Decoctions

A decoction is the preferred method used for hard and woody plant material such as, bark, stems, roots, rhizomes, and seeds.

First, grind the dried plant material into a powdered state. If using fresh plant material, cut into small pieces or macerate (crush) them. Use 1 teaspoon dried or 1 tablespoon fresh herb per 1 cup (250mL) water. Always start with cold water, as this allows the plant constituents to be extracted before the coagulation of other plant constituents, e.g. protein, occurs which blocks the extraction of these substances. Bring the mixture to a boil over medium heat, then reduce, cover, and simmer for 15 to 20 minutes or until water is reduced by half. Strain while hot and use as you would an infusion.

When preparing a remedy using both soft and woody herbs, it is best to prepare the infusion and decoction separately before combining, for the most effective extraction.

If using herbs with a high percentage of volatile oils, it is best to powder the herbs finely and use an infusion technique.

Adult Dosage: 1 cup (250mL) three times daily. Larger quantities can be made and stored as for infusions.
