A powerful antioxidant you may have never heard of is working hard to keep every cell in your body safe from free radical damage and oxidative stress. That's a good thing because oxidative stress has been associated with more than 74 diseases and disorders.
This major cell protector and master antioxidant is glutathione. It is produce naturally in our cells if the required building blocks are available. Among its many functions, it strengthens the immune system, detoxifies the body, fight intracellular inflammation, and neutralizes numerous types of free radicals.

Coffee enemas are reported to increase glutathione levels up to eight times more than supplemental N-Acetyl Cysteine, a glutathione precursor which is commonly used to increase glutathione. Plus the coffee enemas help increase the body's natural glutathione production instead of just adding glutathione via glutathione supplements.
A million people in the grave who used coffee enemas? Where in the world do you get that figure, Bret? I should point out that no one I know of recommends only doing coffee enemas for cancer.
Coffee stimulates the glutathione-S-transferasean enzyme system in the liver, which results in a very large increase in gultathione production. The reason that rectal administration is best is that items administered rectally, such as therapeutic enemas, go directly to the liver via the hepatic portal vein system. Coffee also stimulates and dilates the bile duct. If the bile ducts are not open and flowing then the liver may have to endure too high a load of toxins from any successful anti-cancer protocol.
I suppose you could just drink the coffee, but it would take liters of coffee to come close to the same benefits.
