Cascara sagrada is found in many herbal laxative formulas. It is also included in many colon cleansing products and internal cleansing kits. Although most herbs are considered safe, just because something is natural does not always mean it is completely harmless.
History
The cascara tree, also known as chittam, bearberry or buckthorn, can be found throughout western North America. It has been used by Native Americans for more than one thousand years to treat constipation. The name cascara sagrada is Spanish for sacred bark. The dried bark of the tree is the part used in herbal remedies. It must be aged for one year before it can be ingested. Fresh cascara has harsh purgative effects.
Features and Uses
Cascara sagrada bark is used in herbal medicine for its natural laxative properties. According to Clayton College of Natural Health, it is safe for long-term use, and generally does not cause dependency as with over-the-counter laxatives. It is naturally antibacterial and a natural chelating agent, meaning it binds with toxins. In addition to treating constipation, cascara has been used by herbalists to treat liver disorders and gallstones.
Expert Insight
Although research published in Alternative Therapies in Women's Health states that laboratory studies do not indicate the herb to have carcinogenic (cancer-causing) effects, the University of British Columbia notes that some species of cascara has been shown to have toxic effects on livestock. Most herbalists agree that cascara sagrada, when taken in moderation, is an effective treatment for the relief of occasional constipation. However, it should be noted that in 2002, the FDA banned the use of cascara in over-the-counter medicinal laxative products.
Warnings
As with most herbal remedies, scientific research on cascara sagrada is somewhat limited. While herbalists claim that because it has been part of native folk medicine for over a thousand years, and ample empirical evidence supports the use of cascara in the treatment of occasional constipation, medical specialists point out that more research is needed on potential toxicity to allow prescribing the herb for long-term use. Ingesting large doses of cascara sagrada can cause nausea, cramping as well as diarrhea.
Considerations
Those suffering from chronic constipation may or may not benefit from trying cascara sagrada. However, as with many chronic issues, there is most likely an underlying problem that needs to be addressed, such as irritable bowel syndrome (IBS) or colitis. Taking cascara or other laxatives, herbal or medicinal, is not a permanent solution for chronic constipation. Dietary and lifestyle modifications may need to be used in conjunction with medicine. Always consult a physician or healthcare professional before trying herbal remedies. Holistic medicine should be used in conjunction with, and not in place of, traditional medical treatment.
