I'm using one from a company called Vaxa that comes with 2 bottles of Parasitin for parasites (and includes L-Arginine and L-Orthinine)1 bottle of Colon-aid to take in the evenings for elimination, and 1 bottle of Reflora to restore healthy bacteria. These products have homeopathic ingredients, as well. I know other people are using other products, but I decided to try this one and see how it works.
