Development Studies of Cuticle Drugs from Natural Resources. I. : Effects of Crude Drug Extracts on Hair Growth in Mice

Abstract

Effects of 50% ethanol extracts from 14 crude drugs on hair regrowth in normal and high butter diet-pretreated mice which removed the abdominal hair were investigated.The 50% ethanol extracts of Polygonum multiflorum (I), Drynaria fortunei (II), Panax japonicum (VII) and Swertia japonica (XI) showed the promoting effects on hair regrowth in normal mice.I and VII were effective on hair regrowth in high butter diet-pretreated mice.These results suggested that I and VII promote the hair regrowth and could be used as a hair tonic.
