What iboga root bark is

Tabernanthe iboga is a shrub of the Apocynaceae family that grows in the understory of the rainforest in Gabon, Cameroon, Congo and neighboring countries. It reaches one to two meters, carries small yellow-white flowers and orange fruits, and lives for decades. The part used as medicine is not the leaf, the fruit or the wood: it is the bark of the root, and more precisely its second layer, scraped from the roots of mature plants.

The root bark contains a family of indole alkaloids. Ibogaine is the best known and the most abundant, but the bark also holds ibogamine, ibogaline, tabernanthine, coronaridine, voacangine and around a dozen others. Their proportions vary. Whole bark preserves the plant’s mixture; ibogaine hydrochloride is an isolated alkaloid. More compounds do not automatically mean more clinical benefits. Explore the alkaloid family, evidence and research analogues.

Our sourcing minimum

01 / Cultivation

A living plant. Years of care.

Iboga is a perennial shrub with elongated leaves and orange fruit. For Bwiti Life’s medicine, we specify at least seven years of growth before root harvesting.

Time is part of the source. Seven years is our stated sourcing minimum, not a measurement of alkaloid content.

02 / Below the surface

Harvest with care. Keep the plant alive.

In our Missoko Bwiti harvesting practice, songs and dances accompany meticulous collection. Only a small portion of roots is taken from a mature plant, which remains alive.

Preserve the living plant. At least seven years of growth precede this careful, limited harvest.

03 / A closer look

Bark around a woody core

This schematic section separates the root bark from the wood within it. The prepared bark contains a mixture of alkaloids, including ibogaine.

Whole bark, variable composition. The illustration is not to scale and does not show measured tissue or alkaloid proportions.

04 / Our sourcing

A relationship with the people who grow it

Our root bark is locally sourced from villages in Gabon that cultivate iboga, with fair agreements and resource sharing. Our practitioners prepare it within the Missoko Bwiti tradition.

How it is harvested

For the medicine we use, the plant grows for at least seven years before harvesting. In the Missoko Bwiti harvesting practice we follow, roots are collected meticulously within a ritual of songs and dances. Only a small portion of a plant’s roots is taken, leaving the plant alive. It is not uprooted or killed. The collected root bark is then prepared by the practitioners. Growing time alone does not establish alkaloid content or batch quality.

Gabon treats iboga as a national heritage and restricts the export of wild-harvested plant. Demand from abroad has put pressure on wild populations, which is why sourcing matters. Bwiti Life sources root bark from villages in Gabon that grow the plant, with fair agreements and resource sharing. Our practitioners prepare it within the Missoko Bwiti tradition.

How Bwiti practitioners prepare it

In the Missoko Bwiti tradition the bark is prepared by the nganga, the practitioner, with prayers and protections that are part of the medicine as much as the chemistry. The dried bark is shaved or ground into a coarse powder. In ceremony it is given in successive small doses through the night, on the tongue or with water, so that the practitioner can watch how each person responds before giving more.

The taste is intensely bitter and nausea is common. The pacing, the music and the presence of the practitioner are what make a twelve-hour night with this plant possible. Nobody in the tradition takes iboga alone.

Bark, powder, extract, ibogaine: the four forms

  • Whole root bark. Shavings of the dried second layer of the root. Full alkaloid spectrum, variable potency, used in ceremony. This is what we use.
  • Root bark powder. The same bark, ground. Easier to dose by weight, same spectrum, same variability.
  • Total alkaloid extract (TA). A concentrated mixture whose composition depends on the extraction process. It does not necessarily preserve the bark’s original ratios. Used by some ceremonial and clinical providers.
  • Ibogaine hydrochloride (HCl). The isolated alkaloid prepared as a hydrochloride salt. A verified preparation permits measurement of its ibogaine content; this does not remove its cardiac risks.

IbogaineOther alkaloidsPlant material

01 / Whole root bark

The plant’s mixture remains

Dried bark retains alkaloids alongside plant material. Its composition and potency vary. Whole root bark is the preparation we use within the Bwiti Life ceremonial process.

What we use. Whole bark, prepared by the practitioner and administered under medical supervision.

02 / Ground root bark

A change in texture

Grinding turns bark into powder. It does not isolate ibogaine or standardize the amount of each alkaloid.

The same source material. A finer texture is not evidence of a different therapeutic effect.

03 / Total alkaloid extract

A concentrated mixture

Extraction separates a mixture of alkaloids from much of the plant material. The compounds retained and their proportions depend on the process.

Ask what is in it. “Total alkaloid” is not a guarantee of original ratios, purity or potency.

04 / Purified ibogaine

One alkaloid, multiple actions

Ibogaine HCl is the isolated alkaloid in a salt form. It can be obtained from iboga or manufactured from voacangine sourced from Voacanga africana.

Source and composition are separate. Explore the Voacanga source route.
Illustrative forms and composition categories, not quantities, purity grades or rankings of benefit. Purified ibogaine can also have psychological effects. Read the evidence and full comparison.

All four can carry cardiac and interaction risks. Their relative safety cannot be inferred from the number of alkaloids alone. Screening and medical monitoring remain necessary. Read Iboga vs ibogaine for the full comparison.

Ibogaine can also come from Voacanga africana

Voacanga africana is a different African plant. Its alkaloid voacangine can be isolated and chemically converted into ibogaine, a route known as semisynthesis. A 2021 research paper describes this source route. Read the original research.

Plant sourceVoacanga africana
Starting alkaloidVoacangine
After conversionIbogaine

The resulting compound is ibogaine, not whole iboga root bark and not a different analogue merely because of its source. Raw Voacanga material is not interchangeable with iboga. The source plant alone does not establish the final product’s purity or safety, and we do not infer any clinic’s supplier from the words “ibogaine HCl.” Bwiti Life uses whole Tabernanthe iboga root bark from the Gabonese villages described above.

What it does to the body and the mind

Ibogaine and its main metabolite, noribogaine, act on several systems at once: NMDA glutamate receptors, kappa opioid receptors, the serotonin transporter, nicotinic receptors, and they raise the production of growth factors such as GDNF that support neuroplasticity. Noribogaine stays in the body for days, which is why the effects on craving and mood outlast the night itself.

Felt from the inside: an onset over one to two hours, then a long, lucid, introspective state in which memories and images pass at speed while the body is heavy and still. The experience lasts twelve hours or more, followed by a day of deep fatigue and, for many, unusually clear days after. Read How iboga works for the science and the references.

Safety

The root bark is not a supplement and not something to try at home. The cardiac effects are real: ibogaine lengthens the QT interval and slows the heart, which can lead to dangerous arrhythmias even in someone who appears healthy. Screening and monitoring do not eliminate that risk. Every guest at Bwiti Life goes through an ECG review and a blood panel before travel, and every ceremony runs with IV access, cardiac telemetry and a physician in the room. Our full protocol is on the Safety page.

Bark and powder sold online, when they are even genuine, come without any of this. We would rather you never take iboga than take it that way.

Legality

Iboga and ibogaine are not scheduled in Mexico, where our retreats take place, and are legal in Gabon. They are Schedule I in the United States and controlled in several European countries. Nothing about the medicine should cross a border. Read Is iboga legal? for the country-by-country picture.

Questions people ask

Can I buy iboga root bark online?

You can find it offered, in countries where it is legal and in many where it is not. Genuine or not, it comes without screening, without dosing experience and without a medical team. The cardiac risk does not care where the bark came from. Do not self-dose.

How much root bark is a ceremonial dose?

It depends on the potency of the bark, the person, and the practitioner. In ceremony the dose is built up in steps through the night, not given at once, which is the point: the practitioner adjusts to what they see. We do not publish gram amounts because they are meaningless without the bark in hand and the person in front of you.

Does the bark contain more than ibogaine?

Yes. Ibogaine is the most abundant alkaloid, but the bark holds a dozen others, including ibogamine, tabernanthine and coronaridine, whose contributions are only beginning to be studied. A broader mixture does not establish broader clinical benefits. Our choice combines whole bark with a specific ancestral process; read why.

Is iboga endangered?

Wild populations in Gabon are under pressure from demand. Gabon restricts export, and serious providers source from cultivated plants. Ask any provider where their bark comes from; if they cannot answer, that is your answer.
