Personally, I think it's better to drink some formal tea in winter. The general slimming tea is processed and added with some drugs. Drinking tea often is good for health but slow to take effect, so it should be drunk for a long time. Drink some cooked tea to nourish the stomach in winter, which belongs to warm tea and has no harm to the body. Moreover, it has the effect of losing weight and can get rid of greasy food. At first, Pu 'er tea was drunk in Tibet, where people had to deal with beef and mutton every day. It can also prevent constipation.
