Quercus robur Fagaceae
Venerated by the Druids the oak was well known for its medicinal powers in the ancient world. The long-lived tree can grow to over 50m tall, with boughs spreading to a circumference of nearly 100m. In spring, dense clusters of oval lobed leaves appear along with dangling male flowers, or catkins. Female .flowers are barely visible, turning to the familiar brown, egg-shaped fruits, or acorns, by autumn.
Tannins make up about 10 to 20 per cent of oak bark. These include epicatechin, gallocatechin and catechin. The highest concentration of tannins is found in trees that are about 10 years old.
Oak bark is known for its ability to combat various viruses, and the tannins give it astringent properties. For these reasons, when taken internally in small doses, it can help to relieve non-specific, acute diarrhoea and indigestion.
Applied externally, it can treat inflamed or chapped skin, chilblains, wet eczema and minor bleeding.It can also be added to baths to combat foot odour.Gargles and mouthwashes made with oak bark are used to soothe inflammation of the gums and lining of the mouth, as well as sore throats.
Tests have recently shown that the tannins in oak are able to limit tissue damage in people suffering from rheumatic disease. This discovery may herald a new medicinal use for the bark of the oak.
Plant acorns in well-drained soil in sun or partial shade, or propagate by grafting in autumn or late winter.
