They're amazing. If I ever start feeling sick, this helps more than anything.
Caffeine and palmitates (chemicals in coffee) work synergistically to stimulate and cleanse the liver and blood. Without entering the digestive tract the caffeine is absorbed through the bowel wall, via blood vessels, and makes its way directly to the liver.
The caffeine exposure causes the liver’s portal veins and the bile ducts to expand which increases the release of diluted toxic bile. The enema fluid triggers peristalsis (intestinal muscle contractions) and the efficient removal of wastes from the body.
Palmitates in the coffee stimulate and increase the production of a liver enzyme called glutathione-S-transferase (GST) wikipedia.org, which removes free radicals and cancer cells from the bloodstream and facilitates detoxification of the liver. As a result of the enema the liver becomes less congested with debris, which makes room for the filtering process of yet more bodily toxins.
