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 is often used for its soothing, relaxing beneficial properties. Peppermint (Mentha piperita) is a universally-loved and widely-used flavoring. Peppermint's value comes from the mint's volatile oil, which contains menthol, and is added to many formulas for its therapeutic properties. So highly thought of, Peppermint was included in a list of plants being taken to the New World. Together, Valerian and Peppermint make a calming, relaxing tea.
