Yunnan Paiyao is a Chinese herb mix renowned for its ability to reduce bleeding, as well as to provide pain relief, reduce inflammation, and promote wound healing. Developed in early 1900s Yunnan Province, China, the secret blend gained attention when it was carried by foreign soldiers as a hemostatic agent. Analysis of the mix indicates it contains mainly Panax notoginseng root, 94% starch, calcium, and phosphorus. Scientific studies demonstrate that Yunnan Paiyao sharply diminishes bleeing and clotting time.
