KathmanduTharu healers’ oral knowledge has no written archive.
Sanjib Chaudhary’s audio-visual project for the Wikimedia Foundation captures healer voice and gesture that written records lose — knowledge passed healer to healer for generations.
The project begins with 2 healers in Saptari and plans to expand across Nepal.

WHO THE THARU ARE
The Tharu are an indigenous people of the Terai lowlands along Nepal's southern border with India, numbering roughly 1.7 million in Nepal. They are known for a historic genetic resistance to falciparum malaria — which is why they settled and farmed the malarial Terai when surrounding hill populations could not.
WHY ORAL KNOWLEDGE RESISTS PAPER
Healer knowledge is not just a list of plants and doses. It is gesture, intonation, the precise way a leaf is crushed, the song sung while it steeps, the diagnostic conversation with the patient. Written ethnobotany strips all of this and keeps only the ingredient list — which is why pharmacological extractions from indigenous compendia so often fail to reproduce the original effect.
THE BIOPIRACY PRECEDENT
In 1995 the US Patent Office granted a patent on turmeric's wound-healing properties to two researchers at the University of Mississippi. India's CSIR challenged it by submitting Sanskrit and Urdu texts dating back centuries. The patent was revoked in 1997 — the first successful traditional-knowledge patent challenge — and triggered the creation of India's Traditional Knowledge Digital Library, now consulted by patent offices worldwide before granting plant-based claims.
THE NAGOYA PROTOCOL
The 2010 Nagoya Protocol to the UN Convention on Biological Diversity established that indigenous communities have the right to free, prior, and informed consent before their genetic resources or associated knowledge are used, and the right to share in any benefits. Nepal ratified in 2018. The protocol is why a modern healer-knowledge archive must address consent and benefit-sharing upfront — not bolt them on after publication.
WHAT GETS LOST WHEN A HEALER DIES
Ethnobotanists estimate that a single experienced healer carries working knowledge of 200-500 plant preparations. UNESCO's 2003 Intangible Cultural Heritage Convention exists because this knowledge disappears at the speed of a generation — once the last practitioner of a tradition dies without transmission, the loss is permanent and uncopyable. Two healers in Saptari is a small start against a steep curve.
THE CONSENT ARCHITECTURE
Wikimedia projects use Creative Commons licenses, which assume the contributor owns what they upload and can release it to the world. Indigenous knowledge complicates this — what one healer knows often belongs to a lineage, a clan, or a community, not an individual. The hardest design question for any healer archive is not the recording technology but the licensing layer above it.
