Decoctions are made by simmering roots, bark, twigs, and berries in boiling water to extract their medicinal properties. Delicate plant parts like leaves and flowers can be added after the heat is turned off.
HOW TO MAKE A DECOCTION
To make a decoction, simmer herbs in water for 20-30 minutes, strain the liquid, and store in a cool place. A standard quantity is 20g dried or 40g fresh herb to 3 cups of water, reduced to 2 cups after simmering.
The standard dosage is 3-4 doses (2 cups/500ml) each day, and you should store the decoction in a covered jug in the refrigerator or a cool place for up to 48 hours.
