Plant Raw Material Introduction
The raw material of this product is the dried small leaves of the Leguminosae plant Cassia angustifolia Vahl or Cassia acutifolia Delile. It is mainly produced in Sudan, India, and the Arabian Peninsula. The 2020 edition of the Chinese Pharmacopoeia (Part I) includes the standard for Senna leaves. Senna leaves are bitter and cold in nature, attributed to the large intestine meridian, with effects of clearing heat and promoting fluids, relieving constipation, and eliminating accumulation. The main active components are Sennoside A and B.
Core Effects
Senna leaf extract has a substantial research basis in constipation management. Its core components, sennosides (Sennoside A & B), can support bowel movements by stimulating colonic peristalsis; for liver health, sennosides can support bile secretion.
Note: Long-term continuous use carries a risk of dependency and is not recommended for prolonged use.
