More seriously, to what extent do homeopathic remedies work because the users believe they will work? Psychosomatic effects?
If you mean placebo effects, don't they apply to each and every medicine?
If you are really serious about finding out more, I am the wrong person to ask and you won't believe me anyway. I suggest finding some literature on it, and one to start with would be NASA scientist Amy Lansky's "Impossible Cure". Really a good read.
