Anti-Constipation Effects Of The Senna Herb
In late 2002, the U.S. Federal Drug Administration decided to restrict the sale of aloe and cascara products which were being marketed for laxative purposes. After this, senna became the sole surviving class of herbal laxatives being sold on large scale in the U.S. The plant has its origins in the East African region and Middle East, but can also be found in more temperate locations.
