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...
Background: Ayahuasca, a traditional Amazonian decoction with psychoactive properties, is made from bark of the Banisteriopsis caapi vine (containing beta-carboline alkaloids) and leaves of the Psychotria viridis bush (supplying the hallucinogen N,N-dimethyltryptamine, DMT). Originally used by indigenous shamans for the purposes of spirit communication, magical experiences, healing, and...
Abstract Background Ayahuasca is a botanical hallucinogenic preparation traditionally used by indigenous populations of Northwestern Amazonian countries for ritual and therapeutic purposes. It is rich in β-carboline alkaloids and N,N-dimethyltryptamine (DMT). Preclinical, observational, and experimental studies suggest that ayahuasca and its alkaloids have anxiolytic and antidepressive effects....

Plantas alucinógenas são bastante utilizadas em rituais e cultos religiosos. O chá de Ayahuasca e o vinho da Jurema preta, bebidas alucinógenas, apresentam o alcalóide dimetiltriptamina (DMT), responsável pelo efeito alucinógeno devido a interação com receptores serotoninérgicos no sistema nervoso central (SNC). O objetivo da pesquisa foi esclarecer os mecanismos de ação e os efeitos da DMT...
Serotonergic hallucinogens, such as lysergic acid diethylamide (LSD), psilocybin, and N,N-dimethyltryptamine (DMT), are famous for their capacity to temporally and profoundly alter an individual's visual experiences. These visual alterations show consistent attributes despite large inter- and intra-individual variances. Many reports document a common perception of colors as more saturated, with...
Hallucinogens evoke sensory, perceptual, affective, and cognitive effects that may be useful to understand the neurobiological basis of mood and psychotic disorders. The present chapter reviews preclinical research carried out in recent years in order to better understand the action of psychotomimetic agents such as the noncompetitive NMDA receptor (NMDA-R) antagonists and serotonergic...
New World indigenous peoples are noted for their sophisticated use of psychedelic plants in shamanic and ethnomedical practices. The use of psychedelic plant preparations among New World tribes is far more prevalent than in the Old World. Yet, although these preparations are botanically diverse, almost all are chemically similar in that their active principles are tryptamine derivatives, either...
La ayahuasca es una bebida alucinógena, producto de la decocción de las plantas Banisteriopsis caapi y Psychotria viridis y que cuenta con N,N-dimetiltriptamina y β-carbolinas, como sus compuestos principales. Aunque produce alteraciones somáticas, cognitivas y subjetivas agudas, a menudo intensas, casi no se han reportado efectos adversos luego de un cuadro de intoxicación con este agente. En...
Abstract Ayahuasca is a natural psychedelic brew, which contains dimethyltryptamine (DMT). Its potential as a psychiatric medicine has recently been demonstrated and its non-medical use around the world appears to be growing. We aimed to investigate well-being and problematic alcohol use in ayahuasca users, and ayahuasca’s subjective effects. An online, self-selecting, global survey examining...
BACKGROUND: Novel psychoactive substances (NPS) can be classified based on their safety for use into low-risk and high-risk. High-risk NPS can be either lethal or poisonous. Fatalities can be either pharmacological or behavioural-induced, including suicide and homicide.MATERIALS & METHODS: Observational analysis, including retrospective, were implemented across; Google Trends, PubMed/MedLine...
