I totally agree with that parasitologist. The parasite is the vector for most ALL diseases and infections internally. Quite intentionally I believe, but that's a whole other conversation.
My opinion is I believe you need to do a herbal cleanse which has Wormwood in it, and a zapper. Dr. Clark felt the zapper and one of her other recommended herbs, Black-Walnut hull would do the trick to kill any of the infections.
I'm just too impatient and found an herb that was more targeted and worked faster. So take some olive leaf extract (I use 3 or 4 capsule every 4 or so hours) for the fungal (Candida) part. And persist with all three until your symptoms clear, is how I would do it. Remember to take at least hot water with the herbs, but a cayenne capsule would be best, if your body tolerates heat well.
