I don't know if it pulls mercury, but definitely know it pulls something(metal) out. When I started it on your advice Neomi, I had that old familiar overwhelmed with yeast reaction. Which to me means heavy metals in my system. I have the same reaction with cilantro and dmsa. I get very thrush-y? and feel just yucky slimey. Oh yeah, I wheeze also. Also my sweat smells like metal. I don't know for a fact that's what all this means, but strange how all the feelings and symptoms are the same as when I was doing IV EDTA chelation. Kinda like experience being the best teacher here I suppose. HTH
