Due to the complexity of providing mental health services to people from various cultures, there is much debate among GMH advocates regarding the best way to proceed. While biomedical interventions offer some degree of help,...

To uncover whether psychedelic drugs attenuate fear memory responses would advance the development of better psychedelic-based treatments for posttraumatic stress disorder (PTSD). Ayahuasca (AYA), a psychedelic brew containing indolamine N, N-dimethyltryptamine (DMT) and β-carbolines, facilitates fear extinction and improves neural plasticity. Upon retrieval, fear memory undergoes labilization...
The effects of so-called "psychedelic" or "hallucinogenic" substances are known for their strong conditionality on context. While the so-called culturalist approach to the study of hallucinations has won the favor of anthropologists, the vectors by which the features of visual and auditory imagery are structured by social context have been so far little explored. Using ethnographic data...
Abstract Research on psychedelic‐assisted psychotherapy has shown that music affects therapeutic outcomes at a fundamental level. The development of such therapies calls for research on the use of music with consciousness‐altering substances, especially in contexts informed by their traditional use. Informed by ethnographic reports, our project answers this call, investigating the phenomenology...
Abstract Ayahuasca is a psychoactive and psychedelic decoct composed mainly of Banisteriopsis caapi and Psychotria viridis plant species. The beverage is rich in alkaloids and it is ritualistically used by several indigenous communities of South America as a natural medicine. There are also reports in the literature indicating the prophylaxis potential of Ayahuasca alkaloids against internal...
Abstract Background and aims The benefits of classic serotonergic psychedelics (e.g. psilocybin, LSD, DMT, ayahuasca) are becoming more widely known with the resurgence in research in the past decade. Furthermore, the benefits of mindfulness are well documented. However, no systematic reviews have examined linkage of mindfulness and psychedelics use. The aim of this systematic review is to...
Ayahuasca is an Amazonian drink, which contains β-carboline alkaloids and N,N-dimethyltryptamine. The aim of this study was to evaluate the healing potential of decoctions of a commercial mixture, four individual plants and four mixtures of two plants used in the ayahuasca preparation. Thus, the cytotoxic potential of the samples was evaluated and a wound-healing assay was performed with a NHDF...

Aims Compare, describe and analyze psychological effects and subjective experiences of ayahuasca ceremonies in two different groups: a psychospiritual holistic center, and a center specialized in substance use disorder's treatment. Methods A mixed...
This study sought to investigate the effects of different substances on nature relatedness (NR) in the general population. An online cross-sectional survey done in Brazil investigated use of ayahuasca/DMT, psilocybe mushrooms, LSD, MDMA/ecstasy, cocaine, cannabis, and alcohol. NR was assessed using the short-form version of the nature related scale (NR-6). One-way analysis of variance (ANOVA)...
Abstract This article addresses the sacredness of Ayahuasca from the perspective of the global shamanic vocation. If encounters with Ayahuasca are said to revitalize forms of sacredness in contemporary societies, this is perhaps clearest in cases where individuals understand themselves to be called to lead ceremonies. Recognizing the global scale of Ayahuasca shamanism, we compare facilitators...
<p>Disruptions to the sense of self are dotted across cultures and times in rituals involving hallucinogens, sensory deprivation, trance possession, and meditation. Much of the research on the self or “ego” suggests that the self is a complicated, multi-faceted entity and that there are many aspects that hold together our ego. Yet, current measurements on ego-dissolution focus on a narrow...
Recent studies have recognized the importance of non-pharmacological factors such as setting to induce or promote mystical experiences or challenging experiences among ayahuasca users. This study aimed to evaluate the association between the setting in which ayahuasca is consumed and the intensity of mystical and challenging experiences considering three ayahuasca using traditions (União do...
The objective of this study was to evaluate the behavioral response of ayahuasca in rats submitted to neuroinflammation through the intraperitoneal application of lipopolysaccharide (0.63 mg/kg/mL). Eighty animals, male, about 90 days old, were divided into control and LPS groups and later into prevention and treatment subgroups. The prevention subgroup was administered ayahuasca or saline...
ABSTRACT This research qualitatively investigated four treatments for addiction in Brazil that use ibogaine as the main tool in the process. Ibogaine is a substance derived from an African plant, Tabernanthe iboga, traditionally used in its region of origin and which leads to intense sensations during its acute effects and also different experiences of oneself and the surrounding world in the...
Psychedelics are increasingly being recognized for their potential to treat a wide range of brain disorders including depression, post-traumatic stress disorder (PTSD), and substance use disorder. Their broad therapeutic potential might result from an ability to rescue cortical atrophy common to many neuropsychiatric and neurodegenerative diseases by impacting neurotrophic factor gene...
Resumen El ritual chamánico de la ayahuasca ha sido adoptado, adaptado y reinventado en contextos urbanos y cosmopolitas de diferentes países del mundo, un proceso que ha estado fuertemente permeado por prácticas y creencias de tipo new age . Una de las versiones locales de este fenómeno se conoce en Colombia como “tomas de yajé”, donde participan citadinos no indígenas de clase media y alta en...
Traditional Amazonian medicine, and in particular the psychoactive substance ayahuasca, has generated significant research interest along with the recent revival of psychedelic medicine. Previously we published within-treatment quantitative results from a residential addiction treatment centre that predominately employs Peruvian traditional Amazonian medicine, and here we follow up that work...
Ayahuasca has spread from indigenous Amazonia to the industrialized world, in the form of ceremonies catering to Westerners, a corpus of academic studies and personal accounts and depictions of it in novels and films. Considering that its original users were zealous about revealing it to outsiders and their traditional cultures were being eroded by the mainstream’s society’s colonization, its...

Ayahuasca is becoming more popular in western countries for therapeutic use for depression, drug addiction, and emotional distress (Domínguez-Clavé et al., 2016). Previous research has explored the effects ayahuasca may have on cognition, neurological functioning, and psychopathology....
