Balote, by some called _Black Horehound_; it is possessed of acrid and detergent powers; therefore, when applied with salts, it relieves the bite of mad dogs. * * * * * COMMENTARY. There appears little reason to doubt that this is the _Ballote nigra_, or stinking horehound of our herbalists. Our author’s account of it is abridged from Dioscorides. It is not treated of by Galen, Aëtius, nor Oribasius, neither is it found in Celsus. Avicenna and Ebn Baithar we believe are the only Arabians who notice it, and they copy from Dioscorides (ii, 2, 553, and i, 166.) Βάτος, Rubus, _the Bramble_; its shrubby part is moderately astringent and desiccant, and therefore agglutinates wounds and stops defluxions. The root, in addition to its astringency, is attenuate in no small degree. It therefore breaks down renal calculi. Its ripe fruit is hotter, and has a moderate astringency. It is therefore edible; but the unripe is sour and powerfully desiccant, more especially if dried. In like manner also the flower. * * * * * COMMENTARY. The first species of bramble described by Dioscorides is probably that well-known one the _Rubus fruticosus_, the other is the _Rubus Idæus_, or raspberry bush. The Β. Ἰδᾶιος of Dioscorides was supposed by Ruellius and others to be the _Fragaria_ or _Strawberry_, but with this supposition we cannot agree. Strawberries are not noticed by any Greek writer, but are first mentioned by Ovid (Met. i, 104); and then by Pliny (H. N. xxv, 62.) The μόρον βατῶδες, of which mention is occasionally made by our author, was the fruit of the bramble, being so called, according to Eustathius, from its resemblance to mulberries. (Ad Iliad. xiii, 121.) Our author abridges Galen, who is at great pains in defining the powers of the batos, which he makes out to be moderately astringent and desiccative; and hence he pronounces it to be useful in dysentery, fluxes of the bowels, atony, hæmoptysis, and in calculus as a lithrontriptic. Dioscorides indulges in a still more lengthened exposition of its virtues, recommending the decoction of it as an astringent in looseness of the bowels, and in fluor albus, as an antidote to the sting of the serpent Prester; its leaves when chewed, to strengthen the gums and cure the aphthæ of children, and externally, for the cure of herpes, achor, procidentia oculi, and many other diseases (iii, 36.) It is briefly alluded to by Celsus in treating of lientery (iv, 16.) The Arabians, as usual, copy from Dioscorides and Galen. See Serapion (De Simpl. 124); Avicenna (ii, 2, 572.) The rubi held their place and ancient characters in our Dispensatories down to a late date. See Quincy (p. 94.) Even yet several of the rubi are still kept in the shops for medicinal purposes.
