Barberry, Common | | Name : | Barberry, Common | | Botanical : | Berberis vulgaris | | Synonyms : | Berbery. Pipperidge Bush. Berberis Dumetorum. | | Family : | Berberidaceae | | Parts Used : | Bark, root-bark. | | Habitat : | The Common Barberry, a well-known, bushy shrub, with pale-green deciduous leaves, is found in copses and hedges in some parts of England, though a doubtful native in Scotland and Ireland. It is generally distributed over the greater part of Europe, Northern Africa and temperate Asia. As an ornamental shrub, it is fairly common in gardens. | | Description : | The stems are woody, 8 to 10 feet high, upright and branched, smooth, slightly grooved, brittle, with a white pith and covered with an ash-coloured bark.
The leaves of the barren shoots of the year are alternate, 1 to 1 1/2 inch long, shortly petioled, presenting various gradations from leaves into spines, into which they become transformed in the succeeding year. The primary leaves on the woody shoots are reduced to three-forked spines, with an enlarged base. The secondary leaves are in fascicles from the axil of these spines and are simple, oval, tapering at the base into a short foot-stalk, the margins finely serrate, with the teeth terminating in small spines.
The flowers are small, pale yellow, arranged in pendulous racemes, produced from the fascicles of leaves, towards the ends of the branches. Their scent is not altogether agreeable when near, but by no means offensive at a distance. Their stamens show remarkable sensibility when touched springing and taking a position closely applied to the pistil. Insects of various kinds are exceedingly fond of the Barberry flower. Linnaeus observed that when bees in search of honey touch the filaments, they spring from the petal and strike the anther against the stigma, thereby exploding the pollen. In the original position of the stamens, Iying in the concavity of the petals, they are sheltered from rain, and there remain till some insect unavoidably touches them. As it is chiefly in fine, sunny weather that insects are on the wing, the pollen is also in such weather most fit for the purpose of impregnation, hence this curious contrivance of nature for fertilizing the seeds at the most suitable moment.
The berries are about 1/2 inch long, oblong and slightly curved; when ripe, of a fine, red colour and pleasantly acidulous.
The leaves are also acid, and have sometimes been employed for the same purposes as the fruit. Gerard recommends the leaves 'to season meat with and instead of a salad.'
Cows, sheep and goats are said to eat the shrub, horses and swine to refuse it, and birds, also, seldom touch the fruit, on account of its acidity; in this respect it approaches the tamarind. | | Constituents : | The chief constituent of Barberry bark is Berberine, a yellow crystalline, bitter alkaloid, one of the few that occurs in plants belonging to several different natural orders. Other constituents are oxyacanthine, berbamine, other alkaloidal matter, a little tannin, also wax, resin, fat, albumin, gum and starch. | | Uses : | Tonic, purgative, antiseptic. It is used in the form of a liquid extract, given as decoction, infusion or tincture, but generally a salt of the alkaloid Berberine is preferred.
As a bitter stomachic tonic, it proves an excellent remedy for dyspepsia and functional derangement of the liver, regulating the digestive powers, and if given in larger doses, acting as a mild purgative and removing constipation.
It is used in all cases of jaundice, general debility and biliousness, and for diarrhoea. |
