Katri Gum is an exudate of sterculia trees and it is comprised of acid polysaccharide sugars such as galactose, galacturonic acid and rhamnose. In Ayurveda, it holds a special place due to its medicinal properties and has been used to cure various diseases like cough and dysentery. This tasteless and odourless gum changes its texture and appearance just by soaking in water/milk to white jelly from a crystal.
