Rosewood Essential Oil that is available in stores is usually extracted from the Brazilian Rosewood tree (Aniba rosaeodora). There are many other types of trees that are called Rosewood, including many species from the family Dalbergia. Rosewood Essential Oil is isolated by steam distillation of the wood and bark.
Rosewood Essential Oil is not commonly used in the Naturopathic treatment of acne. When Rosewood Essential Oil is used to treat acne, it is generally diluted and added to topical preparations. Rosewood Essential Oil is mildly toxic to many gram-positive bacteria, including acne-causing Propionibacterium acnes. There is very little clinical research and few patient reports about the efficacy of Rosewood Essential Oil for improving acne symptoms.
The primary molecular component of Rosewood Essential Oil is Linalool. Linalool is a volatile molecule that is very aromatic and accounts for up to 85% of the total oil content. Linalool can irritate the skin and cause allergic reactions in some individuals.
Rosewood Essential Oil is used extensively in perfumes and aromatherapies. Rosewood is more expensive than most other essential oils because of limited supply. The Brazilian Rosewood tree is endangered, but because the farmed supply of Brazilian Rosewood is not sufficient to meet demand, wild trees continue to be harvested.
