Barberry is traditionally used as a tonic, purgative, antiseptic. It is used in the form of a liquid extract, given as infusion or tincture. As a bitter stomachic tonic, it proves an excellent remedy for dyspepsia and functional derangement of the liver, regulating the digestive powers, and if given in larger doses, acting as a mild purgative and removing constipation. It is used in all cases of jaundice, general debility and biliousness, and for diarrhoea.
