Pulsatillae Radix, the root of Pulsatilla koreana Nakai (Ranunculaceae), has been traditionally used as a remedy for leukorrhea and amoebic dysentery by taking internally‘ and as an antimicrobial for external use. We carried out this study to examine the anti-dandruff effect of 70% Ethanol-Extract of Pulsatillae Radix (EPX) compared with 1 % zinc pyrithione used commercially as anti-dandruff. The EPX showed significant antimicrobial activity against Pityrosporum ovale, major cause of dandruff, and also showed significant anti-dandruff and itch-improvement effect of head skin.
