|Senna is used in the treatment of constipation and acts through stimulation of intestinal peristalsis (contractions). It is important to recognize that constipation is sometimes caused by factors which should be corrected prior to the regular use of a strong cathartic like senna. Short-term use only is recommended without a doctor's supervision, as cathartics can become habit-forming.|
When stimulant laxatives such as senna or Cascara sagrada have been used for a long time, stopping the medication may result in severe constipation. You may need to "retrain" your bowels in order for them to function naturally by gradually lowering the nightly dose of senna. This may take longer than a month to accomplish.
