 "The bark (and to a lesser extent the fruit) has been used as a laxative, due to its 3 - 7% anthraquinone content. Bark for medicinal use is dried and stored for a year before use, as fresh bark is violently purgative; even dried bark can be dangerous if taken in excess."​ [[http://​en.wikipedia.org/​wiki/​Rhamnus_frangula]] "The bark (and to a lesser extent the fruit) has been used as a laxative, due to its 3 - 7% anthraquinone content.

-The unpleasant smelling (german name "​Faulbaum",​ rotting tree) wood brakes easily, hence the latin name "​Frangula"​ from "​frangere"​ = to brake. In spring the bark is most readily seperated from the twigs  and then air-dried during one year or heated for some hours to convert anthrones to anthraquinones. The dried bark contains up to 8% of 1,​8-antraquinones mostly glycosidically bound. Important compounds are glucofrangulines A and B, as well as the frangulines A and B (during storage increasingly emerging), all of which derived from the same aglycon, frangulaemodin. There are also small amounts of chrysophanol,​ physcion and dianthrones as glycosides.
