This sure sounds interesting to me since I am right now in bed suffering from a severe sciatic problem. I am seeing a chiropractor and my xrays show that my skeletal structure is in very bad shape - and the chiropractor HAS been helping - my pain is down to 4 or 5 from 8 or 9 when I went for my first treatment last week so I feel it is a good thing to continue seeing him but I am interested in trying this.
I guess you can get castor oil at a health food store - I've never used it and I don't even know what it is made of. I think I better start googling.
