Dr. Potter shares his experience learning about psychotropic plants from indigenous shamans in Brazil and Mexico. We discuss the cross-cultural transfer of psychoactive plants (e.g. psychedelic mushrooms and ayahuasca) and how we can learn from indigenous tribes and use plant-based medicines to treat mental illness, like addiction and OCD. Dr. Potter also reveals his latest research at Leef Labs, where he is creating major and minor cannabinoid formulations for insomnia and pain relief.
