• In an unprecedented participatory ethnobotany approach, Hemerson Dantas dos Santos Pataxó HãHãHãi, a Brazilian Indigenous ethnobotanist, documented alongside his people their traditional medicinal practices: cataloging 175 medicinal plants, many of which had their use reaffirmed in scientific literature.
• Mongabay visited Hemerson and spoke with several Indigenous elders who survived violent land conflicts about their medicinal knowledge and their efforts to protect it in the Caramuru/Paraguassu Indigenous Territory, a land illegally occupied by cattle farmers for decades in Brazil’s Bahia state.
• Samples of plants collected by Hemerson are being kept at an internationally registered herbarium, and he’s finalizing a book in the hope of keeping the knowledge of the species and ancestral healing practices alive for his people’s future generations.
• The work carried out with his people was essential to make “immortal” the knowledge of the elders, Hemerson said, describing them as “living libraries” and “Guardians of Memories.”
