A bioassay-guided technique has been used to isolate anti-inflammatory compounds from the dried rhizomes of Polygonum bistorta, for structural identification. Anti-inflammatory activity was detected using the carrageenan-induced rat paw oedema. Two compounds were isolated which significantly

Extracts of different polarity from four Argentine medicinal plants used in folk medicine as antiinflammatory remedies were tested for bioactivity using carrageenan-induced paw edema in rats and TPA-induced ear edema in mice. A dichloromethane extract from Pluchea sagittalis showed good

BACKGROUND Polygonum hydropiper L. (Polygonaceae) has been traditionally used to treat various inflammatory diseases such as rheumatoid arthritis. However, no systematic studies on the anti-inflammatory actions of Polygonum hydropiper and its inhibitory mechanisms have been reported. This study is

Despite the extensive use of Polygonum chinense (PC) as a detoxifying ingredient of Chinese cool tea, the efficacy of different PC varieties remains underexplored. Herein, we compare the chemical profiles and antioxidant/anti-inflammatory activities of the aqueous extracts of two PC varieties,

Anti-inflammatory studies were conducted on a hot water decoction and on an ethanol extract of the stems of Polygonum glabrum. Effective anti-inflammatory activity was demonstrated against acute carrageenan-induced paw oedema, exudate and granuloma formation in the granuloma pouch test, acute and

Polygonum tinctorium Lour (indigo plant) has been regarded as a useful medicinal plant for traditional herbal medicine. The polyphenolic fraction of indigo leaves exhibited anti-inflammatory activities as determined by the suppressed synthesis of nitric oxide (NO) in cultured RAW264 macrophage

The antibacterial and anti-inflammatory activities, and protective effects of extracts (flavonoid glycosides) of Polygonum capitatum were investigated to detect the evidence for the utilization of the herb in the clinical therapy of gastritis caused by H. pylori. A mouse gastritis model was
