It would help a lot if popular alternative treatments were studied thoroughly (including testing on big numbers of human volunteers - every person who chooses to exercise their right to deny conventional treatment should be convinced to contribute by letting scientists observe him while he is treated alternatively) with intention to identify and dissect every humble positive effect they might cause in any particular kind of patients. A statement like "there is no credible evidence that thing helps" really can't convince an alternative treatment enthusiast to give his idea up. "Obiviously" there is no evidence because nobody no scientist for it. We need to be able to tell them honestly: "we have tried hard, hundreds different people were studied thoroughly for this particular treatment, it really doesn't help or only helps slightly a particular kind of patients you don't fit, please go and get treated the way proven efficient".
