What is the Giant Knotweed Extract?
Giant knotweed is an east Asian species (Polygonum cuspidatum), belonging to the Polygonaceae family. Documented uses in traditional Chinese medicine date to the first century BC, and contemporary medical uses supported by clinical results include acute microbial infections or viral hepatitis, chemo- or radiation-induced leukocytopenia, atherosclerosis, and hyperlipidemia.
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 (antipromotion); And 3) induce human promyelocytic leukemia cell diferentiation.
