Yunnan Baiyao

Yunnan Baiyao (or Yunnan Paiyao) (simplified Chinese: 云南白药; traditional Chinese: 雲南白藥) is a hemostatic powdered medicine famous for being carried by the Vietcong to stop bleeding during the Vietnam War. The medicine, developed by Qu Huangzhang in 1902, is designated as one of two Class-1 protected traditional medicines, which gives it 20 years protection. In China, its reputation is equal to that of penicillin in the U.S. It is founded and manufactured by a state-owned enterprise, Yunnan Baiyao Group (SZSE: 000538) in Yunnan, China.
