You should watch the James Randi videos on youtube debunking homeopathy...
4 rules of homeopathy :
1) Prooving: Take a substance and give it to a "well person" and note the effects.
2) Patient walks in to the doc's and has symtpoms corresponding to those effects - so you give them that substance diluted
3) Dilution: Take 1 part of substance, and dilute in 10 parts of water then "shake not stir". Take 1 part of the diluted mix and recommence... 19 more times
4) The more you dilute it - the more powerful it is
Oh, and remember Avogadro's number: After point 4 gets to 24 repeat dilutions, you have 1 chance in 10 of finding 1 molecule or atom in the mixture and some go up to 1500 dilutions - the equivalent of 1 grain of rice diluted in a sphere of water the size of the solar system with the sun in the center and pluto at the edge... then diluted 2 000 000 000 times...
