Galbanum

Galbanum (mother resin, galbanum gummiresina ) of the dried latex of Ferula erubescens, an umbel plant Persia and the area is east of the Aral Sea.

Goods coming over the Levantine harbors from Syria, Persia, Arabia, partly from the East Indies and forms as some other such drugs two varieties, tears or grains and masses or cakes, the former in brighter, white or yellowish, translucent, wax- shiny, pea to nut-sized grains, the latter interspersed in darker, brownish or greenish clumps of bright grains.

The substance is quite soft and sticky, pulverizable only in the cold. It contains about 60 percent ethanol-soluble resin, rubber and 20 percent to 6 percent essential oil (Oleum Galbani ) from which it takes a penetrating unpleasant aromatic odor. The taste is bitterish acrid, burning. By distillation with water, the oil is obtained as a colorless, air- to tanning and thickening liquid that smells stronger than the resin, bitter and camphor taste.

The Galbanum has little importance for technical purposes; it is sometimes found listed as part of kittens (so-called Diamantleim ). Medically, the oil and the purified and powdered resin is internally and the latter externally applied as a softening agent for ulcers and tumors, and is the main component of the mother patch.
