Toxicity Profile
Route of ExposureOral (ingestion) (2) ; dermal (2)
Mechanism of ToxicityThe toxicity of djenkolic acid in humans arises from its poor solubility under acidic conditions after consumption of the jenkol bean. The amino acid precipitates into crystals which cause mechanical irritation of the renal tubules and urinary tract. (1)
MetabolismNot Available

Lethal DoseNot Available
Carcinogenicity (IARC Classification)No indication of carcinogenicity to humans (not listed by IARC).
Uses/SourcesDjenkolic acid is a plant toxin found in the beans of the South-East Asian legumes jengkol (Archidendron jiringa). (1)
Minimum Risk LevelNot Available
Health EffectsDjenkolic acid is nephrotoxic to humans. (1)
SymptomsSymptoms of djenkolic acid poisoning include abdominal discomfort, loin pains, severe colic, nausea, vomiting, dysuria, gross hematuria, and oliguria. Urolithiasis can also happen, with djenkolic acid as the nucleus. In young children it has also been reported to produce painful swelling of the genitalia. (1)
TreatmentTreatment for djenkolic acid poisoning requires hydration to increase urine flow and alkalinization of urine by sodium bicarbonate. (1)
