Will they ever find a cure for gain greene?

listen up. hyperbaric oxygen has been used for Gang Green (go Jets), I mean gangrene.And many years ago my dad had gangrene and they wanted to cut off the legs below the knee. I read this book by the Shute brothers in Canada. They are doctors and they recommended vitamin E for increasing blood circulation. I gave my dad 1000 IU a day and in a week the circulation returned and the gangrene reversed with minimal skin damage.
