The goal of the herbalist is to release the volatile oils, antibiotics, aromatics, and other healing chemicals contained by the herb. Herbs can be prepared in a variety of forms depending on their purpose. Such techniques include:
　　
　　Juice squeezed from herbs.
　　Mashing herbs into a paste.
　　Decoction or extracting the active ingredients by boiling down the herb in water.
　　Hot infusion (like hot tea)- Herb is steeped in hot water.
　　Cold infusion (like sun tea) - Herb is steeped in cold water.
　　Herbs ground into a powder and used as such or as compressed into a pill.
　　Herbal wine made by adding the herb to water and sugar and letting it ferment.
　　Tincture, made by combining ground herbs with alcohol, glycerin or vinegar and used internally.
　　Liniment - Made like a tincture except it is used externally.
　　Salves and ointments made by adding herbs to a medium such as petroleum jelly.
　　Syrups - Made by adding herb to a medium such as honey, sugar or glycerin.
　　Poultice - Herb is applied directly to a wound or body part and held in place with a cloth.
　　Herbal Oil - Usually made with common base oil, such as olive, almond, grape seed, or sesame oils. The herb is allowed to sit in the oil for a week. It is strained and bottled.
　　
　　In general, delicate leaves and flowers are best infused. Boiling may cause them to lose the volatile essential oils. Roots, barks, and seeds are best made into decoctions.
