Epazote
土荆芥 · Tǔ Jīng Jiè
Anti-parasitic herb with serious toxicity risks
What it does
Epazote was historically used as a powerful anti-parasitic for hookworms, roundworms, and pinworms. In TCM, it dispels wind, eliminates dampness, and treats topical itchy skin. Modern medicine has effectively retired it due to extreme toxicity. Mexican kitchens still use small amounts of fresh leaves as a culinary herb.
How to take it
Medicinal use is largely obsolete. Fresh leaves are used in small amounts in Mexican cooking (1–2 leaves per pot of beans). Avoid concentrated extracts entirely.
For cooking, add a sprig of fresh epazote to bean dishes. Avoid medicinal use
Cook with beans, soups, and quesadillas. Helps mute beany flavor and aid digestion. Use sparingly.
Drop one fresh epazote leaf into a pot of cooking black beans

Where it comes from
Epazote (Chenopodium ambrosioides) is native to Central and South America and naturalized across Asia. Its essential oil, ascaridole, was the basis of mainstream anti-parasitic drugs in early 20th-century medicine. Reports of fatal poisoning, especially in children, ended its medical use. The fresh herb remains a Mexican kitchen staple, especially with black beans, where small amounts add a unique flavor.
