Homeopathic medicine "is a form of alternative medicine, first expounded by German physician Samuel Hahnemann in 1796, that treats patients with heavily diluted preparations which are thought to cause effects similar to the symptoms presented." (http://en.wikipedia.org/wiki/Homeopathy). I saw the mock video below on the skeptics blog, http://skepticblog.org/, and thought it was so amusing I had to post it here. I've known people who swear by this stuff, which is unfortunate. Treatments like these, that don't work, are dangerous and can actually kill people by diverting them from legitimate treatment. A good analysis of this is at http://www.csicop.org/si/9709/park.html.
The video, however, is quite amusing.
