Iboga and Bwiti Traditions

Cardiac risk first. Ibogaine, the best-known compound from iboga, has been linked to dangerous heart rhythm problems and sudden deaths. A toxicology review reported 27 fatalities after ibogaine ingestion. [1] NIDA notes that an analysis of studies from 2015 to 2020 associated ibogaine use with long QT syndrome, an electrical delay in the heartbeat. [2] If someone has taken iboga or ibogaine and has fainting, chest pain, a racing or irregular heartbeat, seizures or trouble breathing, call 911 (US) or local emergency services. US Poison Help is 1-800-222-1222 (poisoning: what to do first).

What iboga is

Iboga is the common name of Tabernanthe iboga, an accepted species name in the GBIF taxonomy database (read 2026-10-22). [3] It is a shrub of the lowland tropical forests of the Congo Basin, and its root bark contains several alkaloids, of which ibogaine is the best known. [4] Iboga (the plant and its traditional use) and ibogaine (one isolated compound) are not the same thing. See iboga vs ibogaine, the iboga plant profile and the ibogaine compound guide.

The Bwiti tradition

The Bwiti religious tradition of Gabon, Equatorial Guinea and southern Cameroon uses iboga. [4] A Chacruna Institute article, written for a general audience, describes iboga as a cultural keystone species, meaning one of exceptional significance to a people, and says it is integral to the Bwiti religion, practiced in Gabon and to a lesser extent in other Central African countries. [5] Bwiti is a living religion with its own communities, teachers and rules. This page leaves out ceremonies and initiation, which belong to the people who practice them.

Traditional use is not the same as a treatment

Iboga's role in Bwiti is religious and communal. It is not evidence that ibogaine treats addiction or any other condition. A pharmacology review describes how ibogaine was isolated, was sold for a time as an antidepressant in France until adverse effects led to its removal, and was later taken up by people who believed it cured opioid addiction. [6] See cultural description vs clinical endorsement.

What research shows about ibogaine (not about Bwiti)

Evidence labels: insufficient evidence (not enough to judge), preclinical (cells or animals only), evidence of harm.

• Veterans with brain injury: insufficient evidence. An open-label study (no control group) of 30 special operations veterans gave ibogaine together with magnesium. Disability, PTSD, depression and anxiety scores improved after one month, and the authors reported no unexpected or serious adverse events. They say controlled trials are needed. [7]
• Addiction treatment: insufficient evidence. Reviews describe ibogaine as an unlicensed treatment used outside approved care. [1] Proper evidence not found for a completed randomized trial in the sources read.
• Animal and cell findings: preclinical. Animal studies suggested ibogaine could blunt drug self-administration, and at high concentrations it is neurotoxic and cardiotoxic in laboratory work. [6] These findings should not be applied to people.

Risks

• Deaths. A forensic review of 19 deaths between 1.5 and 76 hours after ibogaine found that existing medical problems, mainly cardiovascular, or other substances explained or contributed to death in 12 of 14 cases with enough data. [8]
• Poison service data. Over ten years, the UK National Poisons Information Service received enquiries about seven patients; all had symptoms and six showed heart toxicity. [9]
• Medicine interactions. Differences in the CYP2D6 enzyme can change blood levels of ibogaine and its main product, which matters when other medicines use the same enzyme. [1] See medication interactions.
• Existing heart conditions. Reviewers warn that deaths are more likely in people with heart conditions and those taking other medicines. [1]
• Unsupervised plant products. The forensic review also named the uninformed use of plant-based forms as a risk factor. [8]

Nobody should treat addiction on their own with ibogaine or iboga. For help, see substance use support and urgent help.

Conservation and sustainability

Sources describe concern about sustainability: demand, deforestation and political and economic conditions have led to questions about whether current harvesting is sustainable. [5] There are no official data on harvesting rates or trade. [4] The Chacruna article also reports that Gabon declared iboga a national treasure in 2000 and that, as of 2019, exporting it was restricted. [5] That is a secondary report, not Gabonese law, and we did not read the law. For wider context see Indigenous traditions, ethics and conservation.

Legal status

This is not legal advice, and laws change. Ibogaine is listed in Schedule I of US federal regulation (21 CFR 1308.11, US eCFR, read 2026-10-22). [10] A 2025 UK poison-service paper states ibogaine is not licensed in the United Kingdom. [9] Gabon and other countries: not verified from official sources. See psychedelic legal status by country.
