It is one of the common names of a shrub's scientific name Frangula alnus (or Rhamnus frangula), of the family Rhamnaceae. It has medicinal uses, especially as a purgative and cholagogue. Also its bark used in tanneries since it possesses strong tannins. It has many other common names of which I relate: Myrtle, Poplar Grove, avellanito, gediondo, ollacarana, tree, rabiacana, ácere and azare.
