Key Takeaway
Food-grade diatomaceous earth is used in pet deworming, garden pest control, and some human natural health protocols. Only food-grade DE should be used internally, and inhalation of the dust should be avoided.
Why This Matters
Diatomaceous earth consists of microscopic silica shells whose sharp structure is believed to damage the exoskeletons of insects and possibly some intestinal worms. It is widely used in gardens and barns to control pests and in some natural pet care routines as a dewormer. Human use is more controversial: some people take small amounts of food-grade DE internally for gut and parasite support, though clinical evidence in humans is limited. Pool-grade DE is chemically treated and should never be taken internally.
