Hi folks,
Two small cent's worth:
1. This very morning someone was talking to me about using some Castor Oil as a patch.
It didn't work.
Reason: the junk sold as "oils" in supermarkets bears very little resemblance to the natural thing - it's like "salt". With any oils for cooking or other uses, only use *cold-pressed* virgin oils. It WILL cost a lot more, but the difference in taste/efficacy shows at once.

Here is an interesting Site to help avoid the "Dr Jon" problem:
