Ian told me about how after the Secoya were taken as slaves, they eventually killed their "masters" and escaped and established a colony in the Peruvian jungle. The two parts of the tribe had no contact for roughly 60 years.
In the early 2000's, a scientist studying their plant knowledge in Ecuador had an unusual experience during a Yage (Ayahuasca) ceremony where he became telepathically connected to a tribe elder who was preoccupied with the thought of a boat.
"Why do you keep thinking about a boat?" He asked. And the tribe elder told him there might was lost part of their tribe in Peru that could only be reached via the river. But it was only a legend...
So, that scientist, Shawn Chaffin, raised money to buy them a boat, and sure enough they found and connected with the "lost" part of their tribe. Amazing, right?
Since then, he and an organization called Amazon Frontlines have been working with the Secoya to gain legal recognition by the Ecuadorian government and reclaim their ancestral land, restoring it to people dedicated to protecting it from the surrounding oil fields, mega-scale African Palm plantations and a network of roads that accelerate illegal logging and land invasion.
Many of their plant medicines have never even been catalogued let alone studied by modern science, and both their traditional ways and the rich and important ecosystem the inhabit could be easily lost without our help.
