let's talk about homeopathy. look at this movie first:

i think homeopathy is not only not valid, but also no good and it should be illegal and banned by law - those people use other's misfortune and play on card of sick people's vulnerability to turn profit for themselves by giving them false hopes. all known "homeopathic" effects can actually be attributed to placebo effect. i am shocked that scientific community doesn't judge and fight against this phenomena and by that protects general population from being ripped off by this con-artists.
my advice - stay away from homeopathic medicine. it won't do u harm, but it won't do you good (if u don't take into account placebo which can btw be achieved by cheaper means). i would see it as benign phenomena if they wouldn't charge immensely their services, this thing is call a fraud in criminal law.
