Drinking guava leaf tea properly can help us absorb nutrients from tea and dredge the stomach, thus achieving the effect of losing weight. But it is unscientific to drink guava leaf tea for a long time to lose weight. Long-term drinking will produce dependence, and it is not a slimming drug or a panacea for losing weight. Excessive drinking may also lead to stomach problems. Guava leaves are rich in vitamin C, which can protect cells, enhance leukocyte activity, facilitate iron absorption, accelerate wound healing, maintain skin elasticity and moisture, whiten and prevent aging, and inhibit melanin production. Drinking guava tea properly at ordinary times still has the effects of beauty and skin care, detoxification and self-cultivation. It is recommended to drink 2-3 times a week.
