Sweet tea is the main folk drink in Guangxi. According to domestic research, sweet tea in Guangxi is non-toxic and has the effects of anti-oxidation, anti allergy, lowering blood pressure and blood lipids. Sweet tea has obvious effects on hypertension, cardiovascular and cerebrovascular diseases, obesity, coronary heart disease and arthritis. It can be used by obese and hypertensive patients to reduce weight, fat and blood pressure, especially for diabetic patients. In recent years, sweet tea has been popular in Japan, Europe, the United States, the Middle East and other international markets, and has been used in developed coastal areas of China. It is predicted that with the improvement of people's living standards and the enhancement of health awareness, sweet tea will become another conventional leading consumer of health food, with large market consumption and promising prospects.

    Sweet tea was discovered as a drug in China in the early 1980s. However, sweet tea has been used in folk for a long time. It is often used to replace sugar to process food. As a folk medicine, it is used to tonify the kidney and reduce blood pressure. It is known as divine tea and is as famous as Momordica grosvenorii. This is mainly because sweet tea is rich in steatoside, which is a diterpene sugar body, similar to stevioside in chemical structure. They are all composed of the same aglycones. The difference between the two is that only one molecule of glucose is added to the ten carbon of steatoside. The sweetness of sweet tea glycoside is 300 times of sucrose, and its calorific value is only 5% of sucrose. It is a natural sweet substance with high sweetness and low heat energy. Sweet tea glycosides can activate human insulin, synthesize blood sugar, and have a good health care effect on patients with diabetes and kidney deficiency. The sweet tea glycosides extracted from sweet tea have the best taste among sweet plants. Because of their green nature, health care and low heat, they show good economic value in food, beverage, cold food products, condiments, pharmaceutical industry, beauty cosmetics and other industries.

    Sweet tea glycoside also has the effect of preventing and treating dental caries. Streptococcus mutans is currently recognized as the most important oral cariogenic bacteria in the medical community. Its cariogenic mechanism is that it directly adheres, then ferments the residue of carbohydrates in the oral cavity in a short time to produce acid that rapidly corrodes the tooth surface, and produces glucose based transferase during metabolism to synthesize water-soluble glucan, which promotes the bacteria to adhere to the tooth surface to form dental plaque, prevents the diffusion of acid substances, and forms demineralization caries on the tooth surface. Because of its antibacterial, anti-inflammatory, hypoglycemic, blood lipid regulating and adjuvant treatment of diabetes, it can be used as a safe and effective natural extract to replace the current fluoride. It avoids the problems of poor stability of fluoride concentration in traditional fluoride treatment methods, fluoride resistance of oral bacteria after long-term use, and chronic poisoning of users caused by excessive fluoride.

    From the above, we can know that drinking sweet tea has many benefits and strengthens the protection of its active ingredientsrubusoside It also has a good prospect.
