Cascara is a shrub. The dried bark is used to make medicine.
- Traditional/Ethnobotanical uses: Cascara was a folk medicine used by native American people and immigrants as a natural laxative. The plant itself was not definitely identified by scientists until 1805, and the bark was not commonly used as medicine 1877.
- General uses: Limited clinical studies exist for cascara aside from those of its laxative effects. Attention has shifted to studying the effects of its constituent emodin, particularly with regard to possible therapeutic applications in the treatment of cancer.
- Cascara used to be approved by the federal Food and Drug Administration (FDA) as an over-the-counter (OTC) drug for constipation. However, over the years, concerns were raised about cascara’s safety and effectiveness. The FDA gave manufacturers the chance to submit safety and effectiveness information to answer these concerns. But the companies decided the cost of conducting safety and effectiveness studies would likely be more than the profit they could expect from sales of cascara. So they didn’t comply with the request. As a result, the FDA notified manufacturers to remove or reformulate all OTC laxative products containing cascara from the U.S. market by November 5, 2002. Today, you can buy cascara as a “dietary supplement,” but not as a drug. “Dietary supplements” don’t have to meet the standards that the FDA applies to OTC or prescription drugs.
