Herbal medicines may be presented in many forms including fresh, dried, whole, or chopped. Herbs may be prepared as infusions when an herb is soaked in a liquid or decocted—simmered in water over low heat for a certain period. Some examples of infusion are chamomile or peppermint, using flowers, leaves and powdered herbs. Decocting examples may be rose hips, cinnamon bark, and licorice root consisting of fruits, seeds, barks, and roots. Fresh and dried herbs can be tinctured where herbs are kept in alcohol or contained in a vinegar extract. They can be preserved as syrups such as glycerites in vegetable glycerin or put in honey known as miels. Powdered and freeze dried herbs can be found in bulk, tablets, troches similar to a lozenge, pastes, and capsules.
