Karaya is the dried exudate of the Sterculia urens Roxburgh plant as well as other types of Sterculia. The trees are wild-growing or cultivated in plantations throughout India and the Sub-Saharan zone. The trees are tapped and the exudate leaks out. A few days later, the still sticky lumps of stems are collected and brought to the villages. The lumps are then air-dried, broken up into nut-sized pieces and cleaned of bark and impurities before they are sorted according to color and purity, and then packaged.
