COMMENTARY. Although Galen and our author distinguish the _Amaracus_ from the _Sampsuchus_, there seems no reason to doubt their identity. See Needham (Ad Geopon. xi, 27); the Synonymes of Dioscor. (iii, 41); and Sprengel (ibid.) Dioscorides describes it (_Origanum marjorana_) minutely, and says its decoction is drunk with advantage in cases of dropsy, dysuria, and tormina; that its dried leaves, in a cataplasm with honey, remove suggillations; and that in a pessary it is emmenagogue. He also recommends it as an external application to the stings of scorpions, sprains, œdematous swellings, inflammations of the eyes, and as a calefacient ingredient in acopa and malagmata. (Ibid.) Galen and the other Greek authorities treat of it in general terms. For the Arabians, see Avicenna (ii, 2, 466); Serapion (c. 286); Rhases (Cont. l. ult. i, 439). They recommend it in the same cases as the Greeks; and also in hemicrania, vertigo, earache, in embrocations and injections. They also speak well of the oil of it as an application in cases of paralysis. The “Thymus Cyprius” of Celsus is set down by C. Bauhin as being the _Thymus mastichius_; but whether it be any other than the marjoram seems doubtful, although Celsus certainly mentions them as distinct substances. (v, 11.) Compare our account of this article with what Quincy says of the marjoram in the ‘Complete English Dispensatory’ (60.) Σανδαράχη, Sandaracha, _Red Arsenic_, is possessed of caustic powers like orpiment. * * * * *
