Heirloom Rice Varieties: Why Mapillai Samba & Karuppu Kavuni Endure\n\nLong before commercial monoculture popularized high-yielding white rice, farmers across Tamil Nadu nurtured over 200 distinct indigenous paddy landraces.\n\n### Mapillai Samba: The Grain of Strength\nTraditionally gifted to bridegrooms to demonstrate physical stamina, Mapillai Samba is a hardy red rice variety rich in iron and zinc. Its deep root structure allows it to thrive in both severe water stress and river basin floods.\n\n### Karuppu Kavuni: Anthocyanin Powerhouse\nRevered for its purple-black color, Karuppu Kavuni carries anthocyanins that give it potent anti-inflammatory properties. Historically cooked into slow-simmered payasam or savory porridge, it delivers sustained energy throughout the day.
