I have made a personal choice to stay away from 'conventional, western' medicine. I feel the prescriptions can harm the immune system and don't target all the parasites and bacteria. I have used tinctures before, and have just finished my first course of Humaworm. I have researched a lot in the 6 months I believe I have had parasites. I have come to the conclusion that Humaworm is the best way to go. I will be doing a liver flush tomorrow and then taking humaworm in 90 days.
