Faith in medicine
If I have faith in a medicine I take it, and if not, I do not.
This is irrespective of whether said medicine is government or doctor approved.
I don't rate either's approval very highly.
I give more weight to the opinion of a serious naturopath who has demonstrated clearly their knowledge in the area in question.
Research and a clear mind for discriminating between PR and truth is what is needed to sort the wheat from the chaff.
That and personal experience!
