  • Publication number: 20160213605
    Abstract: A composition comprising an extract of combined herbs Acanthopanax koreanum Nakai and Crinum asiaticum var. japonicum showing treatment activity of a hair baldness disorder and stimulating activity of hair growth. The combined extract showed potent hair-growth promoting activity and a synergistic effect compared to each herb, i.e. the sole treatment of Acanthopanax koreanum Nakai or Crinum asiaticum var. japonicum, through animal model experiments, such as, the growth rate test using C57BL/6 mouse, to confirm the effect of the combined extract, i.e. combined treatment of Acanthopanax koreanum Nakai and Crinum asiaticum var. japonicum. Therefore the extract can be useful in treating a hair baldness disorder.
