Do roses, hawthorn, cassia seeds, lemons, lotus leaves and red dates have the effect of losing weight in boiling water? After drinking for a few days, I began to be constipated. Excessive drinking is harmful to my health. Cassia seed and hawthorn together have the effect of reducing fat, while small roses and lotus leaves alone have the effect of reducing fat, and the combination of the two does not conflict. However, it is recommended not to drink too much and too strong every day, and a small amount can be used for a long time. Lotus leaves are cold. It is recommended to add it while it is hot. If the stomach is not good, it is recommended not to add too much or not.
