Historical importance

The Cutch tree is exported from the middle ages from India to China and Japan, then to Europe under the name of “terra japonica.”
The Cutch tree was used for dyeing textile fibbers exposed to weather: fishing nets, boat sails, tarpaulins, tents, and also for leather.


Cutch tree contains 55 to 60% of cutch tannins (hence its name): catechins, epicatechins, gallocatechins, epigallocatechins, etc … it also contains flavonols principally quercetin.

Crop production – Manufacturing

The best yields are obtained with thirty years old Cutch trees. In 1975 the crude production of Cutch t was 5000-6000 tonne/year.
