Amber Antonelli and Anthony Esposito run the Awaken Your Soul iboga retreat center in Costa Rica. Iboga is the name of a plant native to Gabon and neighboring West African countries that acts as a psychedelic, or as Amber and Anthony put it, a "teacher plant." Iboga, along with its better-known (in the US) cousins, Ayahuasca and psilocybin-containing mushrooms, appears to act pharmacologically by down-regulating parts of the human brain responsible for the moment-by-moment construction of the ego.
