Senna: properties and benefits

Known as a laxative, senna has historically also been used to kill worms, and to purify the body.

This herbal tea has properties thanks to the substances contained in the senna leaves, which interact with bacteria in the digestive tract.

These are substances called dimeric glycosides , derivatives of anthraquinone, known as senna glycosides or sennosides. They act with a slight irritation, which causes the intestinal muscles to contract and gives the laxative effect. Both the pods and the leaves of the senna are used for their laxative effects via these substances, but the leaves are more potent.

Glycosides are a group of organic compounds commonly found in plants that work to move muscles as digested food moves through the intestines.

The contraction helps to increase the volume of stool and move it out of the colon, creating the purgative effect.

The whole process is caused by the chain of fatty acids that help digestion and fermentation, until the glycosides are converted into a laxative agent.

For this reason, Senna leaf tea is generally used by people suffering from constipation . Bowel movement should occur within 6-12 hours.

It is recommended to take before bed, so that relief against constipation can occur in the morning.

It is important not to use senna for more than a week, otherwise the leaves of the plant can irritate the intestinal walls.

Obviously, prolonged use can cause inflammation of the intestinal tract, episodes of diarrhea or vomiting.

Its beneficial properties also serve to counteract abdominal bloating and flatulence.

The purgative properties of senna leaves can be effective in treating digestive system disorders, including indigestion. They promote gastric emptying of the stomach and calm the intestinal tract, reducing acid in the stomach.

The herbal tea can also be useful to treat hemorrhoids or inflammation of the veins surrounding the part, due to excessive pressure. By reducing inflammation, it can promote relief, and easier final transit.
