Patturns ~ This isn't a good medical description, but what the Castor Oil pack did for me was to "soak" or "suck" the pain from and associated with my right ovary. That bugger has troubled me for years and one year, I got tired of it and applied the packs for about a week straight. After that, I never had problems with it for a long time. The packs can be used for a mulititude of reasons, many of which are covered in some of his books. If I can think of it tonight when I get home, I'll flip thru a few pages and refresh my memory and give a better description here. The packs can be ordered presoaked (I think) or you can order the wool pads and oil separately which I did...more economical I'm sure. It's really messy though. OH, and I just remembered...you have to use a heating pad on top of the pack to warm it into your skin. My very unscientific mind equates this to "soaking" the toxins out.
