I just learned about homeopathic medicine.
I thought that this was some sort of alternative natural approach to medicine, using traditional herbs and that kinda stuff. Sounds pretty OK, as long as you're careful.
Boy, was I wrong.
Here's Wikipedia's quick summary:
"Homeopathic practitioners contend that an ill person can be treated using a substance that can produce, in a healthy person, symptoms similar to those of the illness. According to homeopaths, serial dilution, with shaking between each dilution, removes the toxic effects of the remedy while the qualities of the substance are retained by the diluent (water, sugar, or alcohol). The end product is often so diluted that materially it is indistinguishable from pure water, sugar or alcohol."
So, apparently, homeopathic medicines are produced by taking a small amount of something that can produce symptoms similar to the illness itself and then diluting it hundreds of times so that the final product doesn't actually contain any of what you started with.
Homeopathic "medicines" are marketed with dilution numbers, such as 30x or 200K or some such. A 200K dilution means that a 1% solution has been diluted 1:100 two hundred times. That means that the final solution contains (1/100)^200 of whatever amount you start with. That's a number with four hundred zeroes after the decimal point before you get to a real number.
Read that again and let it sink in.
This is absolutely bats*** f***ing insane. What the hell kind of thought process would actually lead anyone to think that this kind of BS would actually do anything!?
