Chemical Composition

• Other components include flavonoids, tannins, and mucilage.
• Sennosides: The primary active compounds, sennosides, stimulate peristalsis in the intestines by irritating the bowel lining.

Pharmacology and Mechanism of Action

• Laxative Effect: Senna acts as a stimulant laxative.
• The sennosides are metabolized by intestinal bacteria into active forms that irritate the bowel mucosa, leading to increased peristalsis and bowel movement.
• Diuretic Effect: It has mild diuretic properties due to its impact on renal function, affecting urine output and specific gravity.
• Anti-inflammatory and Antiseptic: The plant may also have mild anti-inflammatory and antiseptic effects due to its flavonoid content.

Medical Uses

• Digestive Disorders: It can be used in cases of flatulence, dyspepsia, and digestive sluggishness.
• Liver Disorders: Senna can assist in detoxifying the liver and alleviating symptoms of liver congestion.

DRUG PATHOGENESIS

• Senna works by stimulating the intestines and promoting bowel movements.
• It also increases the specific gravity of urine due to its effects on the kidneys, making it useful in cases of oxaluria and hyperazoturia.
• It is particularly effective when the body is weakened, with increased nitrogen waste and a buildup of toxic substances.

KEY CHARACTERISTICS

• Constipation: Hard, dark stools often associated with an enlarged and tender liver, loss of appetite, and coated tongue.
• Flatulence: Colic and flatulence often accompany constipation, indicating the need for Senna.
• Liver Symptoms: The liver may be enlarged and tender, a sign of congestion or dysfunction.

URINARY SYSTEM

• Urine Characteristics: Increased specific gravity and density, often seen in cases of oxaluria, hyperazoturia, phosphaturia, and acetonuria.
• Oxaluria: Excess oxalates in the urine, which can lead to kidney stones.
• Acetonemia: High levels of acetone in the blood, leading to fainting and prostration in severe cases.

GENERAL SYMPTOMS

• Muscular Weakness: Loss of muscle strength, especially with digestive and liver issues.
• Prostration and Fainting: Seen in cases of acetonemia or when the system is breaking down from excess waste material.

• Better: After the passage of stools or gas.

RELATIONSHIP WITH OTHER REMEDIES

• Compare: Kali carb, Jalapa – both are remedies for colic and digestive issues.
