Camphor in Belly Button
Once every several months, I experience hemorrhoids. I don't really know why as nothing changes in my diet or exercise. Usually the problem goes away in a few days. But the last time, I had more than one hemorrhoid appear and they did not go away quickly. I tried the castor oil remedy, and it was soothing, but did not resolve the problem. Then I read a comment on mercola.com, in which the person quoted Dr. Donald Carrow (now deceased, but a holistic MD).
Per Dr. Carrow, put camphor oil into the naval and the hemorrhoids would go away.
I didn't have straight camphor oil, so used metholatum rub which has the camphor. After one or two applications of the salve into my navel, I was back to normal! The hemorrhoids were gone. I don't know how it worked, but it did, so I wanted to pass it on for others who might like to try it.
