Beschreibung

Bulnesia sarmienti Lor. is a wild tree 3 to 4 m (10 to 13 ft.) high, widespread in the woods of Argentina and in the Gran Chaco area of Paraguay. This variety yields the true guaiac, Guaiacum officinale L., also a tree native to tropical America (Caribbean Islands), grows wild or cultivated in Venezuela, Jamaica, Cuba, and Colombia. This variety yields a resinous substance from which a tincture is prepared. The wood and sawdust from the tree are the parts used. Guaiac has a soft, pleasant, rose-like odor reminiscent of tea roses.
The essential oil is obtained by steam distillation of chipped wood of B. sormienti in approximately 3% yields. It is a thick, viscous, orange-brown mass with a woody, rose-like odor reminiscent of tea rose. Sometimes the oil exhibits a smoky note. The main constituent of the oil, also known as champaca wood oil, is guaiol, a sesquiterpene alcohol (85%).
