Senna leaf and fruit are natural products that are primarily used as a laxative for the treatment of
constipation. Senna (in the form of sennosides) is an over-the-counter medication generally recognized as safe and effective for treating constipation.
Senna contains sennosides, compounds that act as a stimulant laxative. It is thought that the product works by irritating the lining of the digestive tract, which causes fluid secretion and helps stimulate movement through the
colon. It has also been suggested that senna may work by affecting prostaglandins or serotonin in the digestive tract.
Because senna (in the form of sennosides) is a FDA-approved non-prescription drug, there are clearly established dosing recommendations for it. The recommended dosage varies, depending on your age.
As with any medicine, side effects are possible. However, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. Serious side effects are less common.
Some of the common side effects include, but are not limited to:
- Abdominal pain
- Cramping
- Bloating
- Gas
- Nausea
- Diarrhea.
