When one of the familiar sticky berries of the Mistletoe comes into contact with the bark of a tree - generally through the agency of birds - after a few days it sends forth a thread-like root, flattened at the extremity like the proboscis of a fly. This finally pierces the bark and roots itself firmly in the growing wood, from which it has the power of selecting and appropriating to its own use, such juices as are fitted for its sustenance: the wood of Mistletoe has been found to contain twice as much potash, and five times as much phosphoric acid as the wood of the foster tree. Mistletoe is a true parasite, for at no period does it derive nourishment from the soil, or from decayed bark, like some of the fungi do - all its nourishment is obtained from its host. The root becomes woody and thick.

---Description---The stem is yellowish and smooth, freely forked, separating when dead into bone-like joints. The leaves are tongue-shaped, broader towards the end, 1 to 3 inches long, very thick and leathery, of a dull yellow-green colour, arranged in pairs, with very short footstalks. The flowers, small and inconspicuous, are arranged in threes, in close short spikes or clusters in the forks of the branches, and are of two varieties, the male and female occurring on different plants. Neither male nor female flowers have a corolla, the parts of the fructification springing from the yellowish calyx. They open in May. The fruit is a globular, smooth, white berry, ripening in December.

Mistletoe is found throughout Europe, and in this country is particularly common in Herefordshire and Worcestershire. In Scotland it is almost unknown.

The genus Viscum has thirty or more species. In South Africa there are several, one with very minute leaves, a feature common to many herbs growing in that excessively dry climate; one in Australia is densely woolly, from a similar cause. Several members of the family are not parasitic at all,being shrubs and trees, showing that the parasitic habit is an acquired one, and now, of course, hereditary.

Mistletoe is always produced by seed and cannot be cultivated in the earth like other plants, hence the ancients considered it to be an excrescence of the tree. By rubbing the berries on the smooth bark of the underside of the branches of trees till they adhere, or inserting them in clefts made for the purpose, it is possible to grow Mistletoe quite successfully, if desired.

The thrush is the great disseminator of the Mistletoe, devouring the berries eagerly, from which the Missel Thrush is said by some to derive its name. The stems and foliage have been given to sheep in winter, when fodder was scarce, and they are said to eat it with relish.

In Brittany, where the Mistletoe grows so abundantly, the plant is called Herbe de la Croix, because, according to an old legend, the Cross was made from its wood, on account of which it was degraded to be a parasite.

The English name is said to be derived from the Anglo-Saxon Misteltan, tan signifying twig, and mistel from mist, which in old Dutch meant birdlime; thus, according to Professor Skeat, Mistletoe means 'birdlime twig,' a reference to the fact that the berries have been used for making birdlime. Dr. Prior, however derives the word from tan, a twig, and mistl, meaning different, from its being unlike the tree it grows on. In the fourteenth century it was termed 'Mystyldene' and also Lignum crucis, an allusion to the legend just mentioned. The Latin name of the genus, Viscum, signifying sticky, was assigned to it from the glutinous juice of its berries.

---History---Mistletoe was held in great reverence by the Druids. They went forth clad in white robes to search for the sacred plant, and when it was discovered, one of the Druids ascended the tree and gathered it with great ceremony, separating it from the Oak with a golden knife. The Mistletoe was always cut at a particular age of the moon, at the beginning of the year, and it was only sought for when the Druids declared they had visions directing them to seek it. When a great length of time elapsed without this happening, or if the Mistletoe chanced to fall to the ground, it was considered as an omen that some misfortune would befall the nation. The Druids held that the Mistletoe protected its possessor from all evil, and that the oaks on which it was seen growing were to be respected because of the wonderful cures which the priests were able to effect with it. They sent round their attendant youth with branches of the Mistletoe to announce the entrance of the new year. It is probable that the custom of including it in the decoration of our homes at Christmas, giving it a special place of honour, is a survival of this old custom.

The curious basket of garland with which 'Jack-in-the-Green' is even now occasionally invested on May-day is said to be a relic of a similar garb assumed by the Druids for the ceremony of the Mistletoe. When they had found it they danced round the oak to the tune of 'Hey derry down, down, down derry!' which literally signified, 'In a circle move we round the oak. ' Some oakwoods in Herefordshire are still called 'the derry'; and the following line from Ovid refers to the Druids' songs beneath the oak:

'---Ad viscum Druidce cantare solebant---.'

Shakespeare calls it 'the baleful Mistletoe,' an allusion to the Scandinavian legend that Balder, the god of Peace, was slain with an arrow made of Mistletoe. He was restored to life at the request of the other gods and goddesses, and Mistletoe was afterwards given into the keeping of the goddess of Love, and it was ordained that everyone who passed under it should receive a kiss, to show that the branch had become an emblem of love, and not of hate.

---Parts Used Medicinally---The leaves and young twigs, collected just before the berries form, and dried in the same manner as described for Holly.

---Constituents---Mistletoe contains mucilage, sugar, a fixed oil, resin, an odorous principle, some tannin and various salts. The active part of the plant is the resin, Viscin, which by fermentation becomes a yellowish, sticky, resinous mass, which can be used with success as a birdlime.

The preparations ordinarily used are a fluid extract and the powdered leaves. A homoeopathic tincture is prepared with spirit from equal quantities of the leaves and ripe berries, but is difficult of manufacture, owing to the viscidity of the sap.

---Medicinal Action and Uses---Nervine, antispasmodic, tonic and narcotic. Has a greatreputation for curing the 'falling sickness' epilepsy - and other convulsive nervous disorders. It has also been employed in checking internal haemorrhage.

The physiological effect of the plant is to lessen and temporarily benumb such nervous action as is reflected to distant organs of the body from some central organ which is the actual seat of trouble. In this way the spasms of epilepsy and of other convulsive distempers are allayed. Large doses of the plant, or of its berries, would, on the contrary, aggravate these convulsive disorders. Young children have been attacked with convulsions after eating freely of the berries.

In a French work on domestic remedies, 1682, Mistletoe (gui de chêne) was considered of great curative power in epilepsy. Sir John Colbatch published in 1720 a pamphlet on The Treatment of Epilepsy by Mistletoe, regarding it as a specific for this disease. He procured the parasite from the Lime trees at Hampton Court, and recommended the powdered leaves, as much as would lie on a sixpence, to be given in Black Cherry water every morning. He was followed in this treatment by others who have testified to its efficacy as a tonic in nervous disorders, considering it the specific herb for St. Vitus's Dance. It has been employed in convulsions delirium, hysteria, neuralgia, nervous debility, urinary disorders, heart disease, and many other complaints arising from a weakened and disordered state of the nervous system.

Ray also greatly extolled Mistletoe as a specific in epilepsy, and useful in apoplexy and giddiness. The older writers recommended it for sterility.

The tincture has been recommended as a heart tonic in typhoid fever in place of Foxglove. It lessens reflex irritability and strengthens the heart's beat, whilst raising the frequency of a slow pulse.

Besides the dried leaves being given powdered, or as an infusion, or made into a tincture with spirits of wine, a decoction may be made by boiling 2 OZ. of the bruised green plant with 1/2 pint of water, giving 1 tablespoonful for a dose several times a day. Ten to 60 grains of the powder may be taken as a dose, and homoeopathists give 5 to 10 drops of the tincture, with 1 or 2 tablespoonsful of cold water. Mistletoe is also given, combined with Valerian Root and Vervain, for all kinds of nervous complaints, cayenne pods being added in cases of debility of the digestive organs.

Fluid extract: dose, 1/4 to 1 drachm.

Country people use the berries to cure severe stitches in the side. The birdlime of the berries is also employed by them as an application to ulcers and sores.

It is stated that in Sweden, persons afflicted with epilepsy carry about with them a knife having a handle of Oak Mistletoe to ward off attacks.
