Used from ancient times for medicinal purposes, liquorice is a plant that belongs to the pulse family and contains glycyrrhizic acid as its main constituent. Although known for its anti-inflammatory and anti-allergic properties, glycyrrhizic acid has also been reported to have reactive oxygen production and male-hormone action suppressing effects. In addition, “oil-soluble liquorice extract” produced from oil-soluble constituents contains large quantities of flavonoid and has been proven to demonstrate skin-whitening, hair restoration, antibacterial, anti-oxidation, reactive oxygen eliminating (SOD-like effect) effects and other properties.
