Could you please help me out with some information, please. I want to do a parasite Cleanse, and looked at the site under the cleanse for Dr. Clark. It mentions Clarkia , but when I spoke to some people at Self Health, they said Clarkia is not Dr. Clark's product, that Dr. Clark does not have any products that she sells. So is Clarkia Dr. Clark's formula or someone else's? Also, is Clarkia the best parasite cleanse or is Paragone or some other one that someone mentioned -- Yurba Prima and someone mentioned a product by NowFoods.com. What is the best?
