Galbanum Galbanum is an aromatic gum resin, the product of certain umbelliferous Persian plant species in the genus "Ferula", chiefly "Ferula gummosa" (synonym "F. galbaniflua") and "Ferula rubricaulis". Galbanum-yielding plants grow plentifully on the slopes of the mountain ranges of northern Iran. It occurs usually in hard or soft, irregular, more or less translucent and shining lumps, or occasionally in separate tears, of a light-brown, yellowish or greenish-yellow colour, and has a disagreeable, bitter taste, a peculiar, somewhat musky odour, an intense green scent, and a specific gravity of 1.212. It contains about 8% terpenes; about 65% of a resin which contains sulfur; about 20% gum; and a very small quantity of the colorless crystalline substance umbelliferone. It also contains α-pinene, β-pinene, limonene, cadinene, 3-carene, and ocimene.
