Curcuma caesia, commonly known as Black Turmeric, is a perennial herbaceous plant belonging to the genus Curcuma in the family Zingiberaceae. It is native to Northeast India and is known for its distinctive black rhizomes.

Description

Curcuma caesia is a small, erect plant that typically grows to a height of 1 to 1.5 meters. The plant has large, oblong leaves that are dark green in color with a reddish midrib. The rhizomes are the most distinctive feature of the plant, being dark blue to black in color, and are aromatic with a camphoraceous smell.

Habitat

Curcuma caesia is primarily found in the tropical and subtropical regions of Northeast India, particularly in the states of Assam, West Bengal, Odisha, and Chhattisgarh. It thrives in well-drained, loamy soils and requires a warm and humid climate for optimal growth.

Uses

The rhizomes of Curcuma caesia have been traditionally used in Ayurvedic and Unani systems of medicine. They are believed to possess various medicinal properties, including anti-inflammatory, anti-oxidant, and analgesic effects. The rhizomes are also used in religious rituals and as a natural dye.

Cultivation

Curcuma caesia is propagated through its rhizomes. The planting is usually done at the onset of the monsoon season. The rhizomes are planted in well-prepared soil beds, and the plants require regular watering and care to ensure healthy growth. Harvesting is typically done 8 to 10 months after planting when the leaves start to wither.

Conservation Status

Due to overharvesting and habitat destruction, Curcuma caesia is considered to be at risk in some regions. Efforts are being made to cultivate the plant sustainably and to conserve its natural habitat.
