[0002] Modern civilization has brought unprecedented convenience to people, but it has also brought air pollution, noise pollution, chemicals, electromagnetic radiation and more psychological pressure than ever before. More mental work means less physical work, and less exercise, coupled with the increasing pollution of various food additives, pesticides and air pollution, people generally have sub-health problems, and more and more toxins will accumulate in the body, eventually leading to a decline in body immunity. Exogenous and endogenous toxins remain in the body, which can block the Qi and hinder the normal operation of Qi and blood, consume Qi and hurt body fluids, destroy the normal functions of the internal organs and the mutual growth, restriction and coordination between the internal organs, and eventually cause imbalance of yin and yang and cause diseases. The most common ones are fever, acne, dark skin, rosacea, etc., and they are also accompanied by bad breath, obesity, constipation, etc., which seriously endanger human health. With the improvement of people's living standards, people are paying more and more attention to health. This attention is not only about the treatment after illness, but also pays more attention to the disease prevention and health care functions of daily life.

[0003] Traditional Chinese medicine originated in China and has a more complex composition than Western medicine. In the long-term practice of traditional Chinese medicine, many traditional Chinese medicines have been tested by practice and accepted by modern medicine. Tea has a long history in China and is an indispensable drink in people's lives. It is loved by people both at home and in the workplace.

[0073] The raw materials, dosages and preparation methods of this comparative example are exactly the same as those of Example 1, except that no seabuckthorn fruit is added in this comparative example.

[0074] Experimental Example 1

[0075] The heat-clearing and detoxifying green brick tea in the examples and comparative examples of the present invention was selected as a test sample to conduct an evaluation test on the inflammatory effect on mice.

[0076] Experimental items and methods: The results of each experiment were expressed as, and the differences between groups were analyzed by t test. P < 0.05 was used as the significant limit value for the test, and p < 0.01 was used as the extremely significant limit value for the test. All statistical analyses were performed using SPSS software package.

[0077] Xylene-induced ear inflammation test in mice

[0078] 70 Kunming mice, weighing 18-22g, half male and half female, were randomly divided into 7 groups, including a blank control group, embodiments 1-4 and comparative examples 1-2, with a total of 6 tea-filling groups. In addition to normal feeding, the blank control group was gavaged with physiological saline, and the other groups were gavaged with the corresponding heat-clearing and detoxifying tea, which was continuously gavaged once a day, with an equal volume of 0.1ml / 10g each time. After the last administration, 0.06ml of xylene was applied to the right auricle of the mice in each group, and the left side was not applied as a control. The mice were killed 0.5h after inflammation, and the ears were cut off along the auricle baseline. The discs of the same part of the left and right ears were punched with a 7mm diameter puncher, and weighed on an analytical balance. The anti-inflammatory effect of the heat-clearing and detoxifying tea was evaluated by the auricle swelling inhibition rate. Auricle swelling inhibition rate = (the difference between the average weight of the two ears in the blank control group-the difference between the average weight of the two ears in the tea-filling group) / the difference between the average weight of the two ears in the blank control group × 100%. The results are shown in Table 1.

[0079] Table 1. The results of inhibition of xylene-induced ear swelling in mice in each group

[0080]

[0081]

[0082] It can be seen from Table 1 that the heat-clearing and detoxifying tea prepared by Examples 1-4 of the present application has a good inhibitory effect on the swelling of the auricle of mice caused by p-xylene. Although the heat-clearing and detoxifying tea prepared by the traditional tea-making method in Comparative Example 1 is the same as that in Example 1 in terms of raw materials and dosage, its inhibition rate is significantly lower than that of Examples 1-4, indicating that compared with the traditional tea-making method, the heat-clearing and detoxifying tea prepared by the present application as freeze-dried powder can better exert its heat-clearing and detoxifying effect and can more effectively release the effective ingredients therein. The raw materials of Comparative Example 2 are exactly the same as those of Example 1, except that seabuckthorn fruit is not added, and its inhibitory effect is significantly lower than that of Example 1 without adding seabuckthorn fruit, indicating that seabuckthorn fruit can play a synergistic role with Artemisia selengensis, lotus leaf, purslane, and Lobelia in the raw materials.

[0083] Experimental Example 2

[0084] Rat cotton ball granuloma test

[0085] 70 healthy SDwistar rats, weighing 140-160g, half male and half female, were randomly divided into 7 groups, including blank control group, Examples 1-4 and Comparative Examples 1-2, totaling 6 tea-irrigation groups. In addition to normal feeding, the blank control group was intragastrically administered with distilled water every day, and the other groups were intragastrically administered with the corresponding heat-clearing and detoxifying tea, continuously intragastrically, once a day, and each time an equal volume of 10ml / kg·d was given. Each group of rats was anesthetized with ketamine hydrochloride (0.1g / kg, ip), the left and right groins were trimmed, disinfected with iodine, deiodinated with 75% alcohol, a small incision was made on each side, the subcutaneous tissue was expanded with a vascular clamp, a sterilized cotton ball (20mg, containing 160U of penicillin and 0.1mg of streptomycin) was buried on each side, and the skin was sutured. Starting from the day of surgery, rats in the drug administration group began to be gavaged with the drug once a day for 7 consecutive days. On the 8th day, the animals were killed by cervical dislocation, the cotton balls were taken out, the adipose tissue was removed, and the rats were dried in an oven at 60°C. The rats were weighed and the granuloma weight was obtained by subtracting the original cotton ball weight. The granuloma inhibition rate was calculated as (average net weight of granulomas in the blank control group - average net weight of granulomas in the drug administration group) / average net weight of granulomas in the blank control group × 100%. The calculation results are shown in Table 2.

[0086] Table 2 Effects of each group on the proliferation of cotton ball granuloma in rats

[0087] Group Granuloma inhibition rate Example 1 67.42％ Example 2 68.12％ Example 3 67.37％ Example 4 69.54％ Comparative Example 1 54.98％ Comparative Example 2 41.95％ Blank control group —

[0088] It can be seen from Table 2 that its effect on the proliferation of cotton ball granuloma in rats corresponds to the experimental results of Experimental Example 1, which further proves that compared with the traditional tea making process, the method of making the heat-clearing and detoxifying tea into freeze-dried powder in the present application can retain more effective ingredients therein, and its heat-clearing and detoxifying effect is better; sea buckthorn fruit can play a synergistic role with the raw materials of Artemisia selengensis, lotus leaf, purslane and Lobelia, so that its heat-clearing and detoxifying effect is better.

[0089] Effect example
