beta-Carboline alkaloids harmine, harmaline, and tetrahydroharmine can stimulate the central nervous system by inhibiting the metabolism of amine neurotransmitters, or by direct interaction with specific receptors; they are found in numerous plants, including Peganum harmala, Passiflora incarnata and Banisteriopsis caapi, and in the entheogen preparation Ayahuasca, which is traditionally brewed using B. caapi to enhance the activity of amine hallucinogenic drugs. The ingestion of plant preparations containing beta-carboline alkaloids may result in toxic effects, namely visual and auditory hallucinations, locomotor ataxia, nausea, vomiting, confusion and agitation. We report a case of intoxication following intentional ingestion of P. harmala seed infusion; P. harmala seeds were bought over the Internet. The harmala alkaloids were identified by gas chromatography-mass spectrometry in the seed extract and the patient's urine. This is, to our knowledge, the first case of P. harmala intoxication corroborated by toxicological findings. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
