COMMENTARY. There can be no doubt that it is the _Alisma_ of Dioscorides, and therefore probably the elegant water plant now called _Alisma Plantago_. On this point see Gerarde, Parkinson, Cordus, and Sprengel. Dioscorides recommends its root in cases of poisoning by the sea-hare, the red frog, and by opium; in tormina and dysentery when drunk by itself and with carrot; and in convulsions and hysterical complaints. He adds, that the herb binds the belly, is emmenagogue, and softens swellings when applied. (iii, 159.) Galen states that he had never any experience of it in the cases mentioned by Dioscorides; but that he had found it possessed of lithontriptic powers. The other Greek authorities follow him. The Arabians copy from both. See Avicenna (ii, 2, 244, 249); Ebn Baithar (ii, 513.) Δαῦκος, Daucus, _Carrot_ (called also Staphylinus), consists of two varieties. The root of the cultivated carrot is flatulent and aphrodisiacal; the seed of the wild is wholly devoid of flatulent properties, is diuretic and emmenagogue; and so in like manner the stem. * * * * * COMMENTARY. Of the three species of _Daucus_ described by Dioscorides (iii, 76), the leaves of the first are compared by him to those of the fennel; the leaves of the second to those of the wild parsley; and the leaves of the third to those of coriander. The first is the species which was long known in this country by the name of Candy carrots, and which has obtained various names of late years from our botanical authorities. It seems now settled that it should be called _Athamanta Cretensis_. “The second,” says our indefatigable herbalist, old Parkinson, whose practical acquaintance with all sorts of plants entitles his opinion to high consideration, “is acknowledged to be so like the first that the climate and country only make the difference.” It is now called _Athamanta cervaria_. The third, or coriander-leaved daucus, as the same authority clearly indicates, was probably a species of _seseli_. It, however, is not very certainly determined. The following description of their medicinal virtues by our Quincy may be said to embody the concurrent opinions of all the ancient authorities, Greek, Roman, and Arabian. “The seed is aperient and good in disorders of the kidneys; as also to hasten delivery, and bring away the after-birth. It is likewise accounted a good alexipharmic, and proper against the bites of venomous creatures.” See Avicenna (ii, 2, 214, 287); Ebn Baithar (ii, 462); Celsus (v, 23); Hippocrates (De Ratione Vict. in Acut.); also under Staphylinus. Δάφνη, Laurus, _The Bay-tree_; its leaves are powerfully desiccant and calefacient, but its fruit still more so. The bark of its root, being bitter and sub-astringent, proves lithontriptic and cures hepatic affections when drunk to the amount of three oboli with fragrant wine. Δάφνη πόα,
