Black Turmeric / Karu Manjal
- Black turmeric is a rare herb. It is the underground portion of the stem, or rhizome, of the Cucurma caesia plant.
- The plant itself is sometimes grown as an ornamental, but the root has been used for centuries for medicinal and religious purposes.
- Black turmeric looks quite different than the more common orange turmeric. Black turmeric has an appearance that more closely resembles its cousin, the knobby ginger.
