Description

Novel bagged tea for preventing coronavirus pneumonia and preparation method thereof

Technical Field

The invention relates to the technical field of health-care tea bag preparation, in particular to a novel coronavirus pneumonia prevention tea bag and a preparation method thereof.

Background

Coronaviruses are a large family of viruses known to cause the common cold and more serious diseases such as Middle East Respiratory Syndrome (MERS) and Severe Acute Respiratory Syndrome (SARS). The novel coronavirus is a new strain of coronavirus that has not been previously found in humans. People of all ages may be infected, mainly adults, of which the elderly and infirm and sick seem to be more susceptible, and children and pregnant women are also susceptible to pneumonia infected by the novel coronavirus. After people are infected with coronavirus, common signs comprise respiratory symptoms, fever, cough, shortness of breath, dyspnea and the like. In more severe cases, the infection can lead to pneumonia, severe acute respiratory syndrome, renal failure, and even death.

There is currently no specific treatment for diseases caused by the novel coronavirus. However, many symptoms are treatable and therefore need to be treated according to the clinical condition of the patient. In addition, the adjuvant care of infected persons can be very effective.

The third edition of diagnosis and treatment of pneumonia infected by the national novel coronavirus, NCP, is definitely in the category of epidemic diseases in traditional Chinese medicine, causes epidemic pestilence and is located in the lung, and basic pathogenesis is characterized by dampness, heat, toxicity and stasis. The Tong Xiaolin academy states that the epidemic should be distinguished from pestilence and pestilence, and belongs to the category of cold-dampness (pestilence). Pestilence and pestilence belong to yang disease in nature, the ending is yin impairment, and yin impairment is the main line. The disease is a yin disease, the ending is impairment of yang, and the impairment of yang is the main line. In therapeutic methods, cold and dampness are treated. For pathogenic cold being suppressed by pathogenic dampness, it is used to treat cold by means of pungent-warm exterior-releasing. For damp pathogen, it is fragrant and needs to avoid the filth and transform it into turbid. The epidemic situation shows that the symptoms of most patients are obviously improved after Chinese medicinal intervention treatment. For example, the traditional Chinese medicine composition can quickly improve the symptoms of patients in the aspect of treating mild symptoms, and has obvious improvement on fever reduction, cough reduction, sore throat, extreme inappetence and hypodynamia of the patients. The traditional Chinese medicine improves severe cough, chest distress, coarse breath and fever of severe patients, reduces the conversion of severe patients to critical diseases, and has higher conversion rate to common patients.

At present, chinese medicinal preventive formulas are published in a plurality of regions, for example, the Chinese medicinal preventive formula No. 1: 3g of rhizoma atractylodis, 5g of honeysuckle, 3g of dried orange peel, 2g of reed rhizome, 2g of mulberry leaf and 10g of raw astragalus; the traditional Chinese medicine for preventing the No. 2 prescription: 10g of raw astragalus, 10g of fried bighead atractylodes rhizome, 10g of divaricate saposhnikovia root, 6g of cyrtomium rhizome, 10g of honeysuckle flower, 10g of fortune eupatorium herb and 6g of tangerine peel; the internal prescription for preventing the novel coronavirus pneumonia: 10g of honeysuckle, 15g of reed rhizome, 15g of cogongrass rhizome, 10g of wrinkled gianthyssop herb, 6g of angelica dahurica and 6g of tsaoko amomum fruit. After the decoction is decocted, the decoction is large in amount, the traditional Chinese medicine is thick in taste, bitter and astringent in mouthfeel, the general acceptance degree is not high, and stomach discomfort is easily caused due to the bitter and astringent mouthfeel, and certain stimulation is generated more or less. It is not suitable for long-term administration in terms of taste and comfort.

Blank group: the bagged tea is not tried for 7 days.

Observation indexes are as follows: the physical condition of the subject (mainly fever) was followed for 7 days, and the prophylactic group and the blank group were subjected to nucleic acid detection of new coronary pneumonia after the end of the trial.

(4) Prevention of outcome

The body conditions (χ 2 values =4.234, p-bundle 0.05) were significantly different from those of the nucleic acid test (χ 2 values =4.518, p-bundle 0.05) in the preventive group compared to the blank group, and the results are shown in table 1. The number of people with fever and positive people detected by accounting in the prevention group is obviously lower than that of the blank group, and the tea bag provided by the invention has good effects on the prevention of fever and neocoronary pneumonia infection, can enhance the immunity of the organism, and plays a good role in prevention and health care.

Table 1: comparison of prevention Effect between groups

Experimental example 2

The inventors selected 700 patients with pulmonary discomfort, all between 20 and 60 years of age. The patients mainly show symptoms of cough with excessive phlegm, chest distress, short breath, unsmooth breathing and the like. During the test period, all patients stop taking other medicines and health care products, live normally, and take the prevention tea bag of the embodiment twice a day, one bag at a time, and the symptoms are relieved after taking the prevention tea bag for two weeks. The patients were divided into one group per 70 th, and the blank group was not taken, and the tea bags prepared in example 2 and comparative examples 1 to 9 were used. The results of the experiment are shown in table 2:

table 2: symptom-improving application effects of different formulas

As can be seen from Table 2, the improvement effect was significantly different from that of the blank group except for the control example 7. Example 2 the best results, all patients improved symptoms; the comparison examples 1-9 obviously improved the number of people, and the number of ineffective people was increased; the control examples 5 and 7 have diarrhea adverse reactions. Experimental data show that the control examples 5 and 6 respectively lack poria cocos and phaseolus calcaratus have poor improvement effects, which shows that the poria cocos and the phaseolus calcaratus in the formula play a main prevention role, and compared with the control example 7 which lacks the poria cocos and the phaseolus calcaratus, the control example 7 has the worst improvement effect, which shows that the compatibility and combination of the poria cocos and the phaseolus calcaratus in the formula are particularly critical, the two are lack of one and can not be used, and the poria cocos prevents diarrhea after being taken in the formula; the improvement effect is slightly improved corresponding to the comparison examples 1 and 2 which lack honeysuckle and ginseng respectively, which shows that the honeysuckle and the ginseng play secondary roles in the formula; the improvement effects of the corresponding agastache rugosus and lily control examples 3 and 4 are slightly reduced, which shows that the agastache rugosus and the lily plays an auxiliary role in the prevention of the formula; the improvement effect of the tea bag is poor in comparison example 8 and comparison example 9 in which the raw medicinal materials are directly mixed and packaged, wherein the powder is placed under a 50-mesh screen, and the improvement effect of the product is influenced by the granularity of the medicinal materials.

Experimental example 3 evaluation of taste

The tea bags of example 2 and comparative examples 1, 2 and 6 were placed in 500ml glass cups, respectively, and brewed with 300ml boiling water for 5min, and tasted when the temperature dropped to 35 ± 5 ℃, and the taste and smell of different tea bags were compared and scored, and the results are shown in table 3.

Table 3: taste evaluation results

Grading standard: the rate is preferably-4, more preferably-3, usually-2, and much less preferably-1.

As can be seen from Table 3, the taste scores of the bagged tea of example 2 are all higher than those of the comparative examples 1, 2 and 6, wherein the honeysuckle is absent in the comparative example 1, and the faint scent taste is absent; in contrast 2, the ginseng lacks of ginseng, the fragrance and the taste of the ginseng cannot be reflected, and the effect of promoting the production of body fluid is weakened, so the fragrance is little, and the aftertaste is sweet and weak; in comparative example 6, the lack of red beans did not sufficiently correct the sweetness, and the overall sweetness was slightly weak. The tea bag prepared by the raw material formula of the invention is proved to have better taste and more delicate fragrance, and is a tea bag with good taste and smell.

EXAMPLE 4 Water soluble substance determination test

The tea bags prepared in the embodiment 2 and the comparative examples 8-9 are put into a 500ml conical flask, added with 300ml of boiling water and soaked for 5 minutes, the water solution is poured out, added with 300ml of boiling water and soaked for 5 minutes again, the solution is filtered, the tea bag residues are taken out and dried at constant temperature, and weighed. The water extract content was calculated and the results are shown in table 4 below.

Table 4: measurement of Water-soluble substance

As can be seen from Table 4, the water extract content of the teabag of example 2 is higher than that of the comparative examples 8-9 and 7% -12%, and the water extract content of the comparative example 8 is slightly weaker than that of the example because the raw medicinal materials which are not crushed are dissolved out after being soaked and taken; the water-soluble dissolution rate of the tea bag prepared by the formula is only 13%, and the water-soluble dissolution rate is obviously less than that of each example because the particle size is too fine, the specific surface area of the medicinal powder is too large, the adsorption effect is enhanced, and the diffusion is influenced, so that water-soluble substances are not easy to dissolve out, and the particle size of the powder has influence on the dissolution effect of the water-soluble substances.

The invention is not limited to only that described in the specification and embodiments, and thus additional advantages and modifications will readily occur to those skilled in the art, and it is not intended to be limited to the specific details, representative embodiments, and examples shown herein without departing from the spirit and scope of the general concept as defined by the appended claims and their equivalents.
