ABSTRACT Ayahuasca is a beverage with psychoactive properties used in religious and ceremonial rituals by some religious groups. The main active components of ayahuasca are dimethyltryptamine and the harmala alkaloids with β-carboline structure acting as monoamine oxidase A inhibitors. This combination produces a pronounced activation of serotonergic pathways and presents potential interaction...

In the past decade, an increasing number of clinical trials are reporting evidence that psychedelics or serotonergic hallucinogens (such as lysergic acid diethylamide, psilocybin, and ayahuasca/dimethyltryptamine) could be effective in the treatment of mood, anxiety, and substance use disorders. The mechanisms responsible for these effects are not fully understood but seem to involve changes in...

A ayahuasca é um chá que se obtém através da mistura de plantas brasileiras. Já existem várias hipóteses que corroboram suas ações antidepressivas pela inibição da enzima monoamina oxidase (MAO) e de virada maníaca com o seu uso. Este artigo descreve o caso de um homem de 30 anos de idade com diagnóstico de transtorno bipolar tipo 1 (TB tipo 1) prévio, que apresentou, após o consumo do chá,...

Ayahuasca is a hallucinogenic beverage produced from the decoction of Banisteriopsis caapi (Bc) and Psychotria viridis (Pv), β-carboline- and N,N-dimethyltryptamine(DMT)-containing plants, respectively. Accumulating evidence suggests that ayahuasca may have therapeutic effects on ethanol abuse. It is not known, however, whether its effects are dependent on the presence of DMT or if...

Hallucinations possess two main components: (i) a sensory content; (ii) a sense that the sensory content is real. Influential models of schizophrenic hallucination claim that both the sensory content and the sense of reality can be explained in terms of metacognitive dysfunction. This chapter assesses whether such a claim holds for schizophrenic and drug-induced hallucinations; it further...

Ayahuasca, a psychoactive plant decoction, has spread from indigenous communities in South America to urban areas in the Americas, Europe, and Australia where it is used in neoshamanic rituals. This paper draws on ethnography of Australian ayahuasca ceremonies to examine the ways that individualism shapes the structure of ayahuasca rituals, the interpretation of visionary experiences, and...

Major depression is a highly prevalent mood disorder, affecting about 350 million people, and around 30% of the patients are resistant to currently available antidepressant medications. Recent evidence from a randomized controlled trial (RCT) supports the rapid antidepressant effects of the psychedelic ayahuasca in treatment-resistant depression. The aim of this study was to explore the effect...

Oferecendo-se mais como uma fala do que um artigo, este texto é um relato etnográfico sobre um movimento de recriação do xamanismo que tem animado o povo Yudjá nos últimos cinco anos e que foi deslanchado por seu encontro com a ayahuasca. A fim de desdobrar o meu próprio encontro com esse encontro, procuro criar uma vizinhança ou afinidade entre o movimento Yudjá, o conceito deleuze-guattariano...

\n A temporalidade compõe os atos da pessoa no mundo. A subjetividade assume papel importante, a partir dela é que o tempo adquire sentido e significado. Desta forma, a percepção subjetiva do tempo torna-se essencial para a percepção da realidade, delineando uma distinção entre o decurso temporal dos eventos vividos ao longo da vida, o que implica que o processamento da informação temporal é...

Ayahuasca ingestion modulates brain activity, neurotransmission, gene expression and epigenetic regulation. N,N-Dimethyltryptamine (DMT, one of the alkaloids in Ayahuasca) activates sigma 1 receptor (SIGMAR1) and others. SIGMAR1 is a multi-faceted stress-responsive receptor which promotes cell survival, neuroprotection, neuroplasticity, and neuroimmunomodulation. Simultaneously, monoamine...

The low efficacy of crack cocaine addiction treatment available in Brazil has led Brazilian users to find alternatives to reduce drug consumption or even to reach abstinence. One of them is the use of entheogenic substances, like ayahuasca, an infusion obtained from two native plant species from the Amazon. The present report aimed to understand how crack cocaine users recover from drug...

Background: The therapeutic effects of the Amazonian plant tea ayahuasca may relate to its ability to enhance mindfulness capacities. Ayahuasca induces a modified state of awareness through the combined action of its active principles: the psychedelic N,N- dimethyltryptamine (DMT) and a series of centrally acting β-carbolines, mainly harmine and tetrahydroharmine. To better understand the...

Rats were treated orally with ayahuasca (AYA) on gestation days (GD) 6-20 at doses corresponding to one-(1X) to eight-fold (8X) the average dose taken by a human adult in a religious ritual, and the pregnancy outcome evaluated on GD21. Rats treated with 4X and 8X doses died during the treatment period (44 and 52%), and those that survived showed kidney injury. Rats surviving the 8X dose showed...
