Read about castor oil packs in a previous thread and have been reading all the info I can find on the interent. I just started using these for some lymph nodes in my left armpit. I've been doing them for about 3 nights now w a hot water bottle. Anyone have any experience w castor oil packs? Can I use them too much? Is there side effects. I'm not sure if the hot water bottle makes it warm enough. Would more heat be better? Also, read of someone mixing the oil w cayenne pepper but I'm sure that may sting especially in the armpit region. I think the nodes may have decreased in size a little. I'd love to hear what other things anyone has used them for? I also read about people using the oil on the face and it even helps reduce wrinkles.
