Ayahuasca Characterization, Metabolism in Humans, and Relevance to Endogenous DMT - Ethan McIlhenny

Ayahuasca brews are characterized through a detailed analytical procedure designed to quantify eleven compounds, identifying tetrahydroharmine and harmine as major components alongside DMT. This chemical analysis establishes standardized methods for future clinical research, demonstrating that while the concentrations of key alkaloids vary by source, their specific ratios remain consistent. Metabolic studies of humans reveal that DMT undergoes rapid conversion into metabolites like DMT-N-oxide, with minimal unchanged DMT recoverable in urine. These clinical findings suggest that monitoring metabolic markers provides a more reliable method than direct detection for assessing DMT presence in the body. Furthermore, immunohistochemical research in primates localizes the enzyme INMT to specific tissues like the lung, heart, and retina, supporting ongoing investigations into the endogenous production of small amounts of DMT within the human system.
