History of Senna
The use of Senna dates back over a millennium, with records as early as the 9th century, when it was consumed as a tea or in powdered form for its medicinal effects.
Native regions like Northern Africa, parts of the Middle East, and southern India, senna's name stems from Arabic origins. The first documented medicinal use comes from renowned Arab physicians. In Traditional Chinese Medicine, send has been recommended to address constipation, atherosclerosis, and to "clear heat" in the liver while "brightening the eyes."
In Ayurvedic traditions, it's known for treating conditions like anemia, jaundice, and bronchitis. Beyond these, traditional uses also extend to treating dysentery, ringworm, fever, hemorrhoids, wounds, and skin conditions like dermatitis.
Over centuries, these diverse uses have cemented Senna as a trusted herbal remedy across cultures. Today, it remains a widely used, natural laxative and detoxifying agent, reflecting centuries of traditional wisdom.
Health Benefits of Senna
Today, senna is almost exclusively used for the treatment of constipation. Its active constituents, anthranoid glycosides, are initially inactive while they pass through the stomach and small intestine. Once these compounds reach the large intestine, however, they are activated and irritate the intestinal lining causing the muscles in the intestinal wall to contract vigorously and rhythmically in waves. Fluid uptake by the cells of the large intestine is also prohibited by these glycosides, allowing for soft and easily passed bowel movements.
Senna Supplement Information
The recommended daily intake of Senna is 600 mg – 2 grams/day, and it should always be taken with water. As with any fibre supplement, it can alter the absorption of many supplements as well as prescription and OTC medications. Take away from these items.
Cautions & Considerations
Senna is such as powerful laxative that it can cause sharp stomach pains and cramping even at recommended dosages. It is often combined with ginger, mint or cinnamon to relax the muscles of the stomach and gastrointestinal tract and prevent cramping. These herbs also make senna more palatable, as it has a bitter taste which most individuals find unpleasant.
If used chronically, senna can cause electrolyte imbalances, and dependency. It is not recommended for long-term use and should always be used under the guidance of a healthcare provider.
