Arsenic Poisoning
Arsenic poisoning happens when inorganic arsenic, often from contaminated drinking water, builds up in the body and damages cells, causing skin lesions and raising the risk of cancer, heart disease, and diabetes. The evidence is strongest for charcoal, which limited how much arsenic the gut absorbed after acute poisoning, and moderate for NAC and selenium. Charcoal only applies to sudden exposure, and the evidence for antioxidants is thinner: curcumin raised antioxidant enzyme levels, but the evidence is limited.
