Unigen Pharmaceuticals, Inc., Lacey, WA, has received notification of approval of a U.S. patent for Free-B-Ring Flavonoids derived from Chinese skullcap in supporting its novel Univestin joint health ingredient. Univestin is a proprietary blend of two individual ingredients—flavans extracted from Acacia catechu and free-b-ring flavonoids from Scutellaria baicalensis. Earlier patents were issued on the Univestin composition and usage, as well as the flavans extract from Acacia catechu to modulate COX/LOX mediated inflammatory conditions. The newly allowed Free-B-Ring flavonoid U.S. patent will cover this class of natural products from all potential genus and parts of high plants that include Scutellaria genera for treating osteoarthritis.
