Senna is a herb that comes from a family of flowering plants known as Cassia. In Ayurvedic medicine it is known as Markandika. It can be found in the form of tea, liquid, powder as well as tablets. It is a powerful herb that is used to treat constipation. It has also been suggested for use as a blood purifier as well as to treat skin diseases. Recently, it has also been used for weight loss. However, more research is required for Senna’s uses other than as a laxative. But why should pregnant women avoid Senna, especially in the first trimester of pregnancy?
Senna acts by irritating the cells in the colon which stimulates movement in the intestines, providing a laxative effect. The active ingredient in Senna called Senna Glycosides or sennosides are added in many over-the-counter laxatives. However, taking Senna while pregnant may lead to contractions in the uterus and poses an increased risk of premature labour. Pregnant women may also experience abdominal pain, cramps in the stomach, discomfort and diarrhoea. Diarrhoea during pregnancy can cause excess fluid loss, leading to electrolyte imbalance. Therefore, Senna should be avoided in the first trimester of pregnancy and thereafter consumed only after consulting your doctor.
