This extraction method, otherwise known as tea, is used for the harder parts of dried plants such as roots, rhizomes, bark, and berries.
Simmer the plant in water over low heat for 30-40 minutes, or longer for a stronger tea.
Guideline for amount of herbals for infusion or decoctions:
Typically use more if it is fresh, 1-2 Tablespoons per cup of water
For dried, use 1-2 teaspoons per cup of water
More or less adjusted for taste and desired strength
