I have seen Song Yifu's lecture on resveratrol, and introduced the protective effect of resveratrol on cardiovascular and cerebrovascular diseases. It has certain antipyretic and analgesic activities, but I have never said that resveratrol can treat lumbago and leg pain. If there are diseases that can't be treated in regular hospitals, resveratrol alone will definitely not work. It is good for treating many diseases, but it does not mean that resveratrol can cure all diseases. You should read the advertisement completely. Resveratrol may be some reasons.
