Principle:
1. Coffee contains caffeine. Caffeine can combine with antidiuretic hormone secreted by hypothalamus, which will prevent the secretion of antidiuretic hormone in human body, and antidiuretic hormone can enhance the reabsorption of water by renal tubules and collecting ducts. After the antidiuretic hormone is antagonized by caffeine in black coffee, it will have diuretic effect, which can expel excess water from the body at the same time, so it will remove edema.
In addition, coffee also contains a certain amount of cocoa, which also has a certain diuretic effect.
3. From the point of view of traditional Chinese medicine, coffee is pungent and warm, which can dispel dampness and warm can help yang, so it can help kidney yang to diuresis, improve urination, and improve abdominal distension and edema. Its effect is similar to that of Cistanche deserticola isothermal Chinese medicine, so modern Chinese medicine combined with coffee (daily drinking) has a better effect on damp-heat dysentery or damp-heat prostatic hyperplasia.
