Cascara

Cascara (Rhamnus purshiana), a native perennial shrub or small tree, is found in the Pacific Northwest, including British Columbia, California, Idaho, and parts of Mexico. Thriving in moist environments with light to partial sun, cascara can grow up to 10 meters tall. Known for its medicinal properties, cascara has been traditionally used by indigenous peoples for digestive health, particularly to support constipation. A decoction of the bark is commonly prepared and consumed. Cascara adapts well to various soil types, including light sandy, medium, and heavy clay, and is hardy in zones 6. This plant is also beneficial for attracting insects and can serve as a hedgerow or provide wildlife habitat. While cascara is not edible, its medicinal use should be approached with caution, as it contains compounds that can have strong laxative effects.
