FIG. 1 is a graph showing the statistical results of the administration effect of the extracts of the Chinese medicinal composition in the application example of the present invention.
[ detailed description ] embodiments
The invention is further described with reference to the following figures and embodiments.
Infectious pneumonia belongs to the epidemic disease category in traditional Chinese medicine, the winter and spring seasons are the high-incidence seasons of epidemic diseases, the pathogeny often occurs when healthy qi of a human body is insufficient and the qi of ying and wei is not solid, and the pathogenic factors such as dampness, heat, wind, cold and the like invade the body while the body is still hot, and the pathogenic factors enter the interior to transform into heat.
The applicant conjectures that damp turbidity is accompanied with heat toxin according to the reported symptoms, and the accumulation of damp-heat is the main pathogenesis of the novel coronavirus pneumonia: the applicant considers that the treatment mainly comprises clearing heat, dispersing wind, clearing lung, detoxifying, expelling pathogenic factors, strengthening spleen, eliminating dampness, relieving cough and reducing sputum, and the like, because the heat blocks qi movement and the lung qi movement is dispersed, purified and descended, so that the symptoms of cough, chest distress, breath holding and the like are caused, and the symptoms of transportation and transformation disorder, dampness turbidity and internal stagnation, caused by the dampness invading spleen and stomach, fatigue, weakness, gastrointestinal discomfort and the like are caused.
[ composition formulation ]
The embodiment of the invention provides a traditional Chinese medicine composition which comprises the following components in parts by weight: 10-20 parts of honeysuckle, 10-20 parts of dandelion, 5-15 parts of houttuynia cordata, 5-15 parts of agastache rugosus, 5-15 parts of poria cocos, 5-15 parts of coix seeds, 4-8 parts of dried orange peel, 4-8 parts of mint, 4-8 parts of platycodon grandiflorum, 25-35 parts of fresh reed rhizome, 4-8 parts of ginger and 4-8 parts of Chinese dates.
The traditional Chinese medicine composition has a reasonable formula, and honeysuckle flower has the effects of clearing away heat and toxic materials and cooling and dispersing wind heat according to the formula of the traditional medicine; the dandelion has the effects of clearing away heat and toxic materials, promoting urination and dissipating stagnation; the heartleaf houttuynia herb clears away heat and toxic materials, eliminates carbuncle and expels pus; fresh rhizoma Phragmitis has effects of clearing heat, promoting fluid production, purging pathogenic fire, and relieving restlessness; the four herbs are monarch drugs for clearing lung heat to remove toxicity and dispersing lung qi to clear and descend.
Poria has effects in promoting diuresis, eliminating dampness, invigorating spleen, and calming heart; the coix seeds have the effects of tonifying spleen, promoting diuresis, clearing heat and expelling pus; pericarpium Citri Tangerinae has effects of regulating qi-flowing, invigorating spleen, eliminating dampness and eliminating phlegm; the three medicines have the effects of eliminating dampness and strengthening spleen, and the platycodon root is matched to diffuse lung and eliminate phlegm, relieve sore throat and relieve cough, so that the platycodon root has the effects of clearing and resolving heat phlegm, and the four medicines are used as ministerial medicines.
The mint is pungent and cool and disperses, and can disperse wind and heat, clear and relieve headache and eyes; herba Agastaches is pungent in flavor and warm in property and can repel dirt, promote qi circulation and eliminate pathogenic factors, and harmonize the middle warmer and dispel dampness; the two herbs are both exterior-releasing herbs, but they are pungent but not drastic, warm and cool in combination, neither dry nor cold, and can enhance the action of promoting the circulation of exterior.
Ginger dispels cold to arrest cough, and jujube invigorates qi and nourishes blood, so the two herbs can harmonize the property of the medicine and improve the qi of ying and wei, and are also used as guiding herbs.
The combination of the medicines can clear heat toxin, eliminate dampness, promote the smooth lung qi and eliminate fever, cough, chest distress and breath holding.

And when the membrane concentrated feed liquid reaches 0.5-1.5 Baume or the concentration cycle time of the feed liquid exceeds 4 hours, receiving the feed liquid.
Step 6, vacuum concentration: and (3) carrying out vacuum concentration on the membrane concentrated solution, wherein the concentration temperature is 35-45 ℃, and the vacuum degree is lower than-0.095 MPa. And collecting when the concentrated extract is 28-32 Baume.
Step 7, natural solidification: naturally solidifying the concentrated extract at 30-45 deg.C under vacuum degree lower than-0.097 MPa.
Application example
According to the application example, the effects of the extract prepared in the embodiment 1 of the invention on clearing heat, dispelling wind, clearing lung, detoxifying, expelling pathogenic factors, tonifying spleen, eliminating dampness, relieving cough, reducing sputum and the like are researched through group comparison investigation.
In this application example, 300 persons were randomly invited to the experiment, and 300 persons were divided into 3 groups of 100 persons on average. The first group provides one dose of the product twice a day for each person, and each dose is one gram of the product; a second group provides twice daily, two doses per person, one gram of the product per dose; the third group provides the product twice a day for each person, three doses each time, and one gram of the product; for four weeks, the effects of clearing heat, dispelling wind, clearing lung, removing toxic substances, expelling pathogenic factors, removing dirt, invigorating spleen, eliminating dampness, relieving cough and reducing sputum of all experimental participants were investigated once a week, and the investigation results are shown in fig. 1.
Referring to fig. 1, ninety percent of the persons participating in the experiment considered that the product has better effects in clearing heat and dispersing wind, clearing lung and detoxifying, expelling pathogenic factors and removing dirt, strengthening spleen and eliminating dampness, relieving cough and reducing sputum, and the like, wherein the second group has the highest satisfaction degree in four surveys, that is, each person provides twice a day, two doses each time, and the administration mode of one gram of the product is the most economical and the best effect.
