When you want to use the woodier parts of a plant, such as its bark, roots (except Valerian root), bark, and nuts, make a decoction as instructed below. A standard decoction is 1 teaspoon dried herb or 2 teaspoons fresh herb to 6fl oz (175ml) boiling water. If possible, use a steel cast iron pan because aluminum could taint the decoction.
- 1⁄2oz (15g) dried herb or mixture of herbs, or 1oz (30g) fresh herbs,
- 1¼ pints (750ml) cold water.
- Put the chopped herbs in a saucepan, and pour in the water.
- Cover the pan with a lid and bring to a boil, then simmer for 15–20 minutes.
- Strain the decoction and make three doses for use that day.
