Its drinking functions of promoting digestion, invigorating stomach, killing fishy smell, reducing blood fat and weight, lowering blood pressure and blood sugar, and promoting fluid production to keep out the cold are incomparable to other teas. Especially for people who lack vegetables and fruits, drinking Fuzheng tea for a long time can not only supplement the vitamins and minerals needed by the human body, but also help digestion, eliminate food stagnation, regulate the stomach, relieve constipation and diuresis, regulate human metabolism, and play a certain role in health care and case prevention.
