It is often used to replace sucrose 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 Siraitia grosvenorii. The steatoside rich in sweet tea is a diterpene sugar body, which is similar to stevioside in chemical structure. They are all composed of the same aglycone. The difference between them is only that there is one molecule of glucose on the ten carbon of steatoside. The sweetness of sweet tea glycoside is 300 times that 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 extract powder can activate human insulin and blood sugar. It has a good health function for patients with diabetes and kidney deficiency.
