Olibanum Pharm. Lond. & Edinb. Oli-banum: a gummy resin brought from Turkey and the East Indies, usually in drops or tears like those of mastich, but larger, of a pale yel-lowish colour, which by age becomes reddish. It is the product of a tree of the juniper kind growing in Arabia; the juniperus lycia of Linnaeus.
This gummy-refin has a moderately strong, not very agreeable smell, and a bitterish some-what pungent taste: in chewing, it sticks to the teeth, becomes white, and renders the saliva milky. Laid on a red-hot iron, it readily catches flame, and burns with a strong, diffusive, not unpleasant smell: it is supposed to have been the incense used by the ancients in their religious ceremonies, though it is not the sub-stance now known by that name in the shops. On trituration with water, greatest part of it dissolves into a milky liquor, which on standing deposites a portion of resinous matter, and being now gently infpiffated, leaves a yellow extract, which retains greatest part of the smell as well as the taste of the olibanum; its odorous matter appearing to be of a less volatile kind than that of most other gummy-refins. Rectified spirit dissolves less than water, but takes up nearly all the active matter: the transparent yellowish so-lution, infpiffated, yields a very tenacious resin, in which the active parts of the juice are so enveloped and locked up, that they are scarcely to be discovered, either by the smell or taste.
Olibanum is recommended in disorders of the head and breast, in haemoptoes, and in alvine and uterine fluxes: the dosfe is from a scruple to a dram or more.
