Abstract
We investigated the effects of a Korean traditional prescription, Geiji‐Bokryung‐Hwan (GBH) consisting of five herbs of Cinnamomi Ramulus (Korean name Geiji), Poria cocos (Bokryung), Moutan Cortex Radicis (Modanpi), Paeoniae Radix (Jakyak) and Persicae Semen (Doin) on tumor growth‐inhibitory activity and cancer chemopreventive activity in assays representing three major stages of carcinogenesis. Effects of the GBH extracts on carrageenan‐induced edema inflammation using female (C57BL/6XC3H) F1 (B6C3F1) mice and tumorigenesis were examined. Finally, cyclooxygenase metabolites were determined after extracts treatment. These data suggest that GBH extracts merits investigation as a potential cancer chemopreventive agent in humans.
