castor oil packs-real treatment or quackery?

Hi, PD, your gallstones don`t seem to be attracting much attention, so I`ll focus there. Instead of waiting 3-4 years, how about a couple of weeks/months? A good friend of mine was given a naturopathic cure for them which, being a skeptic, I ridiculed. I was punished by a weekly visit from him toting a pickle bottle containing various sizes of stones--the latest he had passed. This went on for a few weeks until they tapered off. He shows no ill-effects from the treatment two years later. He`s on the road at present, but if you are interested, I`ll find out details.

Actually, Schraf, from the folks who brought us such noble cures as DDT and thalidomide, I would think regular science should have the grace to blush occasionally.

Gosh, PD, when I saw 'penetration enhancers', I thought you were-----never mind.

It`s medicine for sick plants. Or are you saying humans are the only ones that need cures? BTW, DDT is still in use in third world countries.
How many drugs have been pulled in the last decade because they aren`t safe? And of course, the real science defending nicotine continues.
