Toxicity Profile

Route of Exposure

Oral (ingestion) (2) ; dermal (2)

Mechanism of Toxicity

The 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)

Uses/Sources

Djenkolic acid is a plant toxin found in the beans of the South-East Asian legumes jengkol (Archidendron jiringa). (1)

Minimum Risk Level

Not Available

Health Effects

Djenkolic acid is nephrotoxic to humans. (1)

Symptoms

Symptoms 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)

Treatment

Treatment for djenkolic acid poisoning requires hydration to increase urine flow and alkalinization of urine by sodium bicarbonate. (1)
