"unless there is clear evidence of benefit" - who and to whom has to show this in your opinion? (I pay my homeopathy bills myself, of course, and the remedies I get for free from a homeopath in the States whom I have not even personally met - so he was not able to "touch" the patient and all the rest that Mr. Goldacre in his writings implies is a big source of the patient's improvement.

"And I am still concerned about possible harm, as in the example of vaccinations."

WHat do you mean by this?
