Herbal Infusions
Infusions are made from the aerial parts of the herb . . the leaves and flowers. Since these are the more fragile parts they must be steeped and not simmered.
To make an infusion, boil 1 cup of water or preferably 1 quart of water and pour over the herb in a cup or quart jar. The tea will become stronger the longer you let it steep. Start with 3-5 minutes and use your taste buds to determine how long to let it steep. Use 2 tablespoons of fresh herb or 1 tablespoon of dried to make 1 cup, and 2 oz of fresh herb or 1 oz dried herb per quart. If you prefer a stronger tea, simply add more of the herb or let it steep longer. (Making tea by the quart simply saves time if you will be drinking the the tea over 2 to 3 days. If you are making a quart of tea, please refrigerate what you will not be drinking right away. If it is left at room temperature it may spoil.)
Herbal Decoctions
Decoctions are made from the roots or bark of the herbs. It is usually more difficult to extract the constituents from these parts, so they require simmering.
To make a decoction, place the herb in a saucepan and cover with cold water using 1 oz of herb per 16 ounces of water. Cover saucepan and slowly bring to a simmer over low heat. Simmer for 20-45 minutes depending upon how strong you like your decoction.
