There is a chapter in that book discussing the uses of DMSO and scleroderma.
I bought mine on Amazon.com. I have used DMSO successfully in treating aches and pains. I did not read this chapter, but I remembered seeing it because my brother's mother-in-law died of scleroderma. The doctor's were not able to help her in any way. I wish I had knew of this book way back then. My advice would be to try every natural method there is for improving the immune system. It seems that so little is known about scleroderma. If your efforts produce a cure you would be able to help others. You should also read Dr. Clark's book, The Cure For All Diseases .
I don't believe that she mentions scleroderma specifically, but her advice is based on good common sense.
