Laurel Leaf Oil (aromatherapy)

Laurel Leaf Oil is a pale yellow to very pale olive-green or almost colorless liquid of fresh, strong but sweet, aromatic-camphoraceous, somewhat spicy-medicinal odor. As a rule, the dryout notes of this oil are sweet, pleasant and slightly spicy, unlike those of eucalyptus, cajuput and, to a certain degree, myrtle oils. The two former oils are found occasionally as adulterants in commercial lots of laurel leaf oil. Chinese laurel leaf oil is distinguished by its very high content of eugenol (over 30%) which impairs the fresh notes of the oil significantly.
