Sida. Mesbe. Sida rhombifolia L.—Queensland hemp (Fam. Malvaceae), jelly leaf, is largely used in Australia as a demulcent. It contains a large quantity of mucilage. The fluidextract has been asserted to possess expectorant properties and to be especially valuable in the treatment of pulmonary tuberculosis. Zink (M. M. W., 1912), however, was unable to obtain evidence of any specific action in tuberculosis. Sida paniculata L. (S. floribunda H. B. K.), of Peru, which also contains a large quantity of mucilage, is said by Martinet to be a very active vermifuge, owing its powers, probably, to the extremely minute but very resisting spines which cover its leaves, the part used.
The Dispensatory of the United States of America, 1918, was edited by Joseph P. Remington, Horatio C. Wood and others.
