Laxative Properties Of The Senna Herb

By Kerry Needham


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.

The word senna itself has an interesting history rooted in the Semitic languages, as befitting its origins. It's also known by another equivalent name, cassia. Both are commonly used. It's active ingredient is a chemical or a class of chemicals known as the anthraquinoids. Anthraquinones are found in other types of laxatives. They have the effect of stimulating movement in the intestinal tract.

Given our knowledge about the origins of the name and where the plant comes from, we may not be so surprised to learn that senna has been used for many hundreds of years. Lacking the modern engineering methods of production, it was used in an unprocessed form. However, consumers now can buy it in bottles of capsules which are easier to take.

Though it's thought of as an herbal treatment, a prospective consumer should be aware of the history and quality of the producing company. Natural laxatives can be dangerous even if they are natural. Prospective consumers should consult with organizations who monitor the quality of such companies to ensure that they have not had serious breaches of business ethics or been embroiled in disputes of quality. Allergic reactions are rare but should be kept in mind.

Continuing on the theme of safety, a consumer is advised to be aware that there are specific warnings that accompany senna. Some studies have raised the point that people who suffer from heart disease or high blood pressure can be adversely affected by senna. These observations suggest that any patient with constipation should ask for the help and guidance of a personal physician prior to starting any kind of treatment.

In times of antiquity, senna was likely to be ingested while in herbal or leaf form. Some people will find this to be the most pleasing way of taking senna. In response to such demand, manufacturers have made a tea form of the senna laxative. However, sophisticated formulations such as capsules and tablets can be more nutritious if they are fortified with minerals like calcium.
