I had color resection surgery and my colon/intestines were literally frozen post surgery. I had constipation from hell for about three months, then I went for accupuncture to see if I could get things moving...and the doctor reccomended I try Colosan powder. OMG! What a relief! I drank 1 teaspoon at night in a full glass of water with a juice of one lemon as a chaser. I went about 4 times. Easy BM, no strain, no pushing, no effort, no diarhea, just a normal stool. Then I drank same thing in the morning on an empty stomach. Got to work, had another bm. Also normal, no effort no loose stools. This stuff WORKS.
