One of the main reason I write on this subject is that I have quite a few friends constantly in an out at some doctor and they rarely get any answers, only drugs and more tests. And they never seem to notice this, which I find quite amazing.
And speaking of other remedies, popular remedies, I've once had someone tell me to be very careful with chamomille tea, as it could be very dangerous. She must have read that somewhere, no doubt. Actually, not a day passes without finding an article warning about natural remedies. Whatever is cheap is, by default, useless, old wives' tales, quack science, as you say...
