100 results about "Yunnan Baiyao" patented technology

Yunnan Baiyao (or Yunnan Paiyao; simplified Chinese: 云南白药; traditional Chinese: 雲南白藥; pinyin: Yúnnán Báiyào; literally: 'Yunnan White Drug') is a proprietary traditional Chinese medicine marketed and used as a hemostatic product with use in both human and veterinary alternative medicine. There are multiple routes of drug administration. There is limited evidence regarding its effectiveness in preventing or treating hemorrhagic and pathological conditions in both humans and animals via oral administration. The safety and efficacy of Yunnan Baiyao has not been assessed or established by the FDA, European Medicines Agency, or the Australian Therapeutic Goods Administration. In a limited number human studies of small sample sizes, administration of Yunnan Baiyao has been shown to correlate with "reduced perioperative bleeding as well as bleeding in various ulcerative–hemorrhagic conditions" . Yunnan Baiyao is sold in powder, tincture, plaster, paste, aerosol, or tablet form. The medicine, developed by Qu Huangzhang in 1902, is designated as one of two Class-1 protected traditional Chinese medicines which gives it 20 years of trade protection in China. Yunnan Baiyao products are manufactured and distributed by a state-owned enterprise, Yunnan Baiyao Group (SZSE: 000538) in Yunnan, China.
