Botanical Name: Taraxacum officinale (WEBER)
Family: N.O. Compositae

Description:
It is hardy perennial herb and a tasty salad vegetable.It is very common plant which grows wild almost everywhere.

The Dandelion , though not occurring in the Southern Hemisphere, is at home in all parts of the north temperate zone, in pastures, meadows and on waste ground, and is so plentiful that farmers everywhere find it a troublesome weed, for though its flowers are more conspicuous in the earlier months of the summer, it may be found in bloom, and consequently also prolifically dispersing its seeds, almost throughout the year.
From its thick tap root, dark brown, almost black on the outside though white and milky within, the long jagged leaves rise directly, radiating from it to form a rosette Iying close upon the ground, each leaf being grooved and constructed so that all the rain falling on it is conducted straight to the centre of the rosette and thus to the root which is, therefore, always kept well watered. The maximum amount of water is in this manner directed towards the proper region for utilization by the root, which but for this arrangement would not obtain sufficient moisture, the leaves being spread too close to the ground for the water to penetrate.

The leaves are shiny and without hairs, the margin of each leaf cut into great jagged teeth, either upright or pointing somewhat backwards, and these teeth are themselves cut here and there into lesser teeth. It is this somewhat fanciful resemblance to the canine teeth of a lion that (it is generally assumed) gives the plant its most familiar name of Dandelion, which is a corruption of the French Dent de Lion, an equivalent of this name being found not only in its former specific Latin name Dens leonis and in the Greek name for the genus to which Linnaeus assigned it, Leontodon, but also in nearly all the languages of Europe.

There is some doubt, however, as to whether it was really the shape of the leaves that provided the original notion, as there is really no similarity between them, but the leaves may perhaps be said to resemble the angular jaw of a lion fully supplied with teeth. Some authorities have suggested that the yellow flowers might be compared to the golden teeth of the heraldic lion, while others say that the whiteness of the root is the feature which provides the resemblance. FlÃ¼ckiger and Hanbury in Pharmacographia, say that the name was conferred by Wilhelm, a surgeon, who was so much impressed by the virtues of the plant that he likened it to Dens leonis. In the Ortus Sanitatis, 1485, under ‘Dens Leonis,’ there is a monograph of half a page (unaccompanied by any illustration) which concludes:
‘The Herb was much employed by Master Wilhelmus, a surgeon, who on account of its virtues, likened it to “eynem lewen zan, genannt zu latin Dens leonis” (a lion’s tooth, called in Latin Dens leonis).’
In the pictures of the old herbals, for instance, the one in Brunfels’ Contrafayt Kreuterbuch, 1532, the leaves very much resemble a lion’s tooth. The root is not illustrated at all in the old herbals, as only the herb was used at that time.
The name of the genus, Taraxacum, is derived from the Greek taraxos (disorder), and akos (remedy), on account of the curative action of the plant. A possible alternative derivation of Taraxacum is suggested in The Treasury of Botany:
‘The generic name is possibly derived from the Greek taraxo and achos (pain), in allusion to the medicinal effects of the plant.’
There are many varieties of Dandelion leaves; some are deeply cut into segments, in others the segments or lobes form a much less conspicuous feature, and are sometimes almost entire.
The shining, purplish flower-stalks rise straight from the root, are leafless, smooth and hollow and bear single heads of flowers. On picking the flowers, a bitter, milky juice exudes from the broken edges of the stem, which is present throughout the plant, and which when it comes into contact with the hand, turns to a brown stain that is rather difficult to remove.

Each bloom is made up of numerous strapshaped florets of a bright golden yellow. This strap-shaped corolla is notched at the edge into five teeth, each tooth representing a petal, and lower down is narrowed into a claw-like tube, which rests on the singlechambered ovary containing a single ovule. In this tiny tube is a copious supply of nectar, which more than half fills it, and the presence of which provides the incentive for the visits of many insects, among whom the bee takes first rank. The Dandelion takes an important place among honey-producing plants, as it furnishes considerable quantities of both pollen and nectar in the early spring, when the bees’ harvest from fruit trees is nearly over. It is also important from the beekeeper’s point of view, because not only does it flower most in spring, no matter how cool the weather may be, but a small succession of bloom is also kept up until late autumn, so that it is a source of honey after the main flowers have ceased to bloom, thus delaying the need for feeding the colonies of bees with artificial food.

Many little flies also are to be found visiting the Dandelion to drink the lavishly-supplied nectar. By carefully watching, it has been ascertained that no less than ninety-three different kinds of insects are in the habit of frequenting it. The stigma grows up through the tube formed by the anthers, pushing the pollen before it, and insects smearing themselves with this pollen carry it to the stigmas of other flowers already expanded, thus insuring cross-fertilization. At the base of each flower-head is a ring of narrow, green bracts the involucre. Some of these stand up to support the florets, others hang down to form a barricade against such small insects as might crawl up the stem and injure the bloom without taking a share in its fertilization, as the winged insects do.

The blooms are very sensitive to weather conditions: in fine weather, all the parts are outstretched, but directly rain threatens the whole head closes up at once. It closes against the dews of night, by five o’clock in the evening, being prepared for its night’s sleep, opening again at seven in the morning though as this opening and closing is largely dependent upon the intensity of the light, the time differs somewhat in different latitudes and at different seasons.

When the whole head has matured, all the florets close up again within the green sheathing bracts that lie beneath, and the bloom returns very much to the appearance it had in the bud. Its shape being then somewhat reminiscent of the snout of a pig, it is termed in some districts ‘Swine’s Snout.’ The withered, yellow petals are, however soon pushed off in a bunch, as the seeds, crowned with their tufts of hair, mature, and one day, under the influence of sun and wind the ‘Swine’s Snout’ becomes a large gossamer ball, from its silky whiteness a very noticeable feature. It is made up of myriads of plumed seeds or pappus, ready to be blown off when quite ripe by the slightest breeze, and forms the ‘clock’ of the children, who by blowing at it till all the seeds are released, love to tell themselves the time of day by the number of puffs necessary to disperse every seed. When all the seeds have flown, the receptacle or disc on which they were placed remains bare, white, speckled and surrounded by merely the drooping remnants of the sheathing bracts, and we can see why the plant received another of its popular names, ‘Priest’s Crown,’ common in the Middle Ages, when a priest’s shorn head was a familiar object.

Small birds are very fond of the seeds of the Dandelion and pigs devour the whole plant greedily. Goats will eat it, but sheep and cattle do not care for it, though it is said to increase the milk of cows when eaten by them. Horses refuse to touch this plant, not appreciating its bitter juice. It is valuable food for rabbits and may be given them from April to September forming excellent food in spring and at breeding seasons in particular.

The young leaves of the Dandelion make an agreeable and wholesome addition to spring salads and are often eaten on the Continent, especially in France. The full-grown leaves should not be taken, being too bitter, but the young leaves, especially if blanched, make an excellent salad, either alone or in combination with other plants, lettuce, shallot tops or chives.

Young Dandelion leaves make delicious sandwiches, the tender leaves being laid between slices of bread and butter and sprinkled with salt. The addition of a little lemon-juice and pepper varies the flavour. The leaves should always be torn to pieces, rather than cut, in order to keep the flavour.

John Evelyn, in his Acetana, says: ‘With thie homely salley, Hecate entertained Theseus.’ In Wales, they grate or chop up Dandelion roots, two years old, and mix them with the leaves in salad. The seed of a special broad-leaved variety of Dandelion is sold by seedsmen for cultivation for salad purposes. Dandelion can be blanched in the same way as endive, and is then very delicate in flavour. If covered with an ordinary flower-pot during the winter, the pot being further buried under some rough stable litter, the young leaves sprout when there is a dearth of saladings and prove a welcome change in early spring. Cultivated thus, Dandelion is only pleasantly bitter, and if eaten while the leaves are quite young, the centre rib of the leaf is not at all unpleasant to the taste. When older the rib is tough and not nice to eat. If the flower-buds of plants reserved in a corner of the garden for salad purposes are removed at once and the leaves carefully cut, the plants will last through the whole winter.

The young leaves may also be boiled as a vegetable, spinach fashion, thoroughly drained, sprinkled with pepper and salt, moistened with soup or butter and served very hot. If considered a little too bitter, use half spinach, but the Dandelion must be partly cooked first in this case, as it takes longer than spinach. As a variation, some grated nutmeg or garlic, a teaspoonful of chopped onion or grated lemon peel can be added to the greens when they are cooked. A simple vegetable soup may also be made with Dandelions.

The dried Dandelion leaves are also employed as an ingredient in many digestive or diet drinks and herb beers. Dandelion Beer is a rustic fermented drink common in many parts of the country and made also in Canada. Workmen in the furnaces and potteries of the industrial towns of the Midlands have frequent resource to many of the tonic Herb Beers, finding them cheaper and less intoxicating than ordinary beer, and Dandelion stout ranks as a favourite. An agreeable and wholesome fermented drink is made from Dandelions, Nettles and Yellow Dock.

In Berkshire and Worcestershire, the flowers are used in the preparation of a beverage known as Dandelion Wine. This is made by pouring a gallon of boiling water over a gallon of the flowers. After being well stirred, it is covered with a blanket and allowed to stand for three days, being stirred again at intervals, after which it is strained and the liquor boiled for 30 minutes, with the addition of 3 1/2 lb. of loaf sugar, a little ginger sliced, the rind of 1 orange and 1 lemon sliced. When cold, a little yeast is placed in it on a piece of toast, producing fermentation. It is then covered over and allowed to stand two days until it has ceased ‘working,’ when it is placed in a cask, well bunged down for two months before bottling. This wine is suggestive of sherry slightly flat, and has the deserved reputation of being an excellent tonic, extremely good for the blood.

The roasted roots are largely used to form Dandelion Coffee, being first thoroughly cleaned, then dried by artificial heat, and slightly roasted till they are the tint of coffee, when they are ground ready for use. The roots are taken up in the autumn, being then most fitted for this purpose. The prepared powder is said to be almost indistinguishable from real coffee, and is claimed to be an improvement to inferior coffee, which is often an adulterated product. Of late years, Dandelion Coffee has come more into use in this country, being obtainable at most vegetarian restaurants and stores. Formerly it used occasionally to be given for medicinal purposes, generally mixed with true coffee to give it a better flavour. The ground root was sometimes mixed with chocolate for a similar purpose. Dandelion Coffee is a natural beverage without any of the injurious effects that ordinary tea and coffee have on the nerves and digestive organs. It exercises a stimulating influence over the whole system, helping the liver and kidneys to do their work and keeping the bowels in a healthy condition, so that it offers great advantages to dyspeptics and does not cause wakefulness.

Parts Used Medicinally:-The root, fresh and dried, the young tops. All parts of the plant contain a somewhat bitter, milky juice (latex), but the juice of the root being still more powerful is the part of the plant most used for medicinal purposes.

.
Dandelion root is a registered drug in Canada, sold as a diuretic. Dandelions are so potent in this effect, that children have been known to wet the bed the night after skin contact from playing with them. A leaf decoction can be drunk to “purify the blood”, for the treatment of anemia, jaundice, and also for nervousness.

.The milky latex has been used as a mosquito repellent; the milk is also applied to warts, helping get rid of them without damaging the surrounding skin. A dye can also be obtained from the roots of the plant. A new mixture of roasted roots is sold as a product called DandyBlend which tastes like coffee after the inulin in the dandelion is roasted.

“Dandelion and Burdock” is a soft drink that has long been popular in the United Kingdom with authentic recipes sold by health food shops. It is unclear whether cheaper supermarket versions actually contain either plant.

This plant also is useful in farming, because its deep, strong roots break up hardpan.
