In ancient China, the application of lotus leaf in dietotherapy and medicine has long been recorded, and there are famous traditional delicacies such as roast duck and roast chicken with lotus leaf. The food wrapped in lotus leaves not only has its own taste, but also reveals a faint lotus leaf fragrance, which is crisp outside and tender inside, oily but not greasy. In fact, lotus leaf is mainly used to help obese patients with edema lose weight, and it is not effective for everyone. However, lotus leaf is mild in medicinal properties. Drinking lotus leaf tea often can strengthen the spleen and eliminate dampness, cool blood and stop bleeding, and induce diuresis, which is of great benefit to the body.
