Has anyone used Miao medicine? It is said that it is very effective for rheumatism and bone pain. Is it true?

Miao medicine is extensive and profound, and many of them are secret recipes handed down from generation to generation. If you find someone else, it should be effective, but it is difficult to cure it radically. I suggest that another way to improve rheumatic bone pain is sand therapy, which has a very good effect on rheumatism, gout, arthritis, etc., and you can feel it basically once or twice. Pure physical therapy, be sure to do more! (Hope to adopt, thank you ~)
