Condition
Intestinal Parasite Infection
An intestinal parasite infection happens when single-celled organisms like Giardia or worms like roundworm and hookworm settle in the digestive tract, often causing diarrhea, cramping, bloating, and nutrient loss. Oregano oil has the only trial reviewed here: people's parasite counts improved, and the evidence is limited. That study was tiny, with just 13 participants, so it cannot show how well oregano works, and other supplements like probiotics and berberine have no findings to report yet.
