Place 3 tablespoons of dried herbs into a small sauce pan.

Cover the herbs with a quart of cold water.

Slowly heat the water to a simmer and cover.

Allow to gently simmer for 20 to 45 minutes.

Strain into a quart jar, but do not discard the herbs. Some water will have evaporated, so your strained liquid will not fill the jar.

Pour additional hot (but not boiling) water over the herbs in the strainer until your jar is full.

Once your decoction is finished simmering, you can infuse more delicate leafy herbs or flowers into the hot water that cannot stand up to the lengthy simmer time, straining the mixture again after another 10 to 15 minutes.
