Ibogaine

A powerful and physically demanding psychoactive with deep cultural roots in the Bwiti religious rites of Gabon, where the iboga root bark serves as a sacrament, and a history of use in psychotherapy for surfacing and reliving early memories, as well as experimental use against heroin dependency. Reports describe it as a rough journey in both body and mind, marked by intense anxiety and apprehension, an unfamiliar mood, dark-only visual hallucinations (dancing blue disks), bodily sensory disturbances, and autonomic signs like dry mouth, sweating, and raised pulse.
