I was getting a rash doing these packs, right on the place where I did the packs on my lower back, was fairly nasty and lasted 3 weeks. So I stopped doing them and investigated rashes. Turns out that doing the castor oil packs releases lots of toxins and you need to wash the castor oil (and toxins) off the skin after the pack is finished. I just done three in 4 days, drank some olive oil after the third pack and no rashes whatsoever. My BM have also become darker which is sign that I am digesting more of my food, my liver/gallbladder are producing more bile to digest the food I eat. I think this is a good sign that these packs work for me.
