So I dont know what to think. Perhaps it's worth a try, but I know Andy Cutler does not think it's wise to do with mercury toxicity. maybe ok for other illnesses, but there seems to be a problem when its done with mercury poisoning (not sure why, I'll try and find that out).
Hulda Clarke herself also warns about liver cleanses during mercury toxicity, if i don't remember incorectly. Anyway, she says its most important to do a parasite cleanse first, then a kidney cleanse, and THEN a liver cleanse.
