Iboga vs ayahuasca

Two plants, two continents, two traditions

Iboga is the root bark of Tabernanthe iboga, used for generations by the Bwiti of Gabon in initiations and healing ceremonies, around a fire, with Missoko Bwiti Music and sacred Songs, under the guidance of a practitioner. Ayahuasca is a brew of two Amazonian plants, the Banisteriopsis caapi vine and, most often, the leaves of Psychotria viridis, used by indigenous peoples of Peru, Brazil, Colombia and Ecuador and by syncretic churches such as Santo Daime.

The traditions differ in structure as much as in geography. A Bwiti ceremony is usually one long night with a single medicine given in steps; an ayahuasca retreat is typically several ceremonies over consecutive nights, each of a few hours.

The chemistry

Iboga acts through ibogaine and the other alkaloids of the bark, and through noribogaine, the long-lived metabolite that keeps working for days. Its targets include NMDA and kappa opioid receptors, the serotonin transporter, and the growth factors that drive neuroplasticity.

Ayahuasca works through DMT, a short-acting tryptamine that the body would normally break down in minutes, made orally active by the harmala alkaloids of the vine, which inhibit the enzyme monoamine oxidase. That MAO inhibition is what makes ayahuasca interact dangerously with SSRIs and some foods; iboga has its own interaction list, centered on the heart.

What the experience is like

• Iboga: twelve hours or more. Onset over one to two hours, then a long, lucid, introspective state: memories and images pass at speed, often as a life review, while the body is heavy and still. Little visual overload, no sense of leaving oneself. Followed by a day of deep fatigue and clear days after.
• Ayahuasca: four to six hours. Onset in thirty to sixty minutes, strong visual and emotional content, a sense of presence or of other beings for many, purging (vomiting, sometimes diarrhea) that the tradition treats as part of the cleaning. Recovery by the next morning, repeated the next night.

• Iboga

  One night, given in steps. Noribogaine keeps working for weeks (outer ring).

• Ayahuasca

  Repeated on consecutive nights.

Guests who have done both often describe ayahuasca as being shown something, and iboga as being made to look at something.

Safety and screening

Ayahuasca's main risks are interactions: SSRIs, MAOIs, lithium and some other medications can cause serotonin syndrome or hypertensive crises, which is why retreats ask for a diet and a medication washout. Cardiac risk exists but is lower.

Iboga's main risk is the heart: QT prolongation and slowed heart rate, dangerous with pre-existing conditions, low electrolytes or certain medications. This is why a serious iboga provider runs an ECG and bloodwork before travel and keeps a physician, IV access and telemetry in the room. Most ayahuasca retreats do not have a physician on site; most iboga retreats should, and ours does. Our protocol is on the Safety page.

What each is used for

Ayahuasca is most often sought for emotional and spiritual exploration, grief, depression and a sense of connection. Iboga is sought for the same, and in addition for something ayahuasca does not do: interrupting physical dependence, on opioids in particular, and resetting craving. It is also the medicine people choose when they want one deep night rather than a week of ceremonies, and a review of their own life rather than visions.

Legal status

Ayahuasca is legal in Peru, Brazil and Colombia, tolerated in some countries, and illegal in others because of its DMT content; religious exemptions exist in the United States for some churches. Iboga and ibogaine are not scheduled in Mexico or Gabon, Schedule I in the United States, and controlled in several European countries. Details in Is iboga legal?

How to choose

If you are looking for a visionary, communal, multi-night experience with a lighter medical load, ayahuasca may be the better fit. If you want a single, deep, lucid night with your own history, if dependence or a long-standing pattern is what you are trying to break, or if you want the medical safeguards of a clinical frame inside a tradition, iboga is the one. Many people do both in their life, years apart, for different questions. Neither is a shortcut.
