Cascara Sagrada Bark (Rhamnus purshiana)

Conventionally oriented physicians recommended Cascara Sagrada to patients suffering constipation after surgery for hemorrhoids. The 1,8-dihydroxy-anthracenes in cascara sagrada act on the nerves in the intestinal tract, numbing the nerves that hold back stool and stimulating the nerves that propel stool downward. If you experience cramping, you?ve used too much.
