Ayahuasca is a botanical hallucinogenic preparation traditionally consumed by Northwestern Amazonian indigenous groups. Scientific evidence suggests good tolerability after acute administration of ayahuasca and also after years or even decades of its ritual consumption. Nevertheless, some scientific and media reports associate ayahuasca or some of its alkaloids with severe intoxications. The...
Ayahuasca needs little introduction. The proving took me to Brazil and I took the journey with shamans and I had a beautiful rendezvous with myself. Thereafter I have used it also as a homeopathic remedy in individuals who know their nature but could not transform (stuck) and especially in drug addicts (cocaine, alcohol, allopathic drugs).
The past decade has witnessed a surge of popular interest in the mestizo tradition of ayahuasca, variously referred to as curanderismo, vegetalismo, and/or ‘shamanism’. This interest in Ayahuasca, a psychotropic plant brew, is evidenced by the thriving industry of ayahuasca tourism that exists in Peru. Such ayahuasca ‘tours’ are predominantly attended by European, and North American...
This chapter expands the analysis of the social and cosmic dimensions of a process of ‘re-ritualization’ in urbanindustrial societies, inspired by the knowledge of ‘traditional populations. It focuses on primarily on providing a textured ethnography of role of religion and culture in the negotiation of alterity. The chapter epistemological thrust is to deconstruct the need for a circumscribed...

AIM: To evaluate changes in neurotransmission induced by a psychoactive beverage ayahuasca in the hippocampus and amygdala of naive rats. METHODS: The level of monoamines, their main metabolites and amino acid neurotransmitters concentrations were quantified using high performance liquid chromatography (HPLC). Four groups of rats were employed: saline-treated and rats receiving 250, 500 and 800...
Despite being relatively well studied from a botanical, chemical, and (acute) pharmacological perspective, little is known about the possible toxic effects of ayahuasca (an hallucinogenic brew used for magico-ritual purposes) in pregnant women and in their children, and the potential toxicity of long-term ayahuasca consumption. It is the main objective of the present text to do an overview of...
Ayahuasca is an Amazonian psychoactive plant beverage containing the serotonergic 5-HT(2A) agonist N,N-dimethyltryptamine (DMT) and monoamine oxidase-inhibiting alkaloids (harmine, harmaline and tetrahydroharmine) that render it orally active. Ayahuasca ingestion is a central feature in several Brazilian syncretic churches that have expanded their activities to urban Brazil, Europe and North...
Studying the effect of psychedelic substances on expression of creativity is a challenging problem. Our primary objective was to study the psychometric measures of creativity after a series of ayahuasca ceremonies at a time when the acute effects have subsided. The secondary objective was to investigate how entoptic phenomena emerge during expression of creativity. Forty individuals who were...
Eighty-one subjects who used ayahuasca at least once in North America answered a lengthy set of open-ended questions and completed the 81-item After the Spiritual Experience Questionnaire. An additional 50 ayahuasca users were interviewed in person. The data for this study represent ayahuasca experience based on more than 2,267 ceremonies. A comparison group of 46 people attending a Catholic...
