🌱 Introduction: What is Kalonji?
Kalonji, also known as Nigella sativa, is a small black seed packed with immense medicinal power. Often mistakenly referred to as onion seeds, Kalonji belongs to the Ranunculaceae (buttercup) family — not the onion family. These tiny black seeds have been used for thousands of years in traditional medicine systems like Ayurveda, Unani, and Siddha. In English, Kalonji is also called black cumin or fennel flower seeds, though it is botanically different from regular cumin.
