I wrote to you regarding the red worms and kidney pain down the page when we talked about flukes, go read that and the rash is different than I have had, mine itched and had water then blood come out of them. Borax is a soap in the laundry section at the stores, I would add some baking soda or just use baking soda.
As far as seeing some real progress with parasites, it depends on how infested you are and what your diet is like, depends on many things actually. I didn't see any large worms until three months cleansing, 12 to 15 inches long ones. Just keep cleansing, it is all a waiting game, but you are the winner at the end of this game
