Saffron, also known as "kesar" in India, is a popular spice derived from the Crocus sativus flower. Revered for its distinct scent, aroma, and flavour, it is used in various dishes and traditional medicine. Rich in active plant compounds like crocin, crocetin, and safranal, saffron is recognized globally as the "golden spice" for its vibrant colour and health benefits, including potential immunity-boosting properties due to its antioxidant and anti-inflammatory effects.
