The Tapeworm could be either place. Many think the small intestine is preferred because of the nutrient rich contents. When I passed my 18" Tapeworm I assumed it came from the colon because I passed it after a vinegar enema. However, after doing the parasite cleanse plus some P&B colon cleansing I passed three feet of mucoid plaque studded with red and white round worms and did not see any sign of a tapeworm. The old Curezone adage "Better out than in" probably applies here, you need to get rid of the Tapeworm regardless of where it calls home.
