney-yin, deficiency of essence and blood, malnutrition of eyes, and blurred vision due to gradual mixing of crystal beads; kidney governs bone, kidney stores essence, essence and produces marrow, and marrow belongs to brain, liver and kidney yin deficiency, brain marrow and bone malnutrition, so dizziness, tinnitus, soreness and weakness of waist and knees. A red tongue with thin coating and a thin pulse is a pattern of yin deficiency. Malnutrition of the eyes, obstruction of blood vessels and stagnation of qi and blood stasis are caused by long-term malnutrition of the eyes. Therefore, it is indicated for liver and kidney, and also has the actions of resolving stasis, resolving hard mass and improving vision.

Patent application publication No. CN1456296A discloses a granule for improving eyesight and nourishing kidney and a preparation method thereof; the patent application with publication number of CN1548090A discloses a pill for improving eyesight and nourishing kidney and a preparation method thereof, the contents of the two patents are respectively granules and pills, the formula, the preparation method and the clinical curative effect are different from those of the pill, and the pill is inconvenient for patients to carry and take, and meanwhile, the preparation method is easy to cause the degradation of lutein serving as an active ingredient in wolfberry fruit; and the cassia seed extract can cause a great deal of loss due to viscosity, so that the transfer rate of the active ingredient chrysophanol is lower, and the treatment effect of the medicine is affected. Meanwhile, the glossy privet fruit is directly crushed to prepare the preparation, and fat grease in medicinal materials of the preparation is easy to cause difficult tabletting and forming, so that friability and disintegration time are influenced, and product quality is influenced.

Disclosure of Invention

The invention aims to provide a traditional Chinese medicine composition for treating cataract caused by deficiency of liver-yin and kidney-yin and stagnation of qi and blood, a preparation method and a quality control method thereof.

In order to achieve the above purpose, the invention adopts the following technical means:

the invention relates to a traditional Chinese medicine composition for treating cataract caused by yin deficiency of liver and kidney and qi and blood stasis, which is prepared from the following raw materials in parts by weight:

100-500 parts of medlar, 100-400 parts of glossy privet fruit, 50-300 parts of rehmannia, 50-220 parts of cassia seed, 50-250 parts of chrysanthemum and 30-150 parts of achyranthes root.

Preferably, the traditional Chinese medicine composition is prepared from the following raw materials in parts by weight:

400 parts of medlar, 300 parts of glossy privet fruit, 200 parts of rehmannia, 220 parts of cassia seed, 200 parts of chrysanthemum and 100 parts of achyranthes root. Or alternatively

The traditional Chinese medicine composition is prepared from the following raw materials in parts by weight:

200 parts of medlar, 150 parts of glossy privet fruit, 100 parts of rehmannia, 100 parts of cassia seed, 100 parts of chrysanthemum and 50 parts of achyranthes root.

The Chinese wolfberry fruit, fructus Lycii, sweet and flat. It enters liver, kidney and lung meridians. Nourishing liver and kidney, replenishing essence and blood, improving eyesight and the highest dosage. Essence and blood are the material basis of kidney yin and kidney yang, and medlar nourishes liver and kidney essence and blood, and essence and blood are sufficient to nourish yin of liver and kidney. Such as "Ben Cao Jing Ji Zhi" (materia Medica of concentrated injection): "tonify essence and Qi, strengthen vagina". "the Chinese wolfberry fruit, fructus Lycii, with good effect of improving eyesight, can be used for treating dim eyesight and hypopsia caused by deficiency of liver and kidney essence and blood, and is an essential herb for ophthalmology, so it is" improving eyesight "in Ben Cao gang mu". Glossy privet fruit, fructus Ligustri Lucidi, sweet, bitter and cool. It enters liver and kidney meridians. Tonify liver and kidney, clear deficiency heat and improve vision. The glossy privet fruit is sweet in flavor, can nourish yin of liver and kidney, is bitter and cool, can clear deficiency heat, is especially good at treating the symptoms of yin deficiency and fever of liver and kidney, and is a good product for clearing and nourishing because the tested product is nourishing but not greasy and is cool in nature. For cold syndrome of kidney-yang, it is a key herb for clearing heat and replenishing essence, with its flavor and smell of yin. In addition, the glossy privet fruit has the effect of improving eyesight and is used for treating the vision decline and the dim eyesight caused by the deficiency of liver-yin and kidney-yin. Such as "Ben Cao Bei Yao": "benefit liver and kidney, calm five viscera, strengthen waist and knee, improve ear and eye, blacken beard and hair, tonify wind deficiency, and remove hundred diseases. Both of them are good drugs for improving eyesight, and they are homologous to each other in terms of liver and kidney, and supplement each other in terms of essence and blood, both liver and kidney and yin. Fructus Lycii to obtain fructus Ligustri Lucidi, the tonifying effect is increased; the fruit of glossy privet is good at relieving fever due to yin deficiency because it is good at relieving dryness. In the recipe, rehmannia root is sweet, bitter and cold. It enters heart, liver and kidney meridians. Clear heat and cool blood, nourish yin and promote the production of body fluid. For long time, yin deficiency generates heat, so the dried rehmannia root, dried orange peel, fructus Ligustri Lucidi is used to treat deficiency heat together with the actions of clearing heat and nourishing yin, and reinforcing the tonifying effect. The three herbs complement each other and the phase is indicated for the root cause of yin deficiency of liver and kidney. For long-term yin deficiency of liver and kidney, yin failing to control yang and causing hyperactivity of liver yang, chrysanthemum and cassia seed are used to calm liver yang, clear liver and improve vision. Chrysanthemum is pungent, sweet, bitter and slightly cold. It enters liver and lung meridians. Clear heat, calm liver and improve vision. Chrysanthemum and Lycium chinense are combined to clear heat, nourish liver and improve vision. Semen Cassiae is sweet, bitter and slightly cold. Enter liver and large intestine meridians. Clear liver and improve vision, moisten intestines and relieve constipation. It is indicated for constipation due to liver heat and also gives heat evil out of the way. Chrysanthemum and semen Cassiae are both indicated for the syndrome of liver yang hyperactivity by clearing heat and pacifying liver. Achyranthes root, radix Achyranthis bidentatae, bitter and sour, and it is flat. It enters liver and kidney meridians. Promoting blood circulation, removing blood stasis, tonifying liver and kidney, strengthening tendons and bones, promoting urination and treating stranguria. For the long-term malnutrition of eyes, the blood vessels are not smooth and qi and blood stasis is blocked, so it is combined with niu xi to activate blood and remove stasis, tonify liver and kidney and strengthen tendons and bones. It is good at descending because it can tonify by walking in Ben Cao Jing Shu. In addition, niu xi Shang Shangke has the actions of inducing diuresis to treat stranguria, inducing diuresis and promoting blood circulation to remove blood stasis.

The whole prescription has six herbs, so the herbs are less powerful and obvious in main and secondary aspects. It has the effects of nourishing liver and kidney, improving eyesight, resolving hard mass, and removing blood stasis. Supplement each other and act appropriately, so it is indicated for cataract due to deficiency of liver-yin and kidney-yin and qi and blood stasis.

In addition, this recipe can also be used to treat five wind internal obstruction (glaucoma) due to hyperactivity of liver yang. Glaucoma is an eye disease which causes damage to the disk and visual field defect and even blindness due to pathological ocular hypertension, and corresponds to liver-yang hyperactivity which is a five-wind internal barrier in the traditional Chinese medicine. Glaucoma belongs to the category of five wind internal barrier (green wind, yellow wind, black wind and black wind), lei Tou wind and head deflection wind in traditional Chinese medicine. Ancient people named wind indicated that the disease was severe, pain was severe, and the changes were rapid and the harm was severe. Five wind types are classified according to etiology and clinical manifestations. "great formation of mesh: the symptoms are wind, fire and phlegm, the diseases are in strong cross attack, headache and eye pain are acute, jin Jingxian is dispersed, and then the spirit and water appear a certain color along with a certain viscera, namely five wind. "the" Yizongjin Jian-ophthalmic heart law key formula "says that: the pupil turns yellow, which is named yellow wind; the person turning green and white is named as green wind; the person turning black is named as black wind; the person who turns red is named as wufeng; the person who turns cyan is called cyan wind. Since the five pupils have the changes of size and color and the later stage has the clouding of crystal beads, they are all in the category of internal obstruction, so they are called five wind internal obstruction. Lei Tou wind and migraine wind both have severe headache, including headache caused by ocular diseases, such as glaucoma, or ocular diseases caused by headache. Liver fire can generate wind, liver yang can dispel wind, liver opens into eyes, so the occurrence and development of the disease are most closely related to liver. Since mydriasis belongs to kidney and liver and kidney are homologous, qi and blood disharmony, adverse effect of eyes and orifices and accumulation of water and spirit can be caused by excessive liver and kidney wind-fire, liver and kidney yin-yang, qi stagnation of liver and spleen and internal generation of turbid phlegm. Ancient people also noted local factors of this disease, wang, foreign secret, volume twenty-one eye diseases, different climates, say: the sources of this disease are the same as those caused by the deficiency of the internal hepatic duct and the eye obstruction. The five wind internal disorder treated by the recipe (MINGMUZISHEN tablet) is yin deficiency and yang hyperactivity type. Yin deficiency of liver and kidney, hyperactivity of yang-qi, wind-transforming into liver-yang, ascending of wind-yang, disturbance of qi and blood stasis, headache, eye distention, hard eyes, dizziness and tinnitus. Yin is astringing, yang is dispersing, yin deficiency and yang hyperactivity cause mydriasis and deficiency of yin and blood are small, and mydriasis is malformed. Deficiency of liver-yin and kidney-yin, deficiency of essence and blood, amnesia and insomnia due to malnutrition of brain, soreness of waist and knees due to malnutrition of bones. The yin fluid cannot be applied to the mouth, and the mouth is dry and the pharynx is dry. The tongue pulse also manifests as yin deficiency. In the recipe, ju Hua and Jue Ming can calm liver yang and treat liver yang hyperactivity (symptoms caused by high eye pressure), which means to treat the disease by differentiation.

Experimental example 1 extraction of Lycium barbarum

The wolfberry fruit plays a role in the traditional Chinese medicine composition as a monarch drug, modern researches show that the wolfberry fruit contains a large amount of lutein, wolfberry polysaccharide, free amino acid, betaine, vitamins and other substances, wherein the lutein plays an important role, and is spread over the outer retina makeup layer, so that the lutein is important for the development of retina, and the researches show that the lutein can be supplemented to remarkably reduce the senile macular degeneration (AMD) and reduce the risk of cataract development, and meanwhile, the disease condition of cataract patients is obviously improved. The quality of the wolfberry fruit extract plays a vital role in the curative effect of the traditional Chinese medicine composition, and the content of lutein directly influences the curative effect of the product.

Meanwhile, the shape of the percolator is generally cylindrical and conical, the shape of the percolator is selected relative to the expansibility of medicinal materials, the pressure center of the cylindrical percolator is arranged at the bottom of the tank, the conical part of the conical percolator can disperse partial pressure of the bottom of the tank, the cylindrical percolator and the conical part of the conical part are applicable to different medicinal materials, and the percolating effects are different.
