Ayahuasca is a psychoactive Amazonian plant brew. It is usually made from the Banisteriopsis caapi vine (Spruce ex Griseb. Morton, Malpighiaceae), which contains three primary harmala alkaloids, along with the leaves of Psychotria viridis (Ruiz et Pavon, Rubiaceae) in which the potent psychedelic dimethyltryptamine (DMT) is found. DMT-harmaloid concoctions have gained popularity in recent...

Harmful usage of tobacco is a global public health problem associated with adverse health effects and addiction. Yet, in the Peruvian Amazon, the native region of Nicotiana rustica L., this plant is used in remarkably different manners: it is considered a potent medicinal plant, applied in liquid form for oral ingestion to treat mental health problems, a common and ancient healing practice in...

To make oral DMT bioavailable, ayahuasca additionally contains reversible monoamine oxidase A (MAO-A) inhibitors, namely β-carboline alkaloids such as harmine. However, there is lacking biochemical...

Abstract This article describes the associations and controversies between indigenous and western uses of ayahuasca between 1850 and 1950 in relation to the “psychedelic renaissance.” This movement has gained scientific attention since 2000, but hearkens back to the 1960s and 1970s, when anti-drug policy halted research on the “therapeutic potential” of psychoactive substances. Pioneering...

Ayahuasca often yields transformative experiences that merge such familiar categories as the sacred and the secular, transcendence and immanence, subject and object, and the human and the nonhuman. However, such experiences are interpreted differently by Western and indigenous discourses. Using the work of French philosopher Bruno Latour, André van der Braak asks fundamental ontological...
