Oak

Oak (Quercus robur Fagaceae)


Other Names: Common Oak, Pedunculate Oak, English Oak

Oak, revered by the Druids for its healing properties, is a long-lived tree that can grow over 50 meters with a canopy up to 100 meters in circumference. In spring, it produces dense oval leaves and male flowers in fringes, while female flowers yield brown acorns in autumn.


Parts for Use

Bark of Young Branches

  1. Bark is harvested in April and May, then cut or crushed for use.
  2. Used in decoctions, tinctures, compresses, and added to hand or foot baths.
  3. Often combined with astringent plants like blueberries, cranberries, and witch hazel.

Ingredients

Oak bark contains 10–20% tannins, including epicatechin, gallocatechin, and catechin, with the highest concentration in trees around 10 years old.


Use in Treatment

Oak bark’s tannins provide astringent and antiviral properties, effective for acute diarrhea and indigestion. Externally, it treats inflamed or cracked skin, frostbite, wet eczema, minor bleeding, and unpleasant foot odor. Gargling or mouthwashes with oak bark soothe gum inflammation, oral cavity issues, and sore throats. Recent studies suggest tannins may limit tissue damage in rheumatism, opening new treatment possibilities.


Cultivation

Oak is grown from acorns planted in well-drained soil in a sunny or semi-shady spot or propagated by layering in autumn or late winter.

For Internal Use (Acute Diarrhea)

  1. Infusion: Steep 10 grams of bark powder in a cup of boiling water, drink 4–5 cups daily.

For External Use (Foot Odor, Inflamed or Cracked Skin, Frostbite, Wet Eczema, Minor Bleeding)
