About Senna

Senna has been grown for use as a laxative since ancient Egyptian times. After being ground to a fine powder, senna undergoes a scientific "standardization process" to ensure consistent potency with every recommended dose.

References to the use of senna as a natural vegetable laxative go back 3,500 years to the days of the pharaohs. It is even mentioned in the Ebers Papyrus, which documents medicines used to treat Egyptian royalty. Our Senokot® Family of Laxatives contains only purified and standardized senna.

These studies encompassed a wide variety of subjects, including:
