I saw Cao Qinghua's advertisement on TV. Is Cao Qinghua really effective?

Advertisements on TV all say that they can only be broadcast after approval, which of course has a certain effect. Of course, effectiveness is also a corresponding condition for disease symptoms. If used in the treatment of rheumatic diseases, the effect is still trustworthy. However, it should be noted that everyone's physique is different, and the effect problem must be distinguished. Affected by many factors, it is correct to use it correctly.
