Traditional
Andmodernuses:
Huzhang ("tiger cane") or 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.
Pharmacology:
In animal experiments, huzhang has exhibited antitussive,
antihistaminic, hypotensive, vasodilating, cytotoxic, and
antioxidant properties, among others. Huzhang is also a
concentrated source of resveratrol (3,5,4¡Â-trihydroxy stilbene),
an antioxidant phenol produced in response to fungi. Resveratrol
has also shown antimutagenic activity in bioassays conducted on
bacteria in vitro (umu and Ames tests). 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 (antiinitiation); 2) mediate
anti-inflammatory effects and inhibit cyclooxygenase and
hydro-peroxidase (antipromotion); and 3) induce human
promyelocytic leukemia cell diferentiation (antiprogression).
Resveratrol was also found to inhibit the development of
preneoplastic lesions in vitro and tumorigenesis in vivo. Very
recently, it was reported that Huzhang extract is one of the best
active-oxygen scavengers for the prevention of skin aging induced
by UV-irradiation and free radical. Experiments conducted in vivo
indicate that resveratrol is a potent vasodilator and inhibitor
of platelet aggregation. Recent work in dogs and humans indicate
that other concentrated sources of resveratrol (i.e., red wine
and grape juice) eliminate cyclic blood-flow reductions caused by
platelet-mediated thrombosis.
Active Compounds:
Huzhang is characterized by anthraquinones and their glycosides,
napthoquinone, 3,5,4¡Â-trihydroxy stilbene (i.e., resveratrol),
piceid, fallacinol, citreorosein, questin, questinol,
protocatechuic acid, (+) catechin, 2,*-dimethyl**-
hydroxychromone, *-hydroxy**-methoxy**-methylcoumarin, flavonols,
polysaccharides, and condensed tannins.
