How should a decoction of LEKRASET oak bark be prepared for rinsing or compresses?

Oak bark is a plant material used to make infusions or decoctions by steeping. The general principle: the material is covered with hot water, left for a certain time, then strained and used once cooled to a comfortable temperature.

For rinsing the mouth, a small amount of material per glass of water is usually taken; the longer it infuses, the more pronounced the astringent effect will be. It is best to start with a less concentrated infusion to see how the mucous membranes react.

For compresses and local baths, the concentration can be increased slightly, but the principle is the same: the finished decoction is strained, cooled and used locally on the area in question. A compress is applied for a few minutes, and a bath is kept short.

A few practical points:

• The finished decoction should not be kept for long: it is best to make a fresh one for each use or to use it within 24 hours, keeping it in the fridge.
• Choose enamelled or glass containers: the bark contains tannins, which can react with metal.
• If your skin or mucous membranes are sensitive, test the reaction on a small area the first time.

If you have any doubts about the method of use or the concentration, consult a specialist before you start.
