Oak galls are excrescences that are sometimes produced in great numbers on the tree and are caused by the activity of the larvae of different insects. 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 bark is a commercial source of tannin. Dyes of various colours can be obtained from the bark.Wood - very heavy, hard, strong, tough, close grained but difficult to work. It weighs 59lb per cubic foot. It is used for making hubs, cogs, shipbuilding etc. A very good fuel.
A decoction of the wood chips or the bark has been applied externally as an astringent analgesic to treat aches and pains, sores and haemorrhoids.Any galls produced on the tree are strongly astringent and can be used in the treatment of haemorrhages, chronic diarrhoea, dysentery etc.

The tree flowers on new growth produced in spring, the seed ripening in its first year. Abundant crops are usually produced in the wild. Intolerant of root disturbance, trees should be planted in their permanent positions whilst young. Hybridizes freely with other members of the genus.Plants in this genus are notably resistant to honey fungus.
