Description

A kind of composition containing loquat flower and application
Technical field
The invention belongs to drug field, more particularly, to a kind of composition containing loquat flower and application.
Background technology
Loquat flower system the rose family Eriobotrya loquat Eriobotrya japonica (Thunb) Lindl flower, distribution In provinces and regions such as China Zhejiang, Jiangsu, Sichuan, Guangxi.Its is lightly seasoned according to records, warm-natured, enters lung channel.Researching and analysing in recent years shows Loquat flower is nutritious, especially containing higher nutrient calcium, iron, zinc etc..In addition, loquat flower is rich in protein, 18 kinds Amino acid, especially needed by human 8 kinds of amino acid, fat, vitamin, crude fibre, carbohydrate, mineral constituents contents are equal It is higher, there is higher nutritive value.Loquat flower contains the medicinal ingredients such as triterpenoid saponin, have resolving sputum, cough-relieving, preventing and treating headache, Cold and other effects, triterpene compound has multiple biological activities, in recent years it has also been found that some compounds have AntiHIV1 RT activity and resisted swollen Tumor activity, thus paid attention to by researcher, in addition, loquat flower still makes the good raw material of natural health-care beverage.
Chronic pharyngitis is the chronic inflammation of pharyngeal mucous membrane, submucosa and lymphoid tissue, depending on its lesion situation, can be divided into list Pure property, Hypertrophic and atrophic three types.The pathogenic factor of chronic pharyngitis is a lot, such as acpuei pharyngitis recurrent exerbation and neighbouring device Official's disease (chronic tonsillitis, gingivitis, rhinitis chronic, chronic nasosinusitis) etc. can all cause.External cause very cold is dried, work The air made in environment is polluted by dust, chemical gas, tobacco and wine and pungent diet long-time stimulus, and is used due to occupational factor The excessive people of throat is susceptible to suffer from chronic pharyngitis.In addition, it is irregular, tired, nervous to live for a long time, can make under passive protective physical fitness Drop, bacterium and the easy repeated infection of virus, can also cause chronic pharyngitis.The pharyngeal sense of discomfort of chronic pharyngitis or foreign body sensation, dry, scabies Gargalesthesia, burning heat sensation, hypodynia sense is pharyngeal to have phlegm etc., but without prejudice to feed;Foreign matter sense of obstruction is obvious when saliva is swallowed, but enters dry Property food when then unobvious, the above is felt often cause very brief and frequently cough, more acute from morning, and easily causes nausea; With during the air that throat is excessive, abrupt change of climate or suction are dry and cold and after tobacco and wine, above-mentioned symptom can aggravate, and check visible pharyngeal mucosa Chronic congestion, the drying of pharynx rear wall or lymph foilicie hyperplasia.To sum up, the cardinal symptom of chronic pharyngitis be it is pharyngeal have a foreign body sensation, it is pharyngeal Dry, cough etc. is not cardinal symptom.
The normal recurrent exerbation of the state of an illness of chronic pharyngitis, does not recover for a long time, is acquired a certain degree of difficulty in treatment, in addition to microorganism infection, changes Pharyngeal inflammation can also be caused by learning the stimulation of material.In addition, chronic pharyngeal a big chunk be not due to it is bacterial, but Caused by some long-term physical chemistry stimulate.The method for the treatment of chronic pharyngitis is many at present, advocates as doctor trained in Western medicine With the gargles such as mouth Thailand, Dobell's solution, buccal Dobell, Anji lozenge etc..These medicine long-term uses can cause oral cavity Interior environment disturbance.For plump hyperplastic pharyngitis, the methods of laser, microwave, freezing can be used.But these therapies have abuse at present Trend, outpatient service be frequently seen because the serious hyperplasia of the pharyngeal scar of Post operation, contracture and aggravation comes medical patient.Chronic pharynx The scorching cause of disease is complex, the normal recurrent exerbation of the state of an illness, does not recover for a long time, is acquired a certain degree of difficulty in treatment, very refractory to be cured, and can only be slow Symptom is solved, at present, the traditional Chinese medical science can improve the state of an illness in terms of chronic pharyngitis is treated, compared with doctor trained in Western medicine.
