Effects of ayahuasca in preclinical studies with animals: a systematic review.
Synthesis in Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This systematic review investigates the effects of the ayahuasca beverage (Aya) in various animal models. Using the PRISMA protocol and adhering to the Cochrane Handbook for Systematic Reviews, a comprehensive selection of 2,359 documents was identified from the Web of Science, Medline, and Scopus databases between 2012 and 2022. Following the inclusion and exclusion criteria, 14 articles were included in the final analysis. The analysis revealed a diversity in the selection of animal models that included different developmental stages and various forms of Aya intoxication, including acute and chronic doses, and varying concentrations of the active principles. The studies revealed that Aya causes significant alterations in the motor and cognitive behavior of animals, especially associated with the serotonergic system, which seems to contribute to the negative symptoms also observed in schizophrenia and depression. Despite the evidence found, this review highlights the scarcity of more robust pre-clinical studies with methodological standardization to make more conclusive comparisons, especially given the need to identify potential toxic and neurochemical effects of Aya on organisms for a safer assessment of its therapeutic use.
