Cascara Sagrada. Safe and Powerfully Effective. Revered for centuries for its gentle yet effective detoxifying properties, 100% Pure Botanical Cascara Sagrada, in its only activated form... bark. Sourced from its native country the USA, explorers of the Pacific Northwest discovered native peoples using the bark and gave it the name "Sacred Bark" in honour of its effect. It is believed to be the most widely used cathartic in the world. Ancient Purity's first interest in this Sacred Bark came from the study of Dr. Sebi’s use of it. Cascara Sagrada is a shrub native to western North America first used by the native Indians. The "Sacred Bark" herb is made from the bark of the Cascara Sagrada tree. Like high fibre plant-based foods Cascara Sagrada stimulates peristalsis, this worm-like contraction helps to push waste out of diverticula that compromise the structure of the intestinal function.
