Intestinal Worm Parasite With Black Matchhead "Head" and Blue Morgellons Like Thread. Based on the high number of parasites I have viewed thru microscope, and subsiding of skin erruptions since starting med treatments/cleansings, I think there is a clear connection of morgellons to gut parasites - perhaps THE cause. Others have noted this, and important for Morgellons sufferers to focus on inside-out cures. Albendezole (Valbazen) and 99.5% Praziquantel powder are cost effectively available through vet supply and fish supply stores in USA. World of difference although cure and die off fatigue and time frames a new challenge.
