Yarsa Rush

Issue #151 27 June – 3 July 2003

People of mountain villages this year also moved to higher elevations for the pre-monsoon yarsa gold rush. Even schools in high mountains shut down to accommodate students going to collect the medicinal fungus which fetches up to $10,000 per kg in China.

Locals do not get much of that money, but even the small amounts they are paid by middlemen makes it worthwhile. It has  lifted the living standard of people in many parts of rural Nepal, allowing them to afford basic healthcare and education. But yarsa harvests are getting slimmer due to over-extraction and climate change. 

Excerpts of a report on yarsa picking in Dolpo published 20 years ago this week in issue #151 27 June – 3 July 2003:

Yarchagumba is known by its Latin name Cordyceps sinesis and is a unique combination of a yellow caterpillar and a mushroom. Few scientists have studied the phenomenon, and its lifecycle is not completely understood. The Tibetan name means 'summer grass, winter insect'. Just before the rainy season, spores of the cordyceps mushroom land on the heads of caterpillars of the Lepidoptera family that live mainly underground. After the fungus buries itself in the caterpillar's body, it works its way out through the unfortunate insect's head. The parasite soaks up the caterpillar's energy until it dies. Yarchagumba can be found when the snow starts to melt between 3,300-4,000m in parts of Tibet, India, Bhutan and Nepal.

It is an intricate network of Kathmandu investors who finance local businessmen who in turn hire subcontractors or buy yarchagumba directly from gatherers. This year the yarchagumba is bought from collectors for Rs 120,000 per kg. Depending on quality and size of the product, the middlemen sell the stuff by the sackload in Thailand, Korea, China and Japan for $2,800 per kg. Japanese scientists, who first came to Dolpa's mountains in a helicopter, have even tried to grow yarchagumba back home in refrigerators to simulate Himalayan conditions. It didn't work.
