The Budwig Diet is very popular indeed in the alternative cancer world. It is stated that it has more than a 90% success rate for people suffering with cancer.
I can attest, that the first day I had a glass of flax seed oil and cottage cheese (along with some blueberries to give it some taste) I had a massive Herxheimer Reaction.
You can read about the diet here on this website. With a 90% success rate, why wouldn’t you give it a try?
