Curcuma caesia, also known as black turmeric, is a plant with various traditional medicinal uses. Its rhizome, the most important part, is used to treat a range of ailments, including asthma, cancer, wounds, allergies, toothache, leprosy, bronchitis, epilepsy, hemorrhoids, leukoderma, and rheumatoid arthritis
The cultivation and harvest practices are similar to that of common turmeric.[3] In the fields, the rhizomes are washed thoroughly and are placed in a wide mouthed cauldron. The water is poured in the cauldron such that the rhizomes are completely covered. The cauldron is covered with a lid, and the rhizomes are boiled for about 30 minutes until foam oozes out with a strong odour. The rhizomes are taken out when the water is reduced to one-third of the original and they are soft and their inner portion has turned from blue to dark or pale brown.
