Calamus essential oil information

Calamus oil has a warm, spicy odor – reminiscent of a sweet forest.


It is a perennial, semi-aquatic, marshy plant, native to northern Europe and Asia.
The root of this plant is used in herbal medicine for the treatment of nervous complaints, vertigo, headaches, neuralgia, shock, epilepsy, panic attacks and dysentery.


This essential oil is extracted from the fresh roots or the unpeeled dried root by steam distillation.

IFRA recommends that this oil be avoided for use in fragrances and that the level of asorone in any product should be kept lower than 0.01%. IFRA also suggests that the level of Methyleugenol be kept lower than 0.0004% in any leave-on product (face cream or body creams and lotions).

Calamus oil is known to be one of the oils mentioned in the bible in Exodus 30. We make a blend called Exodus 30 Anointing Blend, which includes this oil at an EXTREMELY low percentage.
