Is the Loasa genus or the Ferula genus more useful to humans?
Ferula Ferula (from Latin "ferula", "rod") is a genus of about 170 species of flowering plants in the carrot family, native to the Mediterranean region east to central Asia, mostly growing in arid climates. They are herbaceous perennial plants growing to 1–4 m tall, with stout, hollow, somewhat succulent stems. The leaves are tripinnate or even more finely divided, with a stout basal sheath clasping the stem. The flowers are usually yellow, rarely white, produced in large umbels. Many plants of this genus, especially "F. communis" are referred to as "giant fennel," although they are not fennel in the strict sense.
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.
