Mucuna urens

Natural History.
      Mucuna urens.
      Horse-Eye. (Hot regions of Venezuela.) N.O. Leguminose. The pulverized bean is macerated five times its weight of alcohol.

      Hemorrhoidal discharges.

      In New, Old, and Forgotten Remedies (p. 220) is a letter by Delgado Palacios, of Venezuela, pointing out that the name Dolichos, given to Cowhage of Cow-itch in homeopathic literature (see Vol. I.), is not in accordance with latest botanical terminology.
      Cowhage is really a Mucuna, Mucuna and Dolichos being separate genera of the Leguminose. They are so described in the Treasury of Botany. (Allen given Linneus as the authority for the name Dolichos pruriens.) Palacios has used M. urens, with which, he says, modern botanists consider Cowhage identical, but he does not name his plant M. pruriens, an alternative name of Cowhage, and as he says, further, that M. urens is a "special plant which grows in the calid regions of Venezuela," and that the beans are "very difficult to obtain," I think it best to give the plant a separate notice.
      This is the more desirable as Palacios uses an entirely different preparation.
      In Dolichos (I retain the name for the sake of distinction) the entire pod is used, the stinging hairs being the most important part of it.
      Palacios uses the pulverized bean for making his tincture.
      His chief use for it is in hemorrhoids and complaints arising from the hemorrhoidal diathesis.
      The keynote symptom is burning.
      There may or may not be bleeding.
      Affections of liver, uterus, bladder, testicles, when accompanied by hemorrhoids, are likely to be cured by M. urens.
      He gives one drop daily of the f tincture, and sometimes makes an ointment of it as well, He places more reliance in it than in Hamamelis and Escul. h. There is no pathogenesis.
