Obtained from the fresh ground part of the wild plant Zdravetz (Geranium macrorrhizum) through steam distillation.
In perfumery, it constitutes the perfume base and compositions thanks to its good fixation capacity.
Major component of this oil is the germacron which produces stearopteneq also other sesquiterpene ketones, sesquiterpene hydrocarbons, and alcohols, monoterpene compounds. Azulenes give the green color of the oil.
