COMMENTARY. The high interest which attaches to these articles might well dispose us to wake our classical recollections, in order to illustrate the nature of them, if the narrow limits to which we feel that we are restricted did not restrain us from such an undertaking. We beg, however, to quote the words of one of our ablest authorities in illustration of this subject. Dr. Lindley, treating of the plants which yield assafœtida, says, “assafœtida is the milky juice of various species of Ferula inhabiting Persia and neighbouring countries. Of these, F. assafœtida is the plant described by Kæmpfer. (Amæn. Exot. 535); but F. Perscia and others, are no doubt also the origin of this drug. The Asa dulcis or Laser Cyrenaicum was yielded by a Thapsia, and probably _Thapsia Garganica_. This drug was in high reputation among the ancients for its medicinal uses; it had miraculous powers assigned to it—power to neutralize the effect of poison, to cure envenomed wounds, to restore sight to the blind, and youth to the aged; these were only a part of its reputed properties; it was also reckoned antispasmodic, deobstruent, diuretic, &c., &c. So great was its reputation, that the princes of Cyrene caused it to be struck on the reverse of their coins; and the Cyrenean doctors were reckoned among the most eminent in the world.” (Veg. King. 776.) See further Pereira (Mat. Med. 1041), and most especially Sprengel in Dioscor. (iii, 85.) From what we have stated, our readers will readily comprehend that the Median and Syrian juices were varieties of the gum resin of Ferula assafœtida; while the Cyrenean juice was the gum resin of a congener, namely (as stated above), the _Thapsia Garganica_, called silphium by the ancients. That the Cyrenaic juice was the product of the silphium, is positively stated by Strabo. (Geogr. xvii, 3.) We shall reserve what we have to say on its medicinal properties till we come to that article. It is the laser and laserpitium of the Roman authors. It occurs in the Hippocratic collection. (De Morb. iv.) By the Arabian authors it is generally treated of under the name of _Assa_, and hence its modern appellation. Ὀρίγανος, Origanum, _Origany_, or _Wild Marjoram_; all the species of it are possessed of incisive, attenuant, desiccative, and calefacient powers in the third degree. * * * * *
