Description

Valerian is a tall perennial herb with hollow stems that bear white or reddish flowers. Only one stem arises from the root, which attains a height of 3 or 4 feet. It terminates in two or more pairs of flowering stems, each pair being placed at right angles to those above and below it. The lower flowering stems lengthen so as to place their flowers nearly or often quite on a level with the flowers borne by the upper branches, forming a broad and flattened cluster at the summit.

The leaves are arranged in pairs and are united at their bases. Each leaf is made up of a series of lance-shaped segments, more or less opposite to one another on each side of the leaf. The leaflets vary very much in number, from 6-10 pairs as a rule, and vary also in breadth, being broad when few in number and narrower when more numerous; they are usually 2-3 in long. The leaves on the stem are attached by short, broad sheaths, the radical leaves are larger and long-stemmed and the margins more toothed. These plant parts possess an unpleasant aroma due to the contained volatile oils.

Chemical CompositionThe root contains 0.5% - 2% volatile oil, and the oil contains Bornyl isovalerate and bornyl acetate. In addition, it contains some alkaloids such as valerine, chatine, and valepotriatium.
