[164] This substance must not be confounded with BEEBERINE or BIBERINE (which see).

Prep. 1. A soft watery extract of the root, or of the wood, is digested in rectified spirit, with trituration, as long as anything is taken up; the resulting tincture, after repose, is filtered, and the alcohol gradually distilled off until the residuum has the consistence of a thin syrup. The crystals which form as the liquid cools are drained in a funnel, washed with a few drops of ice-cold water, pressed dry in bibulous paper, and then purified by solution and crystallisation, first in rectified spirit, and next in distilled water.

2. By digesting the root, or the wood (coarsely powdered) in rectified spirit, and then proceeding as before.

Prop. Berberine may be classed with the azotised colouring substances; or, from its composition and its possessing feeble basic properties, with the alkaloids. It crystallises in fine needles, or in stellated prisms, which are yellow, odourless, very bitter-tasted, neutral to test-paper, and contain 12 equiv. of water. At 212° Fahr. it acquires a red colour; but recovers its normal yellow on cooling. A much higher temperature decomposes it, yellow vapours being evolved. It is freely soluble in boiling water and in alcohol, from either of which solutions it may be readily obtained in crystals. It requires 500 parts of water at 60° to dissolve it, and very much more at lower temperatures. Its solutions are yellow; that in alcohol appears green by reflected light. The concentrated mineral acids destroy it. Its salts are more or less soluble.

Uses, &c. Chiefly in medicine, in similar cases to those in which the use of calumba-root is indicated. It has been highly recommended in dyspepsia and heartburn, in disturbed action of the liver, and, combined with iron (lactate, phosphate, or hyposulphite), in chlorosis, anæmia, &c. According to M. Altin, it is an effectual remedy for the mucal, colourless diarrhœa, and the derangement of the urinary secretions which commonly follow cholera.—Dose, 3 to 10 gr.; in larger doses it proves laxative. See Calumba, &c.

BERENIZON (Dr Charles Wortley). A preparation for promoting the growth of the hair. Balsam of Peru 3 grammes, castor oil 3 grammes, tinct. cinchona 4 grammes, spirit 85 grammes, rosewater 40 grammes. (Schädler.)

BERG′AMOT. Syn. Bergamo′ta, L.; Bergamote, Fr.; Bergamotte, Fr., Ger. The bergamot-lemon, or fruit of cit′rus ber′ga′mia; also sometimes, colloquially, the fragrant oil obtained from its rind. See Oils (Volatile).

BERGBALSAM—MOUNTAIN BALSAM (of G. Schmidt, Berlin). Recommended for hemorrhoids, want of appetite, headache, constipation, &c. Rhubarb 2 parts, cortex frangulæ 10 parts, milfoil flowers (Achillea millefolium) 1 part, tansy 1 part, crystallised soda 112 parts; be digested for some hours in warm water, the fluid expressed made up to 26 parts, 30 parts of sugar dissolved in it, and

lastly mixed with 17 parts of rectified spirit. (Hager.)

BER′RY (bĕr′-re). Syn. Bac′ca (pl. bac′cæ, -sē), L.; Baie, Fr.; Beere, Ger. Any small succulent or pulpy fruit containing several naked seeds or granules. In botany, an indehiscent pericarp or seed-vessel, pulpy, many-celled, and many-seeded, the seeds being naked, and for a time connected by a slender membrane, from which they become detached at maturity, and then remain dispersed through the pulp. It is distinguished by its figure, &c., into several varieties.
