Used for beneficial properties at the time of Hippocrates in the 4th and 5th centuries B.C., Valerian (Valeriana officinalis) is native to England, Europe and the United States. Valerian derives its name from the Latin valere, "to be strong" referring to both the plant as well as its distinct odor. It was also referred to as "All-Heal" during the Middle Ages in Britain. In centuries past, it was taken for its soothing, beneficial effect, used as a condiment during medieval times and as a perfume during the 16th century. Today, Valerian Root is used throughout Europe and the U.S.
