🌿 Ingredients
Modern pharmacological research validates Senna's powerful medical applications, primarily due to its active biochemical constituents:
Bioactive Compound
Chemical Class
Modern Biomedical Function
Sennosides (A, B, C, D)
Anthraquinone Glycosides
• Stimulant Laxative: Triggers rhythmic contractions (peristalsis) in the colon walls, ensuring reliable and efficient bowel evacuation. • Colonic Transit Regulation: Softens stool consistency by stimulating fluid secretion into the large intestine.
Flavonoids & Polysaccharides
Polyphenols
• Antioxidant & Anti-inflammatory: Neutralizes free radicals and mitigates oxidative stress in the gastrointestinal tract.
Mucilage
Complex Carbohydrates
• Protective Coating: Balances the harshness of anthraquinones by soothing the intestinal lining.
⚗️ Preparation Method
Classical & Traditional Preparation Methods
Senna Infusion (Chai / Decoction):
Method: Steep 1 teaspoon of dried Senna leaves (Sana Makki) in hot water for 5 to 10 minutes, then strain. (Often brewed with a pinch of ginger, mint, or aniseed to prevent cramping).
Application: Used traditionally as an occasional deep cleanse for stubborn constipation and toxic accumulation.
Compound Formulation with Honey (Ma'jun):
Method: Blending fine Senna powder with pure honey or natural carminatives.
Application: Consumed in controlled micro-doses to gently purge excess humors and clear cerebral/nervous system blockages.
