Illustration of Cascara (Frangula purshiana)

Cascara is a native shrub or small tree of moist Pacific Northwest forests whose bark was collected for use as a laxative drug for over a century. It was so heavily harvested that populations are still reduced across much of its range. Its black berries are an important fall food for many birds including band-tailed pigeons and American robins.
