The “hidden parasites” ad, checked

Short answer: no study has tested wormwood, black walnut or clove against parasites in a person. Wormwood has only been tried on parasites in laboratory dishes. The real facts the ad borrows — a Nobel Prize, a Bible verse, a roundworm’s egg count — are each about something else.

What the ad says

A 2026 Facebook ad posted under the name “Shelly Helston” is written as a retired funeral director’s story: 41 years, “over 9,000” bodies, “worms dug into the gut wall, sealed behind a gray film, in people whose doctors swore their tests were clean.” It describes a spouse with bloating, tiredness, 3am waking and brain fog, says ivermectin, fenbendazole and health-store cleanses each worked “for about three weeks”, and leads to a store selling Sanlava Organics “Wormwood Black Walnut Cloves (6600 mg) | Flush Out Hidden Parasites & Larva”, which says it “Targets Adults, Larvae & Eggs.” We read it on 2026-10-24. We can’t check the story; a story is not a study.

The borrowed facts

• “In 2015 it won a Nobel Prize in Medicine.” Half of the 2015 prize went to Tu Youyou for artemisinin, made from sweet wormwood (Artemisia annua) — a medicine for malaria, a blood parasite, not gut worms. The other half went to William Campbell and Satoshi Ōmura for avermectin, the parent of ivermectin, which came from a soil bacterium (Inside Science). Neither prize was for a wormwood supplement.
• “A plant named in the Bible seven times … tied to cleaning something rotten out of the body.” In scripture, wormwood is a picture of bitterness and judgment — “gall and wormwood” — not of cleansing (the verses).
• “One female of these lays up to 200,000 eggs a day.” True of the roundworm Ascaris (CDC), which is diagnosed with a stool test and cleared by prescription medicine in one to three days (CDC).
• “The test was never built to find them.” One stool test can miss parasites — which is why the CDC asks for three samples a few days apart (CDC).
