Valerian is found in mountainous reason in Nepal. It is a perennial herd to 45 cm tall with thick, nodular and aromatic root stock. Basal leaves with ovate-heart shaped acute blade, 2.5-8 cm, and toothed or wavy-margined, long stalked; stem leaves few, small, entire or pinnate lobed. Flowers white or pink tinged, in terminal clusters, borne on erect nearly leafless stem. Fruits are small with persistent papas like calyx. This herb has been highly esteemed since medieval times and used to be call "all heal." The fragrance is rather unpleasant for most people but when mixed with other more pleasant-smelling oils it can be tolerated. It is best used in very small amounts--too much can dull the senses. The oil is produced by steam distillation of the roots of the plant.
