I would tend to think that any negative result from taking herbs is probably salicylate allergy and a subsequent liver backup on detoxification. I don't believe in scattering at this point. parasites are going to be throughout the body in cysts so just because you notice them in places you haven't before doesn't mean they were not there already. Heck practically no one feels parasites until they start killing them anyway. Incredibly well designed critters. It is helpful when you realize that the reason any pharma drug was designed was so that it could be patented. Once you realize that you may loose faith in the pharma system.
