Iboga

Iboga is a Central African shrub in the family Apocynaceae whose root bark contains psychoactive alkaloids, especially ibogaine.

Updated August 1, 20261 min readCited sources

Iboga is a Central African shrub whose root bark contains psychoactive alkaloids, notably ibogaine, used in traditional ceremonies and studied for addiction treatment.

What it is

Iboga (Tabernanthe iboga) is a shrub native to Central West Africa in the Apocynaceae family. Its root bark is the main source of ibogaine and other psychoactive alkaloids. Traditional use includes spiritual and initiatory rituals, especially in Bwiti-related contexts.

Key details

Reported effects include visual distortions, euphoria, calm, and intense introspection. However, iboga and ibogaine carry serious risks, including cardiac complications. Ibogaine is controlled or illegal in many countries, including the United States (Schedule I), while Canada regulates its use in some clinics.

Why it matters

Ibogaine has been investigated for treating substance use disorders, particularly opioid dependence, with some studies showing reduced cravings and withdrawal symptoms. It is not an approved standard therapy in many countries, and safety concerns limit its medical use.

In short

  • Iboga is a shrub native to Central West Africa with psychoactive root bark.
  • Traditional use involves spiritual and initiatory ceremonies.
  • Ibogaine is studied for addiction treatment but has significant safety risks.
  • Legal status varies; it is restricted in many countries, including the US and Canada.
Canadian angle

Ibogaine is described by some sources as regulated in Canada rather than broadly legalized, and Canadian clinics have been mentioned in recent reporting on ibogaine treatment access.[3][8]
