English Oak
Quercus robur
Overview
English oak is a long-lived deciduous tree. In herbal tradition, bark, leaves, and acorns were used.
Oak bark is rich in tannins, which explains its classic astringent, tightening feel.
Traditional uses
- Traditionally used externally as a wash or rinse for minor skin irritation.
- Historically used in folk practice for digestive complaints where an astringent herb was desired.
Preparation
- Decoction (bark, traditional): Simmer 20 g dried bark in 200 ml water for ~30 minutes, then strain. Traditionally used in small, short-term doses.
- Infusion (acorn, traditional): Steep 1 teaspoon ground dried acorn in 200 ml boiled water for ~30 minutes, then strain.
Safety notes
- High-tannin preparations can irritate the stomach and may cause nausea if overdosed.
- Avoid prolonged use. Not for children. During pregnancy: only with medical supervision.
