This research is based on the interest in knowing and understanding the role that an entogen like ayahuasca can play in human development, within a context such as ritual. For this we make a participating observation and through visual anthropology we have gathered information about the ritual of ayahuasca (natem) in the Shuar community of Shaime. We have also observed the social changes that are taking place in the community because of the effects of globalization. One of the conclusions is that ayahuasca consumption survives despite the process of globalization and acculturation processes, however strong they have been. The most important entheogen substance is natem (nathema or natema) which in Quechua is ayahuasca. It is a potion made mainly with a vine, which according to Richard Spruce’s scientific name, is the Banisteria Caapi. This drink is used for medical, religious or magical purposes. Natem is prepared in several ways depending on whether it will be used to cure the sick, for holiday rituals or whether it will be taken by healers to perform their work (Naranjo, 1969). Among adults shuar the consumption of ayahuasca acts as a mechanism of social default. They use ayahuasca to solve their problems, to reaffirm their worldview and to contact their mythical world. They take it to talk about their Arutam, to give them power and to establish social rules and procedures, to condition themselves to strengthen ideas concerning solutions and to channel mental processes in a sense that we might call open to interpretations. This gives them a deep sense of certainty and security that characterizes the personality and forms of behavior of the Shuar (Mashinkiash, 1988).
