You may want to research Linus Pauling. He ascribes to the theory that high doses of vitamin C cures many ailments. In his book, How to Live Longer and Feel Better, he says “vitamin C acts similarly to aspirin in inhibiting the synthesis of some prostaglandins” (prostaglandins are a group of lipids (fats) made at sites of tissue damage or infection that have actions similar to hormones and are involved in dealing with injury and illness).

There’s not a lot of info specifically in this book about auto immune diseases, but I did find that snippet. A fellow pede spoke of Dr. Pauling regarding a protocol for reversing artery blockage.
