RESUMO

Moving towards a systems psychiatry paradigm embraces the inherent complex interactions across all levels from micro to macro and necessitates an integrated approach to treatment. Cortical 5-HT2A receptors are key primary targets for the effects of serotonergic psychedelics. However, the therapeutic mechanisms underlying psychedelic therapy are complex and traverse molecular, cellular, and network levels, under the influence of biofeedback signals from the periphery and the environment. At the interface between the individual and the environment, the gut microbiome, via the gut-brain axis, plays an important role in the unconscious parallel processing systems regulating host neurophysiology. While psychedelic and microbial signalling systems operate over different timescales, the microbiota-gut-brain (MGB) axis, as a convergence hub between multiple biofeedback systems may play a role in the preparatory phase, the acute administration phase, and the integration phase of psychedelic therapy. In keeping with an interconnected systems-based approach, this review will discuss the gut microbiome and mycobiome and pathways of the MGB axis, and then explore the potential interaction between psychedelic therapy and the MGB axis and how this might influence mechanism of action and treatment response. Finally, we will discuss the possible implications for a precision medicine-based psychedelic therapy paradigm. (AU)

RESUMO

Introducción. Numerosas sociedades indígenas de Sudamérica esnifan, desde tiempos inmemoriales, diversos rapés de semillas con propiedades alucinógenas y fines magicorreligiosos.Objetivos. Describir las evidencias arqueológicas, históricas y etnográficas del uso ritual de las semillas de la vilca o yopo (Anadenanthera sp).Desarrollo. Las semillas de Anadenanthera se emplean en América del Sur desde hace más de 3.000 años. Evidencias arqueológicas muestran la presencia de la vilca en restos funerarios del año 1000 a.C. en el norte de Chile y Argentina; piezas cerámicas y esnifadores de las mismas fechas se han encontrado en yacimientos arqueológicos del desierto de San Pedro de Atacama, Chile, y en Tiwanaku, en el altiplano boliviano. En la actualidad diversos grupos indígenas de la cuenca del Orinoco, Amazonia brasileña y colombiana, consumen las semillas de Anadenanthera sp. El efecto alucinógeno se debe a la presencia de diversos derivados de la dimetil-triptamina. El rapé está formado por el polvo tostado de las semillas molidas de Anadenanthera, junto con extractos de ceniza alcalina obtenida de cortezas de árboles o de cal extraída de conchas de moluscos.Conclusiones. Los hallazgos arqueológicos y etnográficos indican que la vilca fue y sigue siendo empleada por los chamanes como semilla sagrada, por su efecto alucinógeno, en toda Sudamérica


Introduction. Several South-American native societies snuff psychoactive seeds in magic-religious rituals since ancient times.Objectives. To describe archeological, historical and ethnographical evidences regarding the ritual use of vilca or yopo (Anadenanthera sp).Development. Anadenanthera seeds were used in South America 3,000 years ago. Archeological studies found vilca seeds in funerary tombs from 1,000 BC in the north of Chile and Argentina; ceramics and snuff tubes were found in San Pedro de Atacama archeological sites from the same data, and in Tiwanaku ceremonial center in Bolivian Altiplano. Today, Anadenanthera sp is used by several native groups in Orinoco basin, where is known as yopo, and in the Brazilian and Colombian Amazon. Hallucinogenic effect is due to the presence of methyl-tryptamine derivatives. Most snuff is prepared from the roasted and powdered seeds, vegetable ash and/or lime obtained from shells.Conclusions. Archeological and ethnographical data suggest that vilca was used and is still used by native shamans as a sacred seed in South America, due to its hallucinogenic effects
