What is senna?
Senna is an herb that is also called Alexandrian Senna, Casse, Fan Xie Ye, Indian Senna, Khatoum Senna, Sen, Sena Alejandrina, Sennae Folium, Sennae Fructus, Sennosides, Tinnevelly Senna, True Senna, and other names.
Senna is likely effective in alternative medicine as a help for occasional constipation in adults and children who are at least 2 years old.
Senna has been used in alternative medicine as a possibly effective aid for emptying the bowel before a colonoscopy.
Other uses that have not been proven by research include weight loss, irritable bowel syndrome, hemorrhoids, and other conditions.
It is not certain whether senna is effective for treating any medical condition. The medicinal use of this product has not been approved by the FDA. Senna should not be used instead of medication prescribed by your doctor.
Senna is often sold as an herbal supplement. There are no regulated manufacturing standards for many herbal products, and some supplements that are marketed have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be bought from a reliable source to reduce the risk of contamination.
Senna may also be used for purposes not mentioned in this product guide.
