Opium
"Colon Cancer forced removal of entire colon except 7.5 cm at rectum. J-Pouch constructed from Small Intestine to work as colon but small storage means frequent diarrhea. Drs. prescribed 1.0 ml Tincture 3 times a day to slow this. 
Four years later taking 0.5 ml 3 times daily. This treatment very successful. Side effects now beginning to show on legs and ankles in form of circulatory (vein) collapses. 
So short term, awesome medicine. Long term...we shall see."
