Ἀπόχυμα,
Apochyma, is the old pitch scraped from ships. It is solvent, desiccant, and discutient of tumours.
Commentary. Dioscorides calls it also Ζωπίσσα. It consists, as he explains, of the wax and pitch of ships which had been macerated in salt water. Pliny says of it, “Zopissam eradi navibus diximus cera marino sale maceratâ. Optima hæc a tirocinio navium. Additur autem in malagmata ad discutiendas collectiones.” (H. N. xxiv, 26.)
Ἀράχνη,
Aranea, the Spider, when softened into a plaster, and applied to the forehead and temples, is said by Dioscorides to remove the periodical attacks of tertians. Its web, when applied, stops hemorrhage, and preserves superficial sores from inflammation.
Commentary. Dioscorides describes two species, which probably are the Aranea retiaria, and the Aranea domestica. Serapion gives the same account of their medicinal properties. They appear to have been principally used externally, as an anti-inflammatory application.
Ἀργεμώνη,
Argemone, Prickly Poppy, is possessed of detergent and discutient powers.
Commentary. Of the two species described by Dioscorides, the former, which is the Papaver argemone, is recommended by him in nebulæ and albugo of the eye, and its leaves as a soothing cataplasm for inflammations. The other, which may be the Geum urbanum, or avens, he also recommends principally as an external application in sores and affections of the eyes; but adds of it, that when drunk with wine it is useful in the case of persons stung by venomous animals. (ii, 208.) Galen and the succeeding authorities treat of it more cursorily; and the Arabians would seem not to treat of it at all, with the exception of Ebn Baithar, who merely gives translations of what Dioscorides and Galen had written of it. (i, 28.)
