Remarks

In common with the Saponaria officinalis, this drug possesses an active principle named Saponin, which is irritant when applied in a concentrated state. It is also anaesthetic. Under the name of "Fluid Extract of Soap-bark," a preparation of the plant is found in the market. Mixed with a few drops of water and briskly rubbed, a lather like that of soap is formed. This we have employed for several years as a cleanser, detergent, and stimulant, and more especially in cases where the ordinary soaps did not agree well with the skin. Mingled with a little glycerine it forms an admirable application in some cases of acne. Mixed with coal-tar it constitutes the "Coal-tar saponine Le Boeuf," a French proprietary preparation.
