Research on endogenous DMT and beta‑carbolines mentions ayahuasca and historical shamanic use

Research on endogenous DMT and beta‑carbolines mentions ayahuasca and historical shamanic use The passage discusses biochemical findings on DMT and MAO‑inhibiting beta‑carbolines, citing historical ethnobotany and academic papers. It contains no concrete leads involving high‑level officials, financial transactions, or misconduct, and offers no actionable investigative angles beyond general scientific interest. Key insights: Human brain can synthesize beta‑carbolines that protect DMT from degradation.; Endogenous DMT may circulate long enough to cross the blood‑brain barrier after oral ingestion.; The ayahuasca mixture (Psychotria viridis + Banisteriopsis caapi) mirrors endogenous chemistry.
