Adverse skin reactions In a modified Draize procedure on guinea pigs, Re´union vetiver oil was assessed as sensitizing. Undiluted vetiver oil was moderately irritating to rabbits, but was not irritating to mice; tested at 8% on 25.
volunteers it was neither irritating nor sensitizing. It is nonphototoxic In a study of 200 consecutive dermatitis patients, one was sensitive to 2% vetiver oil on patch testing. A 65-year-old aromatherapist with multiple essential oil sensitivities reacted to both 1% and 5% vetiver oil.

Comments
The composition given above is a composite of essential oils produced in nine countries. These can be divided into three subgroups, two consisting of four countries each, with Madagascar comprising a third group. Only vetiver oils from Java, China, Brazil and Mexico contain any isoeugenol. Those from Haiti, India, Reunion and El Salvador are devoid of isoeugenol, as is the oil from Madagascar. There are distinct variations in the content of khusimol, b-vetivenene and b-vetispirene between the three subgroups, but overall vetiver oils are relatively homogenous. Vetiver oil is also produced in small amounts in Angola and The Seychelles. The oil is a complex mixture of over 150 sesquiterpenoid compounds, some of which have not yet been identified.
