[0044] In specific examples, studies have shown that astragalus is more effective than traditional treatments for diabetic nephropathy, cerebral thrombosis, and heart failure, with significant results. In summary, astragalus is more effective than traditional treatments for cardiovascular, nervous, and circulatory system diseases, with significant results.

[0045] Astragalus polysaccharides can significantly enhance immune cell activity and comprehensively improve the body's disease resistance. In an experiment on immunocompromised mice, intervention with astragalus polysaccharides increased the mice's lymphocyte proliferation by 70% compared to the control group, and natural killer cell (NK cell) activity increased by 55%, demonstrating its potent boosting effect on cellular immunity. The experiment also found that astragalus polysaccharides increased the levels of immunoglobulins IgG, IgA, and IgM in mouse serum by 40%, 35%, and 30%, respectively, significantly improving humoral immune function.

[0046] Astragalus flavonoids possess potent free radical scavenging properties and can effectively mitigate myocardial ischemia-reperfusion injury. In animal experiments, intravenous injections of astragalus flavonoid extracts in canine models of coronary heart disease revealed a 38% reduction in myocardial infarction size, a 42% decrease in myocardial malondialdehyde (MDA) content, and a 50% increase in superoxide dismutase (SOD) activity in the experimental group compared to the control group. This suggests that astragalus flavonoids can significantly enhance myocardial antioxidant defenses, reduce lipid peroxidation damage, and protect myocardial cells.

[0047] Astragalus polysaccharides can effectively improve insulin resistance and regulate glucose metabolism. In a study of streptozotocin-induced diabetic rats, eight weeks of oral administration of astragalus polysaccharides showed a 32% decrease in fasting blood glucose levels compared to the model group, a 35% decrease in the area under the curve of the oral glucose tolerance test (OGTT), and a 48% increase in the insulin sensitivity index. This suggests that astragalus polysaccharides enhance insulin sensitivity and promote glucose uptake and utilization in peripheral tissues, thereby exerting a beneficial hypoglycemic effect.

[0048] Astragalus polysaccharides have a significant inhibitory effect on various tumor cells. In vitro experiments have shown that astragalus polysaccharides can inhibit the proliferation of HepG2 liver cancer cells by 65% ​​within 48 hours. They also induce apoptosis in tumor cells by activating apoptosis-related proteins such as Caspase-3, with an apoptosis rate of up to 40%. In vivo experiments in tumor-bearing mice showed that after intervention with astragalus polysaccharides, the growth rate of tumor volume in mice was significantly slowed, with a tumor inhibition rate of 45%. Furthermore, when combined with the chemotherapy drug cisplatin, the anti-tumor effect of cisplatin was enhanced by 30%, while also reducing the damage to the mice's weight and immune function caused by cisplatin.

[0049] In specific examples, studies have shown that lotus leaf extract has a strong inhibitory effect on breast cancer cells and exhibits strong cytotoxicity against various tumor cells, including KB and MCF-7. Animal experiments have also demonstrated that both raw and charcoaled lotus leaves exhibit hemostatic effects. Lotus leaves also have anti-malarial, anti-inflammatory, and anti-allergic effects. Therefore, lotus leaves can clear away heat and summer heat, reduce lipids and weight, and act as a diuretic and reduce swelling, making them suitable for those seeking to clear heat and summer heat, and alleviate edema.

[0050] Lotus leaf extract exhibits potent anti-tumor activity. In an in vitro study on breast cancer cells (MCF-7), lotus leaf alkaloids inhibited cell viability by 70% after 48 hours of exposure. They also induced cell cycle arrest at the G0 / G1 phase, reducing the proportion of cells entering the proliferative phase by 45%. Furthermore, they upregulated the expression of the pro-apoptotic protein Bax and downregulated the anti-apoptotic protein Bcl-2, inducing apoptosis to a rate of 35%. Similar results were observed in experiments on KB cells, with cell viability inhibition reaching 75% after 72 hours.

[0051] Both raw and charcoal-processed lotus leaves can effectively shorten clotting time and reduce inflammatory responses. Animal experiments have shown that administering a lotus leaf decoction to mice reduced bleeding and clotting times by 35% and 40%, respectively. In a xylene-induced ear swelling and inflammation model, lotus leaf extract reduced ear swelling by 50% and decreased the levels of inflammatory mediators such as prostaglandin E2 (PGE2) and tumor necrosis factor-α (TNF-α) in inflamed tissue by 42% and 48%, respectively, demonstrating its significant anti-inflammatory effects.

[0052] In a specific embodiment, Dendrobium officinale, also known as black knot grass, belongs to the genus Dendrobium of the Orchidaceae family, is a perennial epiphytic herb of the Orchidaceae family, and is a precious wild medicinal plant.

[0053] Dendrobium polysaccharides can significantly increase saliva secretion and improve symptoms of dry mouth and thirst in animals with Yin deficiency. In mice with thyroxine-induced Yin deficiency, oral administration of Dendrobium polysaccharides for 14 days showed a 60% increase in saliva secretion compared to the model group. Water intake decreased by 38%, and plasma aldosterone levels decreased by 42%. This suggests that Dendrobium polysaccharides regulate the neuroendocrine system, promoting salivary gland secretion and alleviating fluid deficiency caused by Yin deficiency. It can also effectively enhance the immune function of immunocompromised mice. Experiments showed that administration of Dendrobium polysaccharides to immunocompromised mice induced by cyclophosphamide increased the T lymphocyte transformation rate by 75% compared to the model group. The levels of immunoregulatory factors such as interleukin-2 (IL-2) and interferon-γ (IFN-γ) in the serum increased by 50% and 60%, respectively. The phagocytic rate and phagocytic index of chicken red blood cells by macrophages increased by 48% and 55%, respectively, comprehensively enhancing both cellular and humoral immunity. Dendrobium officinale extract has a significant anti-fatigue effect. In a swimming experiment with mice, those given the extract lasted 65% longer than the control group. Post-exercise serum lactate levels decreased by 45%, and blood urea nitrogen levels decreased by 38%. Glycogen reserves in the liver and muscles increased by 50% and 42%, respectively. This suggests that the extract effectively alleviates physical fatigue by increasing energy reserves and reducing the production and accumulation of exercise-induced fatigue substances.

[0054] In specific embodiments, studies have shown that roses contain a variety of physiologically active ingredients, with volatile oils being considered their primary active ingredients. Volatile oil compounds primarily include linalool, citronellol, 3-methylhexane, 4,5-dimethyloctane, and 2-methylheptane. These compounds have the effects of aromatically invigorating the senses, promoting blood circulation and qi, dilating the cardiovascular system, and improving visceral and peripheral blood circulation. Roses also contain flavonoids, organic acids, tannins, and other chemical components, which have hypoglycemic, anti-tumor, antibacterial, antioxidant, liver-soothing, depression-relieving, blood circulation-regulating, and menstrual regulation, helping to alleviate emotional stress and improve sleep quality.

[0055] Its volatile oil components (such as linalool) can effectively regulate neurotransmitter levels and improve emotional behavior. In a rat model of depression induced by chronic unpredictable mild stress (CUMS), four weeks after oral administration of rose volatile oil, the rats' preference for sugar water increased from 40% in the model group to 65%, their forced swimming immobility time was shortened by 48%, and the levels of serotonin (5-HT) and norepinephrine (NE) in the hippocampus increased by 45% and 50%, respectively. This indicates that rose volatile oil exerts its antidepressant effects by regulating the monoamine neurotransmitter system.

[0056] Flavonoids can significantly improve cardiovascular function and reduce oxidative stress damage. In an atherosclerosis model rabbit experiment, administration of rose flavonoid extract reduced serum total cholesterol (TC), triglycerides (TG), and low-density lipoprotein cholesterol (LDL-C) levels by 35%, 42%, and 40%, respectively, while increasing high-density lipoprotein cholesterol (HDL-C) levels by 50%. Simultaneously, serum malondialdehyde (MDA) levels decreased by 48%, while superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities increased by 55% and 60%, respectively. This reduced endothelial cell damage and inhibited the formation of atherosclerotic plaques.

[0057] Rose has an inhibitory effect on a variety of pathogens. In vitro antibacterial experiments showed that the minimum inhibitory concentration (MIC) of rose extract against Escherichia coli and Staphylococcus aureus was 60 mg / mL and 55 mg / mL, respectively. At these concentrations, bacterial growth was significantly inhibited, with inhibition zone diameters reaching 18 mm and 20 mm, respectively.

[0058] In a specific embodiment, lentil flower is cold in nature and sweet in taste, and has the effects of strengthening the spleen and harmonizing the middle, relieving heat and dampness, stopping diarrhea, and stopping leukorrhea. It can be used for vomiting and diarrhea due to heat and dampness, vomiting and retching due to spleen deficiency, poor appetite and long-term diarrhea, red and white vaginal discharge, water retention and thirst, dysentery, and infantile malnutrition. Modern pharmacological research shows that lentil flower tea can treat bacterial dysentery, etc.

[0059] A decoction of lentil flowers has a significant therapeutic effect on bacillary dysentery. In a Shigella-infected mouse model of bacillary dysentery, five days of oral administration of a decoction reduced diarrheal episodes by 65% ​​compared to the model group, reduced the number of Shigella in feces by 80%, significantly alleviated colonic tissue pathological damage, and decreased the expression levels of the inflammatory factors IL-1β, IL-6, and TNF-α by 50%, 55%, and 60%, respectively. This suggests that the decoction exerts its antidiarrheal effect by inhibiting pathogen growth and alleviating intestinal inflammation.

[0060] In a specific embodiment, studies have shown that patchouli volatile oil reduces gastric acid secretion and has a weaker effect on increasing pepsin activity than water extracts and deoiled water extracts. Patchouli perfume-soluble components (deoiled water extracts) can significantly promote digestive juice secretion and enhance gastrointestinal digestive function. In a functional dyspepsia model rat experiment, after seven days of oral administration of deoiled patchouli water extract, the rats' gastric juice secretion increased by 55% compared with the model group, and gastric acid concentration and pepsin activity increased by 42% and 50%, respectively. At the same time, the rats' absorption rate of nutrients increased by 40%, and their body weight gradually returned to normal, indicating that it can effectively improve dyspepsia symptoms. In a senna leaf-induced diarrhea model in mice, after administration of patchouli perfume extract, the number of diarrhea episodes in mice was reduced by 60% compared with the model group, and the duration of diarrhea was shortened by 55%. In the glacial acetic acid-induced writhing experiment in mice, patchouli extract can reduce the number of writhing times by 50% and prolong the writhing latency by 45%, indicating that it exerts anti-diarrhea effect by inhibiting excessive intestinal peristalsis and reducing intestinal inflammation, and has a significant inhibitory effect on visceral pain.

[0061] In specific examples, studies have shown that the chemical component content of jujube is positively correlated with drug efficacy, and differences in chemical component content can provide a basis for differences in drug efficacy. Jujube has a wide range of pharmacological effects, including blood-tonifying and anticoagulant, antioxidant, anti-fatigue, anti-inflammatory and antibacterial. Jujube polysaccharides can significantly increase the hemoglobin content of anemia model animals and inhibit platelet aggregation. In an experiment on rats with iron-deficiency anemia, after four weeks of oral administration of jujube polysaccharides, the rats' hemoglobin content increased by 38% compared to the model group, their red blood cell count increased by 35%, and their serum iron content increased by 42%. In an in vitro platelet aggregation experiment, jujube polysaccharides reduced the adenosine diphosphate (ADP)-induced platelet aggregation rate by 60%, indicating that they exert their blood-tonifying and anticoagulant effects by promoting hematopoietic function and regulating the blood coagulation system.

[0062] In specific embodiment, research shows, Chinese medicine liquorice has certain influence on aspects such as antulcer, antispasmodic, antiviral, anti-AIDS, varicella-zoster virus, antiallergic, antitussive and expectorant. Glycyrrhizic acid can promote gastric ulcer healing by strengthening gastric mucosal barrier function. In rat gastric ulcer model experiment, after giving glycyrrhizic acid gavage treatment for 4 weeks, rat gastric ulcer healing rate reached 75%, prostaglandin E2 (PGE2) content increased by 60% in gastric mucosal tissue, gastric mucosal blood flow improved by 55%, MDA content reduced by 48% in gastric mucosa simultaneously, SOD activity enhanced by 50%, alleviated gastric mucosal oxidative stress injury, promoted ulcer surface repair. In the mouse cough model induced by ammonia, after giving liquorice decoction, mouse cough incubation period prolonged by 65%, and cough frequency reduced by 60%. In the tracheal phenol red excretion experiment, licorice water decoction can increase the tracheal phenol red excretion of mice by 55%, indicating that it can inhibit the cough reflex center, promote respiratory mucus secretion, and dilute sputum, thereby exerting antitussive and expectorant effects.

[0063] In a specific embodiment, studies have shown that ginger has the effect of warming yang and removing blood stasis, can improve cold and damp constitution, promote blood circulation, and ginger also has certain effects on anti-inflammatory, antibacterial, antioxidant, antiemetic, hypoglycemic, and protection of gastric mucosa. Ginger volatile oil components (such as zingerone) have a significant inhibitory effect on vomiting caused by chemotherapy drugs. In a cisplatin-induced pigeon vomiting model experiment, after giving ginger volatile oil gavage, the number of pigeon vomiting times was reduced by 70% compared with the model group, and the vomiting latency was extended by 65%. In a clinical study, a group control test was carried out on tumor patients receiving chemotherapy. The vomiting incidence rate of the experimental group of patients chewing ginger slices was reduced by 45% compared with the control group, and the degree of nausea was significantly alleviated, indicating that ginger volatile oil can inhibit the vomiting reflex arc by regulating gastrointestinal neurotransmitters and receptors, and play an antiemetic effect. Ginger can effectively dilate blood vessels and improve blood circulation. In an experiment on rats with a cold-stagnation and blood stasis model, after administration of ginger extract, the skin temperature of the rats' limbs increased by 1.5°C compared with the model group, and blood rheology indicators such as whole blood viscosity, plasma viscosity and red blood cell aggregation index decreased by 35%, 40% and 42% respectively. At the same time, the thromboxane B2 (TXB2) content in the rat serum decreased by 48%, and the 6-keto-prostaglandin F1α (6-keto-PGF1α) content increased by 50%, which regulated the balance of vasoactive substances, promoted blood circulation, and improved the cold-stagnation and blood stasis state.

[0064] In the embodiment, the prepared health tea bag is brewed 1-2 times a day, 1 bag each time, and boiled water is used as tea, which is suitable for the elderly, middle-aged and young.

[0065] Experimental Example 1:

[0066] Twenty 40-day-old mice were divided into four groups, numbered as experimental groups 1 to 4;

[0067] The compositions described in Examples 1 to 2 and Comparative Examples 1 to 2 were dissolved in warm water to obtain solutions. The solutions of Example 1 (test group 1), Example 2 (test group 2), Comparative Example 1 (test group 3), and Comparative Example 2 (test group 4) were gavaged into the mice of Test Groups 1 to 4; the gavage volume was 0.2 mL / 10 g / d based on the body weight of the mice, and the gavage was continued for 20 days. During the experiment, the mice in each test group had free access to food and water.

[0068] After 20 days of continuous gavage, the appearance, coat color, food intake, drinking water, urination and defecation of mice in each group were normal, and their growth and development were in good condition. No obvious behavioral changes or poisoning changes were observed. The mice in each group were killed and dissected, and the main organs such as heart, liver, spleen, lung, and kidney of each group of mice were observed. The results showed that no abnormal phenomena such as enlargement, atrophy, and necrosis of the organs were found, indicating that the test substance had no adverse effects on the growth and development of the body.

[0069] Therefore, the compositions described in Examples 1 and 2 and Comparative Examples 1 and 2 are safe.

[0070] Experimental Example 2:

[0071] Ten cyclophosphamide-induced immunocompromised mice were randomly divided into two groups: a control group and a drug-treated group. Five normal mice were taken as the normal group.

[0072] Normal group: Oral administration of normal saline.

[0073] Control group: Oral administration of normal saline.

[0074] Drug-administered group: Oral administration of the composition solution of Example 1 (0.2 mL / 10 g / d) for 15 consecutive days.

[0075] Detection indicators: T lymphocyte transformation rate, serum IL-2 content.

[0076] result:

[0077] T lymphocyte transformation rate (%) IL-2 (pg / mL) Normal group 85.2±3.5 45.6±4.2 control group 48.7±5.1# 22.3±3.8# Drug administration group 82.1±4.3* 42.5±3.9*

[0078] *Note: #Compared with the normal group, P<0.01; *Compared with the model group, P<0.01.

[0079] As can be seen from the table, the T lymphocyte transformation rate and serum IL-2 content of the drug-treated group are close to those of the normal group, which has the effect of improving immunity.

[0080] Experimental Example 3:

[0081] Ten mice with diarrhea induced by senna leaves were randomly divided into two groups: a control group and a drug-treated group.

[0082] Control group: Oral administration of normal saline.

[0083] Treatment group: Example 1 health tea solution gavage (0.2mL / 10g / d), 7 consecutive days

[0084] Detection indicators: number of diarrhea episodes in 24 hours and duration of diarrhea.

[0085] result:

[0086] Diarrhea frequency (times / 24h) Duration (h) control group 12.5±2.1 48.7±6.2 Drug administration group 4.8±1.3* 22.3±3.5*

[0087] *Note: *Compared with the control group, P<0.01.

[0088] As can be seen from the table, the number and duration of diarrhea in the drug-treated group were significantly shorter than those in the control group, so it has an anti-diarrhea effect.

[0089] In summary, this tea bag has significant health benefits for people who work under high-pressure environments for a long time, often stay up late, have irregular diets, have low immunity, and need to regulate their qi deficiency and improve their mood.
