The Matsés have only printed their encyclopedia in their native language to ensure that the medicinal knowledge is not stolen by corporations or researchers as has happened in the past. Instead, the encyclopedia is meant as a guide for training new, young shamans in the tradition and recording the living shamans' knowledge before they pass. "One of the most renowned elder Matsés healers died before his knowledge could be passed on so the time was now. Acaté and the Matsés leadership decided to prioritize the Encyclopedia before more of the elders were lost and their ancestral knowledge taken with them," said Herndon. Acaté has also started a program connecting the remaining Matsés shamans with young students.
