Corylus. Corylus rostrata Ait. Beaked Hazel.—This is a small indigenous shrub of the Fam. Betulaceae, growing especially in mountainous districts. The nut is invested with a scaly involucre, projecting beyond it like a beak, and thickly covered with short spicules like those of Mucuna pruriens DC. (Fam. Leguminosae.) These spicules have been employed by Huebener as an anthelmintic. They operate in the same way as cowhage, and may be administered in the same manner and dose. (See A. J. P., xiv, 280.)

According to Baruttan and Davidsohn (M. M. W., 1909, p. 2482), the hazel-nut contains an alcoholic soluble substance which acts as a stimulant to the uterine muscle. An alcoholic extract is placed upon the market under the name of mensan which these authors have found useful in the treatment of uterine hemorrhages due to chronic endometritis. The dose employed was a tablespoonful twice a day.
