Mr B, if you have found a Chinese practitioner whom you trust, then go and get some treatment from him/her. If thousands of years of experience shows that something works, then it doesn't matter that Scientific Method hasn't yet explained how it works. Isaac Newton made a famous comment about being like a boy playing on a beach while the great ocean of truth was undiscovered in front of him; we have waded some distance into that ocean since Newton's time, but there is still an awful lot that we don't understand, especially in medical science.
