Korai Kilangu (Cyperus rotundus), or Nut Grass/Purple Nut Sedge, is a fragrant, tuberous, perennial weed known for its medicinal rhizomes. Commonly used in Siddha and Ayurveda, the small, potato-like tubers are dried and used to treat digestive issues, skin ailments (scabies/eczema), fever, and gynecological disorders due to their anti-inflammatory and antiseptic properties.

• Medicinal Properties: Known to reduce fever, manage blood sugar, aid in weight management, and provide pain relief.
• Gynecological Care: Used to improve breast milk secretion and regulate menstrual issues.
