Yajé
Yajé is a psychoactive brew traditionally prepared by indigenous peoples of the Amazon basin. It is most commonly known in the West as ayahuasca, though yajé is the preferred term in Colombia and some other regions. The preparation involves the simmering of two specific plants: the leaves of a DMT-containing plant, typically Psychotria viridis (chacruna), and the bark of a vine, Banisteriopsis caapi (yagé or ayahuasca vine). The Banisteriopsis caapi vine contains harmala alkaloids, which act as monoamine oxidase inhibitors (MAOIs). These MAOIs are crucial because they prevent the breakdown of DMT in the digestive system, allowing it to become orally active and produce its characteristic visionary and introspective effects.
The consumption of yajé is deeply embedded in the spiritual and healing traditions of various Amazonian cultures.
