i·bo·ga·ine (ĭ-bōgə-ēn′, -ĭn)
An alkaloid drug, C20H26N2O, that acts as a dopamine blocker and mitigates symptoms of withdrawal from various psychoactive drugs, including heroin and cocaine. Ibogaine is used to treat drug addiction in some countries, including Canada, but is illegal in the United States.
[French ibogaïne, from New Latin (Tabernanthē) iboga, species name of shrub in whose root it is found, probably ultimately from Ghetsogho (Bantu language of Gabon) ibogha; akin to boghaga, to cure.]
