History
The word Valerian occurs in the recipes of the Anglo Saxon leeches (eleventh century). Valerian, Amantilla and Fu are used as synonymous in the Alphita, a mediaeval vocabulary of the important medical school of Salernum.The derivation of the name of this genus of plants is differently given. It is said by some authors to have been named after Valerius, who first used it in medicine; while others derive the name from the Latin word valere (to be in health), on account of its medicinal qualities.Theriacaria, Marinella, Genicularis and Terdina are other old names by which Valerian has been known in former days. Another old name met with in Chaucer and other old writers is 'Setwall' or 'Setewale,' the derivation of which is uncertain. Mediaeval herbalists also called the plant 'Capon's Tail,' which has rather fantastically been explained as a reference to its spreading head of whitish flowers. The plant was in such esteem in mediaeval times as a remedy, that it received the name of All Heal, which is still given it in some parts of the country. Valerian extracts became popular in the United States and Europe in the mid-1800s, and continued to be used by both physicians and the lay public until it was widely replaced by prescription sedative drugs.
Description
Valerian is a perennial plant, about 2-4 feet high. The yellow-brown, tuberous rootstock produces a hollow, angular, furrowed stem with slender. Horizontal branches which terminate in buds are given off earlier, and from these buds proceed aerial shoots or stolons, which produce fresh plants where they take root. 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, called a cyme.The limb of the calyx is remarkable for being at first inrolled and afterwards expanding in the form of a feathery pappus, which aids the dissemination of the fruit. 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 (pinnate). The leaflets vary very much in number, from six to ten pairs as a rule, and vary also in breadth, being broad when few in number and narrower when more numerous; they are usually 2 to 3 inches long. The margins are indented by a few coarsely-cut teeth. The upper surface is strongly veined, the under surface is paler and frequently more or less covered with short, soft hairs. The leaves on the stem are attached by short, broad sheaths, the radical leaves are larger and long-stemmed and the margins more toothed. The fruit is a capsule containing one oblong compressed seed. Apart from the flowers, the whole plant has a foetid smell, much accentuated when bruised.Range
The plant is found throughout Europe and Northern Asia, and is common in England Two species of Valerian, Valeriana officinalis and V. dioica, are indigenous in Britain, while a third, V. pyrenaica, is naturalized in some parts. The genus comprises about 150 species, which are widely distributed in the temperate parts of the world.Habitat
This herb thrives best in marshy thickets and on the borders of ditches and rivers. valerian grows wild in damp conditions. Valerian does well in all ordinary soils, but prefers rich, heavy loam, well supplied with moisture.Cultivation
The wild plants are collected from local woods and transplanted to the prepared land. Generally the young flowering plants given off by the perennial rhizomes of old plants which develop towards the close of summer are given preference. These should be set 1 foot apart in rows, 2 or 3 feet apart. The soil should first be treated with farmyard manure, and after planting it is well to give liquid manure from time to time, as well as plenty of water. The soil must be well manured to secure a good crop. Weeding requires considerable attention.Propagation may also be by seed, either sown when ripe in cold frames, or in March in gentle heat, or in the open in April. In the first two cases, transplant in May to permanent quarters. But to ensure the best alkaloidal percentage, it is best to transplant and cultivate the daughter plants of the wild Valerian. The flowering tops must be cut off as they appear, thus enabling the better development of the rhizome. Many of the young plants do not flower in the first year, but produce a luxuriant crop of leaves, and yield rhizome of good quality in the autumn.
