Med. Prop. and Action. The dark red mealy powder mixed with the hairy spiculAe brushed from the outer surface of the capsules, possesses considerable power as an anthelmintic. The first notice of its use in this character, it having previously been employed largely as a dye, occurs in Royle's " Illustrations of Himalayan Botany, " published in 1839, but it attracted little notice till 1853, when Dr. C. Mackinnoni, recorded several cases of TAenia successfully treated by its use. These results were fully confirmed by Dr. T. Anderson,§ who furnishes a good account of its physiological action: he found that on an adult, the powder in a dose of 3ij. - 3ss., in addition to purging, frequently caused nausea and vomiting, and in some cases griping. Its action on the bowels, however, was found to be very variable. A strong etherial or alcoholic tincture, besides acting more mildly, was found to bo followed by more uniform effects; and a dose of the tincture sufficient to produce the full anthelmintic effects of the drug was found never to be followed by more than six stools unattended with griping, or with any observable effects on the pulse or nervous system. The only objection to it is, that when the powder is used considerable nausea occasionally follows, although this does not appear to be more than that produced by pomegranate and other anthelmintics. Dr. Anderson also observed that, after 3iij. of the powder had been administered the worm was usually expelled in the third or fourth stool, generally entire and almost always dead. Its action appears to be principally confined to Taenia. In cases of Lumbrici it seems to exercise very little effect beyond that of an ordinary purgative. Its value as an anthelmintic has been confirmed by Drs. C. A. Gordon,|| Ramskill,¶ Leared,** and others. On the other hand, it is esteemed as inferior to the Oil of Male Fern, by Dr. Peacock, and it has fallen in the estimation of others. The dose of the powder is gr. cl - gr. clxxx. for an adult, and it is unnecessary to give any other medicine before or after. Of the Alcoholic Tincture (oz. vj. - Sp. Rect. Oj.), the dose is fl. oz. ss., either in one or two doses, with some aromatic water. The natives of India employ an ointment of Kamela externally in itch and other skin diseases (Mackiunon); and Dr. W. Moore* states that in Herpes arcinatus he found the Kamela applied on moistened lint an effectual cure. He considers that it may prove useful in other allied eruptions.
