So named by Juba, in honour of

Euphorbus his physician; schadida-cal/i, tithymalus. aizoides fruticosus, etc. The euphorbium plant. burn, thorny plant, spurge. Euphorbia officinarum Lin. Sp. Pi. 647. It is a prickly lactescent shrub; from which the gummy, resinous, concrete juice, called gum euphorbium, exudes. It is brought from Barbary in drops, or tears, of an irregular form, some of which, when broken, contain little twigs, and other vegetable substances. The tears are brittle; of a gold colour outwardly, and white within: they consist of equal parts of resin and gum; but their acrimony resides in the resin.

The spirituous tinctures are very pungent, and when inspissated more so. The watery infusion and extract are bitterish, with a slight, though durable, acrimony. Neither spirit nor water carries over any portion of this gum in distillation.

Euphorbium is too acrid for internal use; but is an ingredient in some stimulating plasters used in palsies and other disorders. The two compositions of this kind are formed in the following manner:

Emplastrijm euphorbii. Euphorbia 3730 picis burgundicae iv.

euphorbii 3ss. terebinthinae vulgaris q. s. pici burgundies liquefactae adjiciantur euphorbium bene in pulverem redactum, et terebinthinae porlio, adeo ut in spissitudinem propriam abeant. This is a powerful stimulant, well calculated to relieve diseases of the hip joint in their early stage.

Emplastrum ex Euphorbio. Euphorbia 3732 emplastri lithargyri ij. ss. euphorbii bene pulverizati iij. picis burgundicae ss. euphorbium cum olei paululo in mortario teratur, postca, alia, prius liquefacta, adjiciantur. This is highly recommended for promoting the suppuration of sluggish ulcers.

Some have used cuphorbium as an errhinc; but it is too active for this purpose, since in very small quantities it is liable to act with violence; the fine dust which rises in powdering affects the operator's head and throat very powerfully. Cullen's Mat. Medica.

In the 2d vol. of the Medical Museum is an instance, of a person, who, through mistake, swallowed some tincture of euphorbium, and was relieved by frequent draughts of water and olive oil, with a small quantity of camphor. The symptoms produced by the euphorbium were a burning pain in the mouth, throat, and stomach, with a violent suffocation.

Euphorbia parviflora, Lin. Sp. Pi. 653. An Indian herb recommended for syphilis.
