Many people who do not want to deal with the strictures of a diet turn to alternative measures to facilitate weight loss. Supplements and herbal remedies have been embraced as a way to shed pounds, and senna is one route choosen by some. Both the leaves and fruit of this herb are used medicinally. Senna has been used to treat constipation, irritable bowel syndrome, hemorrhoids and to affect weight loss.
Function
Well known for its laxative properties, senna initiates a laxative effect by irritating the lining of the bowels. This is due to the presence of chemicals known as sennosides. Sennosides are hydroxyanthracene glycosides, which are stimulant laxatives. Stimulant laxatives promote increased contraction of the muscles in the bowels that cause the movement of stool. The ability of senna to empty the bowels has been instrumental in leading to its use for weight loss.
Where to Find Senna
The senna plant can be found in many different parts of the world, and is commonly available in teas marketed as weight loss aids. These teas are touted as causing rapid weight loss. Many drug stores and retail stores stock senna-infused teas, although senna can also be obtained in capsule form.
FDA Approval
The U.S. Food and Drug Administration has approved the use of senna as a nonprescription laxative, to be used for treating constipation. While it is used for other conditions and purposes, including weight loss, there is insufficient evidence to prove any long-term benefits.
Potential Problems With Senna
Long-term use of senna can lead to electrolyte depletion. Diarrhea can result from over-use of this product, causing dehydration. These are problems that may occur if senna is used for weight loss. Changes in the body's electrolyte balance can cause serious health issues such as liver damage, heart problems and muscle weakness.
Considerations
It is recommended that senna not be used for longer than two weeks. Like any laxative, extended use may cause the bowels to stop functioning on their own. This means you may no longer be able to have bowel movements without the aid of a laxative.
