A comprehensive guide to ibogaine’s healing power, cultural roots, and clinical potential • Explores how ibogaine works, including how it boosts cellular function, increases neuroplasticity, and interrupts habitual behavior patterns and trauma • Discusses the ritual roots of iboga in the Bwiti spiritual tradition of Gabon • Shares case studies showing ibogaine’s healing effects for addiction recovery, traumatic brain injury (TBI), and Parkinson’s The root bark of iboga is revered and stewarded by practitioners of the Bwiti spiritual tradition of Gabon. International expert Jonathan Dickinson explores how ibogaine, the primary active alkaloid found in iboga, is now emerging as one of the most promising tools for combating not only addiction, but also neurological injury and disease. Grounded in fieldwork and over 15 years of clinical observation, Dickinson discusses the roots of ibogaine as a tool of ritual spirituality in both the traditional and modern contexts. Considering the subjective states that ibogaine produces in the mind, he hypothesizes that ibogaine induces a “bicameral state.” This is a liminal mode of being in which ancient voices, archetypes, and internal guidance systems emerge, often catalyzing profound reorganization of memory, identity, and behavior. Exploring the potential of ibogaine in addiction recovery and neuro-regenerative medicine, the author examines how ibogaine can alleviate opioid withdrawal symptoms and minimize cravings afterward. He details how it boosts cellular function and increases neuroplasticity, and shares impressive case studies to demonstrate how ibogaine has successfully treated traumatic brain injury (TBI), Parkinson’s, neuropathic pain, and multiple sclerosis. This guide offers not only a deeper understanding of this transformational psychedelic medicine, but a new framework for engaging with the complexity and therapeutic potential of altered states of consciousness.
