Well, CJAZ has his quack pseudosciences mixed up. The links are to herbal remedies, not homeopathic ones. It's entirely possible for herbal stuff to have effects and side-effects. After all, most "conventional" drugs are just purified or slightly modified herbal products.
Although, of course, most of the herbal stuff sold on line is basically placebo. The weird thing though, is that placebos work for a lot of people.
So do "nocebos." People convince themselves that some arbitrary thing is going to make them sick or give them an allergic reaction... and it does whether or not it is actually in whatever you feed them. They only have to think that they're consuming it.
There is a lot of mental attitude involved in health and sickness that we don't really understand. Probably starting off the day with a good wank and a bit of self affirmation - or self hypnosis, whatever - is not a bad thing.
I was horrified at the long lists of prescriptions that my parents would bring home from the VA. When I was counting out my Mom's pills, there were like 20 of them at a time, that changed every time she was hospitalized. But most of them turned out to be nutritional supplements. Things she could easily have got over the counter. I don't know if the doctors didn't trust her to shop for them on her own, or if it was just to get them on the "benefits" instead of "out-of-pocket" list. Stuff like that probably inflates the count of prescriptions.
