Introduction—The Healing Power of Keerai
In every Tamil kitchen I grew up in, there was one thing you could always find—a pot of steaming keerai masiyal bubbling on the stove. My grandmother used to say, “Keerai saapidra naal la doctor vendam”—if you eat greens daily, you won’t need a doctor.
And now, science agrees. These humble greens, or keerai as we call them, are packed with nutrients that modern supplements can’t quite match—natural iron, calcium, vitamins, antioxidants, and fiber.
In this article, I’m sharing the five most powerful and time-tested keerai varieties for overall health and wellness—along with their nutritional values, scientific backing, and a few traditional tips from my own kitchen.
