Cleaning caterpillar fungus

Women sort, clean, and dry caterpillar fungus (冬虫夏草 dōngchóngxiàcǎo), also known as Himalayan Viagra, in Xining, the capital city of Qinghai Province. The fungus is pricey, as many people believe that it has health benefits. However, a recent paper published by the international journal Cell Chemical Biology concludes that caterpillar fungus does not have any anti-carcinogenic properties.
