Description

Yin-nourishing and sore-throat-relieving pharmaceutical composition
Technical Field
The invention belongs to the field of traditional Chinese medicines, and relates to a yin-nourishing and sore-throat-relieving pharmaceutical composition. Specifically, the invention relates to a yin-nourishing and sore-throat-relieving tea bag. The invention also relates to a quality control method and pharmaceutical application of the pharmaceutical composition.
Background
Pneumococci and hemolytic streptococcus often cause adverse inflammatory stimulation to pharyngeal mucosa and tonsil, so that acute and chronic pharyngitis, deficiency and pharyngitis are the symptoms of acute and chronic pharyngitis, dry cough, intractable and recurrent attacks[1,2]. Heat-toxicity and wind-cold tend to lead to qi and blood stasis, which often induces throat diseases in qi and blood with imbalance of yin and yang, so acute and chronic pharyngitis, which is "yin-yang stagnation" in the "internal classic", and deficiency of yin of the throat, lung and kidney, often leads to stagnation of deficient fire. The traditional Chinese medicine is characterized by applying dialectical treatment of blood stasis and qi deficiency, such as a kidney warming and lung moistening method, a qi circulation and spleen tonifying method, a yin nourishing and sore throat relieving method, a kidney warming and yang strengthening method, a qi circulation and blood activating method and the like.
The traditional Chinese medicine acupoint application method, acupuncture therapy, moxibustion therapy, electric needle and acupoint injection method, etc. can be used for treating acute and chronic pharyngitis by synthesizing traditional Chinese medicine according to channels and collaterals, traditional Chinese medicine intravenous injection method, traditional Chinese medicine aerosol inhalation method, etc[3-6]
He hong, etc[7]Respectively applying the experience of using the self-prepared Yinma decoction to treat 35 patients with chronic pharyngitis and applying the experience of using the self-prepared mulberry cicada cough relieving prescription to 45 patients with chronic pharyngitis. Usually for external treatmentTreatment measures including massage, acupuncture therapy and ultrasonic atomization of traditional Chinese medicine decoction[7-12]
Xufei, Shenyan plum, etc[9,10]The use of the Shuanghuanglian injection for ultrasonic atomization treatment of chronic pharyngitis patients has experience of ultrasonic atomization treatment of the extracted liquid medicine in the clinical process, wherein the total effective rate of a treatment group is up to 97.5 percent in the treatment of the patients with chronic pharyngitis through ultrasonic atomization of the Shuanghuanglian injection. Zhao Yujuan and He Miao[13,14]The seven-ingredient throat-clearing aerosol and the three-volt patch are respectively used for carrying out correlation research on the chronic pharyngitis, and the satisfactory clinical curative effect is obtained. Besides, there are warm wood[15]The ginger juice is mixed with the mixed powder of the euphorbia kansui, the asarum, the white mustard seed and the like to form the ointment, and the effect is also satisfactory in the application research of plaster cultivation, Tiantu point, Dazhui and Feishu application.
The non-bacterial inflammation is the cause of pharyngitis, has the clinical characteristics of stubborn symptoms, long lingering and difficult-to-cure course and the like, and can directly influence the life and work of people. Western medicine treatment is widely applied in clinic, but mainly takes antibiotic medicines, sometimes the curative effect is not obvious, and some serious side effects can be caused; the traditional Chinese medicine in China is obviously different from western medicine, and focuses on the overall disease and emphasizes dialectical treatment methods, so that the treatment effect is more satisfactory, and the side effect is small[8-11]. However, the application of the traditional Chinese medicine preparation in clinical practice is relatively limited, and a large-scale experiment for treating pharyngitis in traditional Chinese medicine is lacked, so more scientific clinical research is needed.
Pharyngitis, which is characterized by repeated attack and prolonged course of disease, often brings adverse effects on daily life, study and work of patients, and causes great trauma to physical and mental health of patients. The chronic condition development, pharyngeal mucosa and submucosal microcirculation system are often stimulated by inflammatory factors, the tissues can be anoxic, metabolic disturbance and glandular secretion disorder can occur, and chronic stimulation continuously stimulates pharyngeal nerve endings, so the condition of the patients is gradually aggravated, and the use of antiviral and antibiotic medicines in clinic can not achieve satisfactory treatment effect[9-13]
The novel coronavirus pneumonia (Corona Virus Disease 2019, COVID-19) belongs to the category of epidemic diseases from the perspective of Chinese medicine. The pneumonia patients infected by the novel coronavirus have the main clinical manifestations of fever, hypodynamia and dry cough, and all show certain symptoms of pharyngeal inflammation. The clinical manifestations of the patients with the mild cold-damp stagnation lung disease of the new coronary pneumonia comprise fever, hypodynamia, cough, expectoration and the like, and the clinical manifestations of the patients with the damp-heat stagnation lung disease also comprise dry cough, little phlegm and pharyngalgia.
The ancient Chinese medical record of "tea is a medicine for treating diseases. The research shows that the tea contains the ammonia theophylline, the tea polyphenol, the caffeine, the theophylline, the theobromine and the like, has the effects of treating and protecting health for a plurality of diseases, and particularly has the effects of reducing blood pressure, preventing and treating arteriosclerosis, resisting radiation, preventing cancer, helping digestion, relieving fatigue and the like[16]. Although tea has many pharmacological actions of traditional Chinese medicines, the effective action is very little.
Tea culture is an important component of the traditional culture of China. From ancient times to present, the health care tea has positive influence on life and health care of people. The medicinal tea, namely the tea agent, is an important member of the traditional Chinese medicine treasury, and is popular like drinking tea, and the tea and the Chinese herbal medicines are brewed or decocted for drinking, so that the aim of daily disease prevention is fulfilled. The Guangya of the ancient medical books Zhang Yuan, the Song of Sunzhu, the Shennong's herbal notes of the pottery Hongjing, the Qianjin key prescription of the Sun Si, the Waitai secret of the Wang boil all have descriptions of the selection and action of the herb tea, and many new prescriptions of the herb tea appear in order to drink the health-care herbs from Hou to civilians up to the emperor[16,18]
The bagged Chinese medicine tea is prepared through processing tea into coarse powder, packing in paper bag, soaking in boiling water to eliminate dregs and drinking liquid medicine. The traditional Chinese medicine powder is developed from ancient Chinese medicine powder boiling and drinking agents, and has the effects of benefiting qi, assisting exhaustion, regulating yin and yang, removing evil, washing viscera and caring skin. The bagged steeping drug has large dosage, small volume, convenient taking and quick dissolution, furthest retains the advantages and characteristics of the traditional decoction, is more close to the living habits of the masses, effectively develops the traditional decoction excessively and invisibly into the mainstream of the popular drug dosage form[17,19]
The traditional Chinese medicine bagged steeping preparation is firstly researched in Japan in the 70 th century in 20 th century, Chinese also has special research on the traditional Chinese medicine bagged steeping preparation in the 80 th century in 20 th century, particularly more detailed research on the aspects of preparation process, effective leaching rate, pharmacological action, clinical application and the like of the traditional Chinese medicine bagged steeping preparation is carried out, and blood pressure reducing tea bags, eight-treasure tea bags, Sichuan peony tea bag and the like are recorded in drug Standard of Ministry of public health of the people's republic of China[18]
In the actual tea bag, due to the consideration of use and economic value, the tea leaves are beaten into fan-shaped fragments to form a basic flow, which is in conflict with the aesthetic concept of famous tea, even if part of the tea bag is packaged by the tea bag, the tea bag is only required by overseas markets, and the development of the tea bag in the Chinese market is limited to a great extent[19-21]. The original tea bag which does not break the tea and keeps the original shape of the tea seems to better meet the requirements of consumers in China.
The preparation process of the bagged steeping drug is simple, can keep effective components as much as possible, has the characteristics of high leaching rate, quick response, convenient taking and the like, and in recent years, the method for improving the leaching rate of the effective components of the medicinal materials is more and more emphasized, so that the research on special preparation processes is gradually increased, the quality and quantity are optimized, and the satisfactory result is obtained.
In order to seek a new method for treating pharyngitis, in particular pharyngitis and other symptoms and/or symptoms caused by novel coronavirus pneumonia, the life quality of a patient is improved, in particular the relapse of chronic pharyngitis is controlled, and the traditional Chinese medicine external treatment method is started to be used clinically. In addition, considering that the common traditional Chinese medicine method is simple and easy, the misuse and abuse of antibiotic medicines can be effectively reduced, the adverse reaction is reduced, the long-term effect is satisfactory, and the Chinese medicinal preparation is worthy of being popularized and used in clinic.

Figure BDA0002524127550000052
the composition principle of the prescription is firstly seen in the Suwen-Zhi-Zhen-Yao university treatise on 'the principle that the principal disease is monarch, the assistant is monarch and the assistant is guide'. The principle of the prescription is enriched and expanded by doctors of all generations on the basis.
1. Monarch drug
It is a drug that has a main therapeutic effect on major diseases or major symptoms, i.e., it is designed to target at the main etiology, leading pathogenesis or major symptoms of the disease, and it is the core part of the prescription composition. Monarch drugs generally have the characteristics of stronger potency, less medicinal taste and relatively larger dosage. "major is the principal" means relative to the conventional dosage of the drug itself, rather than the absolute dosage in the formulation compared to other drugs, e.g., limited by the texture, quality and toxicity of the drug itself, e.g., lighter in light floral leaf type; the dosage of heavy materials such as shells is heavy; the dosage of the medicinal materials with strong quality and strong power is preferably small, otherwise, the dosage can be slightly large; the toxic herbs such as Wu Tou are used in small dosage even as monarch drugs.
2. Ministerial drug
The ministerial drugs have two layers: 1) auxiliary monarch drug for strengthening the drugs for treating the major diseases or the major symptoms; 2) the medicine has main treatment effect on accompanied diseases or concurrent symptoms. The medicine has more medicinal flavor than the monarch drug, and the potency and the dosage of the medicine are smaller than those of the monarch drug.
3. Adjuvant drug
The adjuvant has three layers: 1) adjuvant drugs, i.e., drugs that combine monarch and ministerial drugs to enhance therapeutic effects, or drugs that directly treat secondary symptoms; 2) adjuvant drugs, which refer to drugs that eliminate or relieve the toxicity and side effects of monarch and ministerial drugs; 3) the anti-adjuvant drugs are the drugs with the property of being opposite to that of the monarch drugs and playing the role of the other drugs in the treatment when the drugs reject the disease.
4. Medicine for taking care of the drugs
The guiding drugs have two meanings: 1) the channel-guiding medicine can guide the efficacy of the traditional Chinese medicine to directly reach the focus; 2) the harmonizing herbs can harmonize the properties of the herbs in the recipe, coordinate the interaction of the herbs or correct the taste. The dosage of the drug is small and the number of the drugs is small.
Without being bound by theory, the inventors speculate one possibility as follows:
radix Pseudostellariae and green tea are used as principal drugs;
lotus leaf, mint, folium isatidis, fructus forsythiae, burdock and rhizoma cimicifugae, which can raise the clear and descend the turbid, clear the throat and relieve sore throat, are used as ministerial drugs;
radix Paeoniae Rubra and radix Ophiopogonis as adjuvant drugs;
