I read that cayenne pepper could alleviate excruciating pain of arthritis that I had in two fingers on my left hand. I'd awaken daily in pain to find my pinky and ring finger locked in a bent position and it would hurt very much to straighten. I would run hot water over them and it would get worse as weeks went on. I had been playing the piano several hours daily and most likely was the cause of this very painful arthritis, a common piano players ailment that if left unchecked would end my piano playing and use of two fingers. My fingers were dying it seemed. I met several ex-piano players who had exactly the same symptoms and quit playing because of the pain. Anyway, after reading Edgar Cayce's remedies with topical use of Castor Oil I thought it would be good to mix the Cayenne Pepper with Castor Oil so the mixture would stick to my fingers. So before bedtime, I'd take a paper hand towel and cut it to about 10x6 inches, wet it and squeeze excess water out until just very damp, then fold it to 10x2 (triple thick); now I'd mix some cayenne into some castor oil until very orangey/red and smear it on the first four inches (to cover both sides of fingers) of the paper towel and also smear some on my fingers; then I'd wrap my fingers with this bandage and excess paper, and finally a rubber band not too tight holding it all together. Every night I'd do this and take it off in the morning and there was noticeable reduction in pain immediately first day and more use of my fingers and after three months I was 80% normal and within nine months I was completely healed.
I'm 74 have arthritis in my shoulder-can't afford the creams, when I found out the main ingreatent was the same as cayenne pepper, I stared buying hot sauce that is made from aged cayennes, rub it on my shoulder couple times a day, it stains your clothing, but sure helps, and it is a lot cheaper.
