When Dr Gerson arrived at the German post surgical recovery hospital in 1914 he noted that the soldiers were connected to "colonic buckets” He was concerned when he saw nurses pouring coffee into the enema buckets. He question the head nurse about the procedure and she said, "We don’t have any morphine"
She said so long as there is coffee in the bucket the soldiers have no pain. Immediately, Dr Gerson asked the soldiers if they had pain. They said we have no pain as long as there is coffee in the bucket.
Decades later scientists discovered that the liver controls pain (reason still unknown) is able to break down cancer tumors to be discharged from the human body (Dr Gonzalez, NY) and the active chemical ingredients in coffee, for liver, cleansing were later identified.
The Gerson clinic is still in operation in Mexico and now is operated by Dr Gerson aged, but very dynamic, daughter.
Dr Gerson published many books about his cancer protocols.
Today colonics is elevated to a herbal science now that herbal combinations in tea can replace water or coffee.
