The reason this tea works is because it is KILLING OFF THE parasites THAT ARE CAUSING THE COLON PROBLEMS... Hippocrates says that DEATH BEGINS IN THE COLON, and Yerba Mate kills off the parasites. It is also important to do a Colon Cleanse called Triphala and a major cleanse twice a year. A good one is Paragone...
The real problem as to why you have parasites are VITAMIN/MINERAL deficiencies....particularly zinc... You need a HIGH PROTEIN DIET BECAUSE ZINC helps keep parasites at bay...as well as other minerals... Optizinc is the best one to use because it has to be pared with the right amount of copper. YOU find ZINC in meat!!!
