The insects live inside these galls, obtaining their nutrient therein. When the insect pupates and leaves, the gall can be used as a rich source of tannin, that can also be used as a dyestuff. The branches have been used to make rims for twined work baskets. The acorn meal has been used to mend cracks in clay pots. The seed cups are used as buttons.Wood - hard, heavy, strong, brittle.
