I need to add that a 'live blood' analysist suggested suspended copper as a remedy for the parasites. 7 days on, 7 days rest and another 7 days taking the copper along with zinc also suspended in water. A friend did this who had a type of parasite he could actually see crawling under the skin on his arms. The only info I've found so far with a 'google' is using copper for parasites in fish tanks.
