Commelina.

Commelina. Day-flower.—Under the name of Yerba del Pollo, Commelina tuberosa L. is said to be very largely used in Mexico in the treatment of internal hemorrhage, especially from the womb. From thirty to sixty grains (2.0-3.9 Gm.) of the extract may be taken in the course of one day. (See A. J. P., 1897, 290.) The North American species, Commelina communis L., has also had hemostatic properties attributed to it. For chemical and microscopical study, see A. J. P., July, 1898.
