    Legends, Myths and Stories

    California buckthorn (cascara sagrada) is still the most effective laxative known. It has also been used for gallstones and liver ailments.

    Coffee berry (cascara sagrada), “Ae buck oko,” Warms Springs, Oregon. California Native Americans used it also. The bark was peeled back towards the ground; used for a physic.
    The bark is very bitter and disagreeable to the taste of many people.

    In Europe, Rhamnus frangula was being used for its laxative properties. In remote sections of the northwest, Native Americans were using Rhamnus purshiana for laxative. As the Europeans eventually came in contact with the Native Americans of the northwest they learned about the new variety of Rhamnus. They recognized it as a superior variety and eventually replaced the old world variety for the Native American variety. It is better known today as Cascara Sagrada.

    While the Native Americans did not know the chemical constituents of their medicine plants, centuries of experiment taught them the hidden virtues. They knew just what season an herb contained its fullest properties. They knew that an herb found growing in certain soils and locations was superior medicinally to the same plant growing in an unfavorable location. They believed that bark growing on the sunny side of trees was stronger than bark found on the shady side. They knew what part of the plants were best used and applied them in the manner most effective. The Native Americans understood the strength of their medicines. This is remarkably evident when they used such drastic medicine as Poison Oak, Poison Ivy, Poison Hemlock, and Stramonium. They were taken internally for certain conditions with counter-balancing botanicals in special doses.

    In Colonial times and early pioneer days, the settlers often went to the Native American medicine man for help. Today many of these old Native American medicines are recognized and used by herbalists. Modern chemistry has proved how remarkable and correct the majority of the Native Indian remedies were used.

    Missionaries called the bark found in Native American belongings Cascara Sagrada or Holy Bark, believing it to be the Chitemwood of the Bible.

    The United States Dispensatory states: “Cascara Sagrada belongs to the group of vegetable cathartics whose activity depends upon the presence of one or more hydroxymethulanthraguinones–in the treatment of chronic constipation it acts very favorably. It often appears to restore tone to the relaxed bowel and in this way produces a permanent beneficial effect.”

    Herbalists generally believe best results are obtained when Cascara is mixed with other herb simples.
