Use
Calamus oil (sweet flag oil) is obtained by steam distillation of fresh or
unpeeled, dried roots of Acorus calamus L. (Araceae). It is a yellow to medium
brown, moderately viscous liquid with a pleasant, spicy, aromatic odor.
Calamus oil is used in perfumery for spicy, herbaceous notes.However, its use is
restricted because of the toxicity of β-asarone (see corresponding IFRA standard).
In some countries (e.g., the United States, EU), the use of calamus oil is banned
for application in food flavorings and in food. Due to these problems, the oil is
produced just on a very small scale, for example, in India.
