Colonblow ingredients:
the powder = psyllium, with stevia sweetener and natural plant flavors.
the capsules = cascara sagrada bark, fig, prune, senna leaf, cascara sagrada extract, senna extract, magnesium sulfate
Cascara and senna are cathartic laxatives .. basically they act by irritating the intestine, increasing the strength of the contractions which moves the contents along more quickly
. Senna also pulls water from the walls of the intestine, thus keeping the stool softer.
Magnesium sulfate = epsom salts, which also pulls water from the intestinal wall into the stool to make it looser.
FWIW, digestive juices and pancreatic secretions in the small intestine are green. The pigments are normally reabsorbed in the colon, however a strong laxative will zoom things along before any proper absorption can take place. This is likely the cause of the green stools reported by someone earlier in the thread.
This product is just a combination of psyllium fiber with a strong laxative, nothing more.
