Today, it is more or less impossible to find the tree turmeric ( Coscinium fenestratum ) — popular as Mara Manjal in Malayalam and Tamil — in its natural habitat, as 80% of the population has vanished, according to KAU scientists. After years of study and careful research, they have cultivated saplings that are now on sale on the main campus at Vellanikkara, Thrissur.
The plant, the export of which is banned, is ideal for gardens, homesteads, and plantations, said B. Suma, professor and head, KAU Cocoa Research Centre, who has been associated with the tree turmeric project at the KAU since 2013.

“It was once abundant in the Western Ghat regions and parts of Karnataka. Outside India, it is found in places such as Sri Lanka and Vietnam. The DST-funded project at the Plantation Crops and Spices Department at the KAU was launched in 2013 as a conservation measure,” Dr. Suma said. Known as Daruharidra in Sanskrit, tree turmeric is valued for its antiseptic properties.
It is a prime ingredient in Ayurvedic preparations, including Aswagandharishtam, Khadirarishtam, Mahapanchagavyam, and Ilaneer Kuzhambu.
Characterised by sluggish initial growth, its natural propagation has been hindered in recent times, pushing it gradually to the brink of extinction in this part of the world.

“Once it gains leaves, the growth speeds up. A woody perennial, it can be grown on trees,” Dr. Suma said.
The KAU has 1,000 saplings for sale at ₹500 each. For details, call 0487 2438451.
