Blue turmeric, scientifically known as Curcuma caesia, is a rare rhizome native to India and Southeast Asia. Distinguished by its dark blue interior, it possesses a unique camphor-like aroma and earthy flavour. Traditionally used in Ayurvedic medicine for its anti-inflammatory and analgesic properties, blue turmeric is also valued in culinary applications and natural dyes. Its striking colour and potent compounds make it a notable variant among turmeric species.
