Oolong tea can reduce fat and thus lose weight. Cassia seed is a good medicine to eliminate constipation, which is very suitable if you are obese. But if you lose weight on an empty stomach, I suggest that you can also drink this, which can speed up your metabolism.

Guiding opinions:

Cassia seed (1/2 tablespoons), lemon (cut into one slice) and hawthorn (2 slices) {Don't eat hawthorn because it will scratch your stomach if you have a bad stomach} Cassia seed and hawthorn are sold in Chinese medicine shops and lemon supermarkets. Methods: Put them into the cup, rinse them with boiling water and cover the cup. You can drink it in five minutes.
