From an article by Susun S. Weed.
An infusion is a large amount of herb brewed for a long time. Typically, one ounce by weight (about a cup by volume) of dried herb is placed in a quart jar which is then filled to the top with boiling water, tightly lidded and allowed to steep for 4-10 hours. After straining, a cup or more is consumed, and the remainder chilled to slow spoilage. Drinking 2-4 cups a day is usual. Since the minerals and other phytochemicals in nourishing herbs are made more accessible by drying, dried herbs are considered best for infusions.
I make my infusions at night before I go to bed and they are ready in the morning. I put my herb in my jar and my water in the pot, and the pot on the fire, then brush my teeth (or sweep the floor) until the kettle whistles. I pour the boiling water up to the rim of the jar, screw on a tight lid, turn off the stove and the light, and go to bed. In the morning, I strain the plant material out, squeezing it well, and drink the liquid. I prefer it iced, unless the morning is frosty. I drink the quart of infusion within 36 hours or until it spoils. Then I use it to water my house plants, or pour it over my hair after washing as a final rinse which can be left on.
My favorite herbs for infusion are nettle, oatstraw, red clover, and comfrey leaf, but only one at a time. The tannins in red clover and comfrey make me pucker my lips, so I add a little mint, or bergamot, when I infuse them, just enough to flavor the brew slightly. A little salt in your infusion may make it taste better than honey will.
