Djenkol Bean: The Pungent Seed With a Kidney Warning
Djenkol Bean · ลูกเนียง · Archidendron jiringa
Djenkol Bean — ลูกเนียง (luk-niang) — Archidendron jiringa.
Crack open the flat spiral pod and the seed hits with a garlicky sulfur reek that clears a room, the smell southern Thais chase when they eat the young beans raw beside nam prik. The bean is reportedly a source of protein, fiber, thiamin, and riboflavin, and the part on your plate is the seed kernel — eaten young and raw, or boiled hard until the smell settles. Djenkol is southern Thailand's most notorious bean — a garlicky, sulfur reek and a real caution to match. It is rich in djenkolic acid, a natural compound that can form sharp crystals in your kidneys; eat too many, above all raw, and it can trigger stabbing back pain and even kidney damage. Boiling softens the smell but not the risk, so keep to small portions of well-cooked beans and drink plenty of water. Follow Longevity Biome for a new Thai plant every day.

Research context
Djenkol's blood-sugar drop was seen only in diabetic rats, where the same feeding also harmed healthy organs; the bean people eat carries djenkolic acid and a real toxicity risk — J Sci Food Agric, 2011
