Buckthorn Bark (Rhamnus frangula)


Buckthorn bark contains compounds called anthraquinones, which have a strong purgative, laxative effect on the body. Because these compounds are powerful, before being processed into laxative products the bark is aged for a year, or heated and dried.

Buckthorn, Rhamnus frangula L. [Fam. Rhamnaceae], also known as Frangula, Arrow Wood, Persian Berries, and Black Alder Bark, is native to Europe, the Mediterranean, northwest Asia, and northern Africa. The bark is primarily used for constipation and for conditions that require a softened stool such as hemorrhoids, anal fissures, and after rectal-anal surgery.
