Óni · ayahuasca, the vine
Banisteriopsis caapi
The vine itself — not the brew. Cut, pounded and cooked for many hours with the leaf. In our materials óni is the plant; the ceremony is something you do with it.
The Shipibo word usually translated "medicine" covers far more than treatment. It names a whole category of relationship between people and plants.
Shipibo teaching The Shipibo name comes first, in bold. Where a name is still with the speakers recording this course, we mark it. We publish a name when it comes from someone who speaks the language.

Banisteriopsis caapi
The vine itself — not the brew. Cut, pounded and cooked for many hours with the leaf. In our materials óni is the plant; the ceremony is something you do with it.

Psychotria viridis
The leaf cooked together with the vine. Its Shipibo name is one of the things we have asked our speakers for — chakruna is Quechua, not Shipibo.

Nicotiana rustica
Far stronger than the tobacco in a cigarette, and used almost everywhere: blown over a patient, drunk, smoked, kept close. People who know only cigarettes are always surprised by how central it is.

Cyperus articulatus
A family of sedges, grown deliberately. Different varieties are kept for different purposes — healing, skill, protection, and for the hand that embroiders kené.

Mansoa alliacea
Smells of garlic; nothing to do with garlic. Dieted for clarity and for cleaning heaviness out of the body.

Calliandra angustifolia
A riverbank tree with pink filament flowers. Associated with the heart, and with opening a person rather than hardening them.

Brunfelsia grandiflora
Named for the cold it produces — the body shivers while the plant works. A serious diet, not a beginner's.

Couroupita guianensis
The bark is dieted for strength and protection. One of the plants people mean when they speak of a diet that defends you.

Maytenus macrocarpa
Bark, usually in aguardiente or as a decoction. Taken for the back, the joints, and for endurance.

Ficus insipida
A strangler fig that grows down into itself. Used for binding — for what has come apart, in the body and otherwise.

Jatropha gossypiifolia
Planted at the edge of a house. Used in cleansing baths and in protection.

Tabernaemontana undulata
Dieted for memory and for grief — the plant people name when something has to be carried differently.
What outsiders most often miss: in Shipibo practice, the plant is rarely the point by itself. The point is the trained relationship — formed through dieta, maintained through discipline, expressed through song — bewá. A brew without that relationship is, in the traditional view, just a brew.
How an onanya (healer)'s relationship with plants is actually built — and what the songs have to do with it — is the subject of the cosmology introduction and, in full depth, our forthcoming guide and advanced courses.
Beyond the plants every visitor hears about, Shipibo onanyabo — healers draw on a broad living pharmacy — teacher plants dieted over months, and everyday remedies for the body's troubles. A selection, by the names most used in the region:
Some of what has been written about this elsewhere: a 2021 observational study in Frontiers in Pharmacology (González et al.) followed participants in Shipibo ceremonial ayahuasca use and reported improvements in well-being measures. It is one study, in one context. The practice does not depend on it.
