Bugle, Common

Bugle, Common

There are three Bugles in the British flora - the common creeping form (Ajuga reptans), the erect Bugle (A. pyramidalis), a rare Highland species, and the Yellow Bugle or Ground Pine (A. Chamaepitys), which likewise has its reputation as a curative herb.

Description: It is a perennial, to be found in flower from the end of April to the beginning of July and well marked by its solitary, tapering flower-stalks, 6 to 9 inches high, and its creeping scions or runners. These are long shoots, sometimes a couple of feet or more long, sent out from the rootstock. At intervals upon them are pairs of leaves, and at the same point rootlets are given off below, which enter the earth. As winter approaches, the runners die, but at every point where the leaf-pairs and the rootlets were formed, there is a dormant plant waiting to develop fully in the spring, a Bugle plant thus being the centre of quite a colony of new young plants, quite independently of setting its seeds, which as a matter of fact do not always ripen, the plant propagating itself more largely by its creeping scions.

The erect flower-stalk sent up from the root-stock is square, pale green, often purplish above, with the leaves opposite in pairs, the lower leaves on stalks, the upper leaves stalkless, oblong and obtuse in form, toothed or almost entire at the margin, having manycelled hairs on both surfaces, the margins also fringed with hairs. The runners are altogether smooth, but the stems are smooth only on two sides and downy on the other two.

The flowers are of a purplish blue, crowded into a spike formed of about six or more rings of whorls, generally six flowers in a whorl. The upper leaves or bracts interspersed between the whorls are also tinged with the same colour, so that ordinarily the whole of the upper portion of the plant has a bluish appearance. A white variety is sometimes found, the upper leaves then being of the normal green colour.

The flowers are adapted by their lipped formation for cross-fertilization by bees, a little honey being found at the base of the long tube of the corolla. The upper lip is very short and the lower three-cleft. The stamens project. The flowers have practically no scent. After fertilization, small blackish seeds are formed, but many of the ovules do not mature.

The rather singular names of this plant - both popular and botanical - are not very easy to account for. It has been suggested that 'Bugle' is derived from bugulus, a thin, glass pipe used in embroidery, the long, thin tube of the corolla being thought to resemble this bead bugle. It is more likely to be a corruption of the Latin name Ajuga, the generic name which Linnaeus was the first to apply to this plant from a belief that this or some closely-allied species was the one referred to by Pliny and other writers by a very similar name, a name probably corrupted from Abija, in turn derived from the Latin word abigo, to drive away, because the plant was thought to drive away various forms of disease. In former days it was held to possess great curative powers. Prior, writing in the seventeenth century, tells us: 'It is put in drinkes for woundes and that is the cause why some doe commonly say that he that hath Bugle and Sanicle will scarce vouchsafe the chirugeon a bugle.' The early writers speak of the plant as the Abija, Ajuga, Abuga and Bugula, and the common English name, Bugle, is clearly a corruption of one or other of these forms.

Part Used Medicinally: The whole herb, gathered in May and early June, when the leaves are at their best, and dried.

Medicinal Action and Uses: Bitter, astringent and aromatic.

In herbal treatment, an infusion of this plant is still considered very useful in arresting haemorrhages and is employed in coughs and spitting of blood in incipient consumption and also in some biliary disorders, a wineglassful of the infusion - made from 1 OZ. of the dried herb to 1 pint of boiling water - being given frequently.

In its action, it rather resembles digitalis, lowering the pulse and lessening its frequency, it allays irritation and cough, and equalizes the circulation and has been termed 'one of the mildest and best narcotics in the world.' It has also been considered good for the bad effects of excessive drinking. Green (Universal Herbal, 1832) gives as his opinion that 'the leaves may be advantageously used in fluxes and disorders of that kind as they do not, like many other plants of the same value, produce costiveness, but rather operate as gentle laxatives.'

He states that a decoction of the herb has been employed for quinsy on the Continent, where the herb has been more employed as a remedy than in this country.

The roots have by some authorities been considered more astringent than the rest of the plant. Culpepper had a great opinion of the value of the Bugle and says, 'if the virtues of it make you fall in love with it (as they will if you be wise) keep a syrup of it to take inwardly, and an ointment and plaster of it to use outwardly, always by you. The decoction of the leaves and flowers in wine dissolveth the congealed blood in those that are bruised inwardly by a fall or otherwise and is very effectual for any inward wounds, thrusts or stabs in the body or bowels; and is an especial help in wound drinks and for those that are liver-grown, as they call it. It is wonderful in curing all ulcers and sores, gangrenes and fistulas, if the leaves, bruised and applied or their juice be used to wash and bathe the place and the same made into lotion and some honey and gum added, cureth the worse sores. Being also taken inwardly or outwardly applied, it helpeth those that have broken any bone or have any member out of joint. An ointment made with the leaves of Bugle, Scabious and Sanicle bruised and boiled in hog's lard until the herbs be dry and then strained into a pot for such occasions as shall require, it is so efficacious for all sorts of hurts in the body that none should be without it.'
