Homeopathy is Bunk.

Yes, I'm not going to soft-soap it. Homeopathy is bunk. bollocks. built on stupidity. 

In the 1800s one Samuel Hahnamann came up with the idea that if a substance taken internally at regular strength caused certain symptoms, and if giving that substance in lesser, diluted forms caused lesser symptoms, then diluting it until there couldn't possibly be any more of the substance in the solution -- so that there was a negative amount of substance in the solution -- must then cure those symptoms. To this he added in the mumbo jumbo of praying over the water and slapping the bottle of solution being mixed against a leather bound book -- usually but not always a copy of the christian bible. The resulting stew of pseudoscience he passed on to his followers, who keep at it to this day, diluting stuff in water, alcohol or glycerin, sometimes dropping drops of it on sugar pills, and then selling the resultant useless crap for big sums of money. Because of placebo effect, and a phenomenon known as "regression to the mean" or because human beings sometimes get well on their own, People allow themselves to be deluded into thinking the stuff works, when in fact, it is only water, alcohol, glycerin or sugar pills. Entertainer and renowned skeptic James Randi has often challenged homeopaths to bring him a "fatal overdose" of Homeopathic sleeping pills, which he takes entire boxes of without ill effect (other than perhaps on his blood sugar.)

I am also reminded of the statement made by comedian Tim Minchin, who has said "if a vial of water can remember the memory of one drop of onion juice why doesn't it remember all the poo that's been in it ?"
One of these days I'm going to have to look for some quality research on why this stuff (and other weird quack treatments) persist in the face of overwhelming scientific evidence to the contrary.
Somehow, I suspect it will be for similar reasons to why people continue to subscribe to damnedfool ideas like flat earth, geocentrism and young earth creationism.
