Castor oil is suppose to be real good for rubbing into swollen lymph glands too, to help release toxins. I was doing that for a bit, it may have helped a tad but I am going to try this method of a couple hours a day a few times a week and see how it goes. The glands on the right side of my neck have been slightly swollen since January or late Dec. Whether it's mercury locked in there or a reaction to plastic filling material from one of the dentists, because it started with the work on that tooth, I'm not sure.
