Basically, I am detoxing whatever heavy metals (mercury, lead, cadmium, arsenic etc.) toxicity I might have. In the past, I used Boyd Hailey's OSR#1 for 3 months and that cleared up my head a great deal. Right now, I am focusing on liver detox and I understand that high dose vitamin C detoxes heavy metals while glutathione (thio in it means sulfur) detoxes liver.
