I asked Dr Fry about this. He said with Protomyzoa Rehumatica and Lyme he has tested some who have the protozoa and are not sick. The difference is the immune system. If our immune system was working correctly we would coexist with the organisms with little effect. The key is coexisting. I havent asked him about Dr Ty treatment lately, but did tell him about it. He found it intriguing and said it may be worth a try.
I did 3 years of antibiotics and antimalarial herbs. Did well toward the end. I felt being vegan and addressing my immune system was a big part of my improvement. Now I'm doing herbals and detox for mold and heavy metals. There is an order for detox and even though I'm in a flare - I think I have made gains in the right direction.
