Estacion Kapitari - Traditional Ayahuasca retreat Peru, Authentic shamanic Ayahuasca retreat. Since 1981 we celebrate Ayahuasca ceremonies at Kapitari Center near Iquitos. The peruvian shamans mix the Ayahuasca vine with the dmt (dimethyltryptanine) containing Plant Chacruna and prepare a brew that is one of the strongest halluzinogens known to mankind.
