A resinous and gummy juice that exudes from the Bubon galbanum. The commercial article is in the state of white, yellow, and brownish tears, unctuous to the touch, and softening between the fingers, and generally full of bits of stalks, leaves, etc. of the plant; it has a bitter acrid taste, and strong smell. One pound of galbanum yields to alcohol nine and a half ounces of resin, and to water about three ounces of gum. The peculiar smell and taste of galbanum reside in an essential oil, six drachms of which are obtained by distillation from one pound of the substance.
