In order to enhance the life hope of the American Indian people disseminated in the Equatorian jungle, a group of doctors and social anthropologists have invented the figure of the "health promoter".

Educated nurses or more often traditional healers, are trained to the rudiments of the other world's knowledge in order to treat the patients in the remote and isolated jungle, with a very scarce pharmacopoeia but with the infinite resources of the forest.

They have to choose with are the most appropriate remedies and techniques according to the patient's problem and to his beliefs. The first real doctor lives at a several hours or days on a canoe… However thankfully, the more critical cases can be evacuated by helicopter.

For the Quichua people, who are sedentary farmers, as well as for the nomads Waoranis, last Amazonian people who accepted to be in relation with the "civilisation", it is a real revolution.
