Senna and Constipation : Senna may relieve constipation by stimulating the muscles of the colon to push fecal matter through more quickly. Active compounds in the senna plant, called sennosides, may be responsible for its laxative effect.
Stool-softening Properties : Senna leaf acts on the intestinal walls, causing contractions that lead to bowel movements. In this regard, it can be used to effectively relieve even the most severe cases of constipation. Because of its glycoside content, which helps transport electrolytes, it helps to cleanse the colon creating a bowel movement .
Soothing Anal Fissures and Hemorrhoids: Anal fissures occur when the rectum has split close to the sphincter, causing pain during bowel movements. Because senna leaf helps to soften the stool, it makes defecation less painful when lacerations or other painful obstructions are involved, such as hemorrhoids. Because senna leaf is an anti-bacterial and anti-inflammatory, it also helps to reduce swelling due to irritation, thus helping to soothe the area back to health.
