Before You Use Cascara Sagrada

By

Updated August 26, 2013

Cascara sagrada is an herbal supplement long used by Native Americans for its laxative properties. The supplement is taken from the bark of a species of buckthorn plant, with the botanical name rhamnus purshiana. Cascara sagrada contains anthraquinones, organic compounds known for their laxative effect. Although cascara sagrada is sold over-the-counter, there are important safety risks that you need to know to help you to decide if taking cascara sagrada is right for you.

Is Cascara Sagrada Safe?

Safety information on cascara sagrada is a bit sobering. The Food and Drug Administration (FDA) issued a ruling in 2002 that banned the inclusion of cascara sagrada in over-the-counter products due to safety concerns. Regular use of cascara sagrada has been linked with an increased risk of hepatitis and colorectal cancer.

Safety Recommendations

Cascara sagrada is not recommended for use by pregnant women or children under the age of 12. If you suffer from any type of health problem, it is essential that you get clearance from your doctor before taking cascara sagrada due to potential adverse reactions. Cascara sagrada should not be taken for more than seven days in a row.

The Bottom Line

People often assume that all herbal supplements are safe. Cascara sagrada is a good example of the fact that caution needs to be applied before initiating any form of treatment, even one that is sold over-the-counter. In my opinion, it would be well worth your time to explore alternative treatments for constipation.
