Chongcao is literally translated "bug-grass," and is vital for Tibetans in this area. It's a cash crop they don't plant, but harvest every year high above the tree line. Starting as a caterpillar, this worm burrows down into the ground and dies, then a fungus grows out of the caterpillars body and is harvested as traditional medicine. Locals can make much of their yearly income by harvesting and trading this unique "bug-grass" Don't worry, no bugs are included with this blanket, but you may need it if you go live up at 15,000 ft. for a season to harvest chongcao!
