What Is a Decoction?

Decoction is a method of extraction by boiling herbal or plant material to dissolve the chemicals of the material, which may include stems, roots, bark and rhizomes.

How do you make a decoction?

Preparing a Decoction
  1. Bring water to boil in a heavy pot.
  2. Measure herbs. Use approximately 1 teaspoon of dried (or 2 teaspoons of fresh) herbs per 1 cup of water.
  3. Add the herbs to the water and reduce heat so that the water is simmering.
  4. Leave the herbs to simmer gently for 15 to 20 minutes.
  5. Strain out the herbs.

What is the difference between an infusion and a decoction?

The difference between infusions (i.e. teas) and decoctions is simple: infusions are steeped and decoctions are simmered.
