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.

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, 2,5-dimethyl-7- hydroxychromone, 7-hydroxy-4-methoxy-5-methylcoumarin, flavonols, polysaccharides, and condensed tannins.

Regulatory Status:
Under U.S. law, huzhang extract is regulated as a dietary supplement. As of this writing, no European governments had issued monographs or regulations for nutraceutical uses of huzhang.

NOTE: The statements in this publication have not been evaluated by the FDA.

Indications and Uses:

Studies suggest that resveratrol has anti-atherosclerotic activity and that it might have some immune-stimulating and anti-cancer effects. Human studies are few in number and inconclusive due to short duration and poor design.
