An extract is a substance made by isolating the essence of herb into alcohol or other solvent and then removing and discarding the solid parts. Alcohol extracts a greater amount of medicinal properties than just water or glycerine. Many herbs are very resinous which makes them not water soluble and are only able to extract into alcohol.
The aromatic principles of many spices, nuts, herbs, fruits, etc., and some flowers, are marketed as extracts, among the best known of true extracts being almond, cinnamon, cloves, ginger, lemon, nutmeg, orange, peppermint, pistachio, rose, spearmint, vanilla, violet, and wintergreen.

A majority of other, concentrated fruit flavors, such as banana, cherry, currant, peach, pineapple, raspberry and strawberry, are produced by combinations of various esters, together with special oils.
Single herbs may be used to produce an herbal extract while multiple herbs with properties benefiting specific conditions are sometimes combined in the same extraction process to make a tincture. A more exacting method is to extract individual herbs then combine the extracts in precise proportions.
