What is black draught laxative syrup made of?

Senna, a plant-derived laxative, is the main component of black draught laxative syrup. Senna is a stimulant laxative that works by speeding up the movement of waste through the digestive tract. Senna is combined with other ingredients in black draught laxative syrup, such as licorice, peppermint, and ginger, to form a potent laxative. These additional components have a calming and soothing effect on the digestive tract, assisting with the unpleasant side effects of taking laxatives.
