An ethanolic extract of Mimosa tenuiflora root bark, used in a psychedelic drink called 'jurema wine' in Indigenous Brazilian rituals, was analyzed for chemical composition and acute oral toxicity. Thirteen compounds were identified, including proanthocyanidins, alkaloids, a flavonol, and a dihydrochalcone. In female Swiss mice, single oral doses of 300 and 2000 mg/kg caused no deaths, no changes in food intake or body weight, and the lethal dose 50 (LD50) exceeded 2000 mg/kg, placing the extract in GHS category 5. However, both doses significantly altered relative kidney weights, hematological and biochemical parameters, and caused histopathological changes in the heart, liver, and kidneys, indicating acute oral toxicity.
