Giant knotweed extract has exhibited antitussive, antihistaminic, hypotensive, vasodilating, cytotoxic, and antioxidant properties, among others. Giant knotweed extract is also a concentrated source of resveratrol, an antioxidant phenol produced in response to fungi. Resveratrol has also shown antimutagenic activity in bioassays conducted on bacteria in vitro. And, in a recent investigation conducted in vivo and in vitro, resveratrol displayed chemopreventive effects at three critical stages of carcinogenesis. Specifically, resveratrol was found to 1) induce phase II drug metabolizing enzymes; 2) mediate anti-inflammatory effects and inhibit cyclooxygenase and hydro-peroxidase (anti-promotion); and 3) induce human promyelocytic leukemia cell diferntiation. Resveratrol was also fond to inhibit the development of prneoplastic lesions in vitro and tumorigenesis in vivo. Very recently, it was reported that Giant knotweed extract is one of the best active-oxygen scavengers for the prevention of skin aging induced by UV-irradiation and free radical. Recent work in dogs and humans indicate that other concentrated sources of resveratrol eliminate cyclid blood-flow reductions caused by platelet-mediated thrombosis....
