Galbanum is an aromatic gum resin and a 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. In the Book of Exodus 30:34, it is mentioned as being used in the making of the Ketoret which is used when referring to the consecrated incense described in the Hebrew Bible and Talmud. It was offered on the specialized incense altar in the time when the Tabernacle was located in the First and Second Jerusalem Temples. The ketoret was an important component of the Temple service in Jerusalem. Rashi of the 12th century comments on this passage that galbanum is bitter and was included in the incense as a reminder of deliberate and unrepentant sinners. It is occasionally used in the making of modern perfume, and is the ingredient which gives the distinctive smell to the fragrances “Must” by Cartier, “Vent Vert” by Balmain, “Chanel No. 19” and “Vol De Nuit” by Guerlain. The debut of Galbanum in fine modern perfumery is generally thought to be the origin of the “Green” family of scents, exemplified by the scent “Vent Vert” first launched by Balmain in 1945. Hippocrates employed it in medicine, and Pliny (Nat. Hist. xxiv. 13) ascribes to it extraordinary curative powers, concluding his account of it with the assertion that “the very touch of it mixed with oil of spondylium is sufficient to kill a serpent.” Its fragrance profile is intensely green, potent, powerful, sharp, cut grass, parsley leaf, parsley tea, green wild leaves in the winter in the Wadi, dirt, balsamic, fresh. Hints of powder (tingle in the note – sharp powder like ground glass, not soft). Hints of pine, woods, peppery, elemi-like balsamic. (from Wikipedia)
