Senna
Senna, also known as narrowleaf senna (Cassia angustifolia M. Vahl.), is a legume-family plant traditionally used to support healthy digestion. Supplement makers typically use its leaves and pods, valued for natural compounds that help stimulate bowel movement and keep digestion running regularly.
What are the benefits of senna?
-
Promotes healthy bowel motility
-
Helps maintain regular bowel movements
-
Supports normal digestive function
-
May help relieve occasional constipation
-
Supports the body's natural bowel-cleansing process
Senna leaves tend to have a stronger effect, while the pods work more gently.
When can senna help?
Senna may help when digestion slows down and you notice:
-
Bowel movements are less frequent than usual
-
Difficulty passing stool normally
-
A feeling of fullness or heaviness in the abdomen
-
A sense of "stagnation" in the digestive system
Natural sources of senna
Senna (Cassia angustifolia M. Vahl.) grows naturally in warm, arid regions — especially India, North Africa, and the Middle East. Its leaves and pods are the parts most commonly used to make supplements and teas, including capsules, tablets, powders, and herbal tea blends.
Recommended senna dosage
Senna leaves are typically used in smaller amounts because of their stronger effect, while pod-based preparations are usually chosen for a gentler effect. The typical recommended daily dose is around 10-30 mg of sennosides, depending on the product's composition and concentration. The right dose should be chosen individually, taking into account bowel sensitivity, how long it will be used, and overall health.
Possible side effects of senna and interactions with medications
Because of their stronger effect, senna leaves are more likely to cause abdominal cramping, discomfort, or diarrhea in sensitive individuals, while the pods tend to act more gently. Long-term use isn't recommended, as it may disrupt the body's fluid and mineral balance and lower potassium levels. If you're taking diuretics, heart medications, or other laxatives, talk to your doctor before using senna.
