Iboga in Gabon

Iboga is not a crop. It is a forest shrub that takes years to reach a size worth harvesting, and the part that is used is the root bark, which means harvesting it is frequently the end of that plant.

A plant, a country, a religion

The species grows across Central Africa, from Cameroon and the Congos to Angola, and Gabon is where its range and its ritual use overlap most closely. Its place in Bwiti there is current practice rather than historical background.

The plant is often described abroad as Gabon’s “national heritage plant”. A Council of Ministers declaration to that effect is reported in the Gabonese press as dating from July 2000, but we have not located a primary instrument behind it, so we do not repeat it as law.

What does exist, in the official gazette, is more recent and more specific.

Two instruments the English-language debate has not caught up with

An arrêté of 4 February 2019, published in the Journal Officiel, suspended the export of iboga “à titre conservatoire”, in whole or in part, raw or derived. Exceptional authorisations remain possible after technical advice. That suspension has stood for over seven years, which means the phrase “unregulated export”, common in writing about iboga, has been wrong for most of the period it describes.

Then on 22 May 2026, décret n° 0239/PR/MJSRCAVA entered the gazette, regulating access, use, exploitation, research, processing and commercialisation of iboga. It is a framework for the whole chain rather than a prohibition, and it is three months older than this page.

Both are Gabonese texts about a Gabonese plant, and both are largely absent from the English-language conversation, which continues to describe a legal vacuum the source country has been filling since 2019.

Why the botany matters to the ethics

Three facts about the plant set the terms of everything that follows.

It grows slowly, in forest understorey, and does not lend itself to rapid cultivation at the scale export demand implies.

The useful material is root bark, so harvesting is destructive rather than a pruning.

And its alkaloid content is not uniform, which is why material sold abroad has no reliable strength. That last point is where this section meets the safety pages: the variability that makes buying iboga online dangerous is a property of the plant, not only of the sellers.

Who earns

The people who hold the knowledge that brought iboga to Western attention are not, for the most part, the people earning from its export.

That is the situation the Nagoya Protocol on Access and Benefit-sharing was written to address, through obligations on access to genetic resources and to the traditional knowledge associated with them. What the protocol does, what it does not reach, and where Gabon stands under it are set out on biopiracy and the Nagoya Protocol.

What we could not establish

One negative holds and two do not, and the distinction is worth making precisely.

No wild population figure exists. Tabernanthe iboga is assessed by the IUCN as Least Concern, on the basis of a wide distribution and no identified major threat. Its population-trend field reads “Stable” with nothing behind it, its count of mature individuals is blank, and Gabon has yet to carry out a nationwide survey. The species has a conservation category and nobody has counted it.

Harvest and revenue figures do exist, at permit level rather than as national statistics. Legal exports resumed in small authorised batches from 2023, in the order of a first kilogram for analysis and then a hundred kilograms authorised in twenty-kilogram shipments, under a pilot agreement between the forestry ministry and a village-level association. Payments attached to those shipments have been reported as figures, including a lump sum and a share of downstream clinical revenue, with an obligation on the communities to reinvest part of it in collective projects.

What is genuinely missing is aggregate trade data. With export suspended since 2019 there is no customs series to publish, so what exists is permit-level and seizure-level rather than a national account of what leaves the country.
