União do Vegetal and hoasca research

Record summary

The União do Vegetal is a Brazilian religion founded by José Gabriel da Costa that uses hoasca, an ayahuasca preparation, in structured ceremonies. Researchers have examined members’ psychological profiles, mental health, cognition, and long-term ritual participation, while members describe spiritual learning and contact with sacred realities. This lead is valuable for separating acute pharmacology, expectancy, religious interpretation, and longitudinal wellbeing. Findings depend on sample selection, self-report, cultural setting, and the distinction between clinical outcomes and metaphysical claims.
