Synopsis

Source of validity: Traditional
Rating (out of 5): 1

Diatomaceous Earth (DE) is a naturally occurring, soft, siliceous sedimentary rock that can be crumbled into a fine white powder. Its use for treating or supporting the removal of parasites, including tapeworms, is primarily based in traditional and folk practices, particularly in the context of animal husbandry and natural health communities. DE is believed to work mechanically: its microscopic sharp edges are said to damage the exoskeletons of insects and possibly the outer layers of some internal parasites, leading to their dehydration and death. However, the scientific evidence supporting these claims, especially with respect to internal parasites like tapeworms in humans or animals, is minimal and largely anecdotal.

Most of the published research on DE focuses on its effectiveness as an external insecticide for pests such as fleas, bed bugs, and grain storage insects, not on internal parasites. There are a few animal studies suggesting some effect against certain gastrointestinal worms, but results are inconsistent and often not specific to tapeworms. No substantial clinical trials in humans have evaluated DE for tapeworm treatment. Major health agencies do not endorse its use for this purpose. Thus, while traditional use exists and some animal data are suggestive, the overall quality and quantity of evidence is low, meriting a rating of 1.
