Phytochemical, Pharmacognostic and Pharmacological Evaluation of Madhuca longifolia (Koen.) Flowers for DiureticActivity

Medicinal plants form the backbone of traditional systems of medicine across the world. Diuretics are drugs that increase urine output and are commonly prescribed for hypertension, edema, congestive heart failure and renal disorders. Synthetic diuretics often produce adverse effects such as electrolyte imbalance and dehydration, necessitating safer alternatives. Madhuca longifolia (Mahua) is an important Indian medicinal tree belonging to family Sapotaceae. Flowers of this plant are traditionally used for urinary complaints, inflammation and metabolic disorders.
