It is studied for potential antidepressant and neuroprotective effects. Also investigated for anticancer activity due to its ability to interfere with cell division and induce apoptosis in tumor cells. Found in traditional entheogenic brews like ayahuasca, where it enables the oral activity of DMT by inhibiting its breakdown in the gut.
