What is Black Turmeric and its uses

Black turmeric (Curcuma caesia) also known as Black zedoary or Kali haldi is a perennial herb with bluish-purple rhizome. Found in the North East India and Madya Pradesh regions, it is a powerful, medicinal plant with some amazing health benefits. Usually sold in fresh and dried forms, unfortunately it is still a rare and expensive root. Good news though – if you live in a warm climate or have the right conditions, you can grow your own, and if you feel too lazy for that, you can always order Turmeric Supreme Extra Strength. In this article we will discuss the benefits of this less-known plant, so let’s dive in into its amazing health benefits.



Health benefits of black turmeric

Curcuma caesia is related to both ginger and yellow turmeric. Although still lacking in thorough research, initial animal studies have shown promising health benefits, some of which include:

Anti-inflammatory properties

Black turmeric, just like yellow turmeric, has antioxidant and anti-inflammatory properties. It may help improve arthritis, muscle and joint pain, lower inflammation in the gut and provide better digestion. It is usually used in dried form, added to various dishes or in fresh form, added to tea or blended into smoothies.


This bluish-purple plant contains the highest concentration of curcumin. Curcumin is known for its healing and antifungal properties. Curcumin is the bright yellow chemical compound found in many species of the ginger family. It is advised to mix curcumin with black pepper in order to improve its bio-availability.

Muscle relaxant

Turmeric also shows promising results in being a natural anticonvulsant and muscle relaxant. It may reduce the severity of epileptic fits and help induce muscle relaxation.

Analgesic properties

Extracts from both yellow and black turmeric possess analgesic properties and can help reduce both acute and chronic pain especially muscle and joint pain. It can help reduce the severity of arthritis, as well as help reduce the pain induced by sore muscles.

Anti-bacterial properties

Turmeric is also a great antibacterial plant that can help reduce the number of “bad” bacteria in the body, especially in the gut, therefore it can improve digestion and reduce bloating.

Anti-asthmatic activity

Black zedoary may provide broncho-dilating activity and animal studies showed promising effects in reducing histamine induced bronchospasms.

Immune system

Kali haldi can help improve the functions of the immune system thanks to its antibacterial, antifungal, anti-inflammatory and antioxidant properties. It may help reduce oxidative stress and reduce the effects and duration of both the common cold and seasonal flu.


Taste and medicinal value

The rhizomes of the herb are often used to reduce the effects of cold, fever, muscle spasm, cough and various inflammations throughout the body. Turmeric has a spicy, pungent taste and a sweet smell thanks to the presence of essential oils and over 30 components as well as terpenoids, flavonoids, steroids, and alkaloids as major constituents.



The cultivation process is similar to that of yellow turmeric. Planting takes place around June/July and it is advised to water the rhizomes 2-3 times a week in the beginning stages and less in the latter stages. After approximately 8 months the root is ready for harvest. The rhizomes are washed and placed in cauldrons then boiled for around 30 minutes and when the water content is reduced to around one-third of the original amount, they are dried for around 10-15 days, ideally in the hot sun.


Ethnic and cultural uses

Crushed turmeric has long been used as a natural antidote to snake, scorpion and spider bites across India. It is also used in religious rituals such as the sacred ceremony for the Goddess Kali, hence the alternative name Kali haldi. Another fact worth mentioning is that the plant is believed to bring abundance, prosperity and protection. The blue root is also believed to ward off evil spirits and it is commonly carried in pockets or medicine bags.
