Senna obtusifolia
Plante annuelle des Amériques tropicales et mauvaise herbe pantropicale; les graines sont utilisées comme laxatif et substitut de café; les feuilles sont largement utilisées en médecine traditionnelle.
Senna (Senna alexandrina, also known as Cassia senna) is an annual herb native to tropical regions, widely used as a stimulant laxative due to its anthraquinone glycosides (sennosides). Its leaves and pods are employed in traditional medicine for constipation, liver conditions, and as a coffee substitute. Key active compounds include sennosides, emodin, chrysophanol, and flavonoids.
Sennosides are prodrugs that are hydrolyzed by colonic bacteria to the active metabolite rheinanthrone. Rheinanthrone stimulates peristalsis by acting on the enteric nervous system, increasing colonic motility and fluid secretion via inhibition of Na+/K+ ATPase and activation of prostaglandin pathways. This results in laxation within 6–12 hours. Additionally, emodin and chrysophanol exhibit antimicrobial and anti-inflammatory effects through inhibition of bacterial growth and modulation of NF-κB signaling.
