Clinical verdict
Diatomaceous earth is a silica powder with zero clinical evidence for any marketed claim (detox, parasites, cholesterol). CRITICAL SAFETY: food-grade DE (amorphous silica) ≠ pool/industrial-grade DE (crystalline silica = carcinogen/silicosis). Even food-grade DE should NOT be inhaled — respiratory irritation risk. The 'parasite cleanse' claim is based on DE's use as an insecticide (physical abrasion of insect exoskeletons) extrapolated to intestinal parasites without ANY evidence [1].
