The vine, the lab, and the elders

From Latin America and the Caribbean·A current case, last reviewed September 2026

As clinical interest in ayahuasca-derived compounds accelerates, Amazonian communities that developed and ritually govern the brew's use are often absent from the patents, trials and profits built on it. The pharmacology travels easily; the ceremonial knowledge and its custodians are treated as background.

The concepts this raises

Each of these gives a class a different way into the same case.

PowerKnowledge and Society
The capacity to shape what counts as knowledge, who is heard, and what gets funded, published or taught. Power is not only censorship; setting an agenda, controlling a platform or being granted authority all change the knowledge that a community ends up with.
ValuesKnowledge and Society
What a knower or a community takes to be worth pursuing, protecting or preferring. Values operate inside knowledge production and not just around it: they select the problems, set the acceptable risk of error, and decide which trade-offs count as costs.

Where it sits in the knowledge framework

Ethics
The ethical questions internal to the knowledge itself: what may be investigated and how, what obligations the knowledge places on those who hold it, and the ethical constraints the discipline imposes on its own practitioners.

Areas of knowledge

Themes

The same ideas, somewhere else

Cases that raise a concept this one raises, but in a different area of knowledge or a different part of the world. That contrast is the point: it is what shows a student the concept travels.
