Ayahoasca: an experimental psychosis that mirrors the transmethylation hypothesis of schizophrenia.

Journal of ethnopharmacology  – April 01, 1999

Summary

Certain hallucinogenic compounds found in healthy individuals after consuming Ayahuasca are identical to those seen in acute psychotic patients. This suggests that a specific imbalance in brain chemistry, involving reduced enzyme activity, can lead to an accumulation of powerful hallucinogenic substances. Researchers examined the effects of Ayahuasca, a traditional Amazonian beverage with natural enzyme inhibitors and DMT, on volunteers. Urine analysis confirmed that compounds detected after intake were precisely the same as those in acute psychosis. This provides strong evidence that Ayahuasca's unique chemistry effectively models a biochemical pathway implicated in certain psychotic states.

Behavioral and pharmacokinetic interactions between monoamine oxidase inhibitors and the hallucinogen 5-methoxy-N,N-dimethyltryptamine.

Pharmacology, biochemistry, and behavior  – April 01, 2016

Summary

The way our body processes psychedelics can profoundly alter their impact. New research explored how monoamine oxidase inhibitors (MAOIs), similar to those in ayahuasca, modify the effects of the tryptamine 5-methoxy-N,N-dimethyltryptamine. Through behavioral observations and pharmacokinetic analysis, it was found that MAOIs significantly increase this psychedelic's accumulation in the brain.

Why psychedelic-assisted therapy studies in eating disorders risk missing the mark on outcomes: a phenomenological psychopathology perspective.

J Eat Disord  – September 02, 2025

Summary

Understanding eating disorders solely through observable symptoms may overlook their deepest roots. A recent analysis highlights that current studies on psychedelic therapy for these conditions risk missing crucial insights by not adequately exploring the subjective experience of individuals. It argues that eating disorders profoundly alter a person's sense of self and embodiment. Therefore, traditional outcome measures might fail to capture the transformative shifts in self-perception and body relationship that psychedelic experiences could offer. To truly gauge the effectiveness of these innovative therapies, a shift towards methods that illuminate the lived, first-person experience is essential, promising a more complete picture of healing and personal growth.
