I successfully used castor oil packs for Bells Palsy which my co- worker contracted. I was beginning to have double vision and my eyes were inflamed. I used the pack on both eyes one hour nightly for 3 nights but the directions called for 4 nights. Well, I got busy and didn't do the 4th night and the symptoms returned until I completed the 4 nights in a row...No more problem at all.
Also, for me the packs are a great pain reliever. I used just the castor oil right on my cheek when I had an infected tooth. Still had to go to a dentist but CO stopped the pain immediately!
Also, used it to remove a wart on my son's toe. Each night applied CO put a sock on him until the wart was gone which was less than a week.
