What is senna? What is it used for?

 சிறுவர்களாக இருந்த போது நம் தாயார் நமக்கு பேதிக்கு கொடுப்பார்களே! ஞாபகம் இருக்கிறதா?

Senna is a shrub found throughout India, Pakistan, and China. Its name is derived from the Arabic word "sena," and it has been used in Ayurvedic and Unani medicines since the ninth century. The shrub grows to a height of approximately two feet, with green stems and pods and yellow, scoop-shaped leaves. The leaves and pods, or fruit, are used medicinally.

The active substances in senna leaves and fruit are called sennosides. These molecules are converted by bacteria in the colon into another substance, rhein-anthrone, which has two beneficial effects. First, it stimulates colon activity, which speeds up bowel movements and improves digestion. Second, it increases fluid secretion.

Traditionally, senna was used as a laxative and was considered a "cleansing" herb because of its cathartic properties. More modern studies have found that senna is useful in treating constipation, whether it is caused by pharmaceuticals or natural means. It may also be used to treat skin conditions such as ringworm and acne.

How much senna should I take?

Some practitioners recommend taking an herbal extract that contains 20-60mg of sennosides per day.

Sennas have for millennia played a major role in herbalism and folk medicine. Alexandrian Senna (S. alexandrina) was and still is a significant item of trans-national trade e.g. by theAbabdeh people and grown commercially, traditionally along the middle Nile but more generally in many regions around the northwestern Indian Ocean.

Sennas act as purgatives and are similar to aloe and rhubarb in having as active ingredients anthraquinone derivatives and their glucosides. The latter are called sennosides orsenna glycosides. Senna alexandrina is used in modern medicine as a laxative;^[13] acting on the lower bowel, it is especially useful in alleviating constipation. It increases theperistaltic movements of the colon by irritating the colonic mucosa. The plants are most often prepared as an infusion. Senna glycosides are listed as ATC code A06AB06 on their own and A06AB56 in combined preparation

Senna is a herb that is generally used for its laxative properties. Senna is also known as cassia senna, wild senna, cassia marilandica, or locust plant. It works by interacting with the bacteria in the digestive track, resulting in intestinal contractions. These contractions are caused by the anthraquinone that is contained in senna. These dimeric glycosides anthraquinone derivatives are known as Senna glycosides or sennosides. They are named after their abundant occurrence in these plants of the genus Senna. The main forms of these glycosides are often referred to by: A, B, C & D. Both leaves and pods of the senna plant are used for their laxative effects. The pods are less potent than the leaves.

Senna is found in many tropical countries. The plant has been used in India for thousands of years as a laxative. It can be found in capsule and tablet form, tea bags and loose tea, as well as liquid extracts. The undiluted dried root can be found in health food stores.
