By steam distillation of the flowering herb, an essential oil is produced in Texas, U.S.A. Oil of sweet goldenrod is a colorless, rather mobile liquid of sweet spicy, aromatic herbaceous odor, reminiscent of estragon (Tarragon). The odor is inferior to that of estragon in respect to sweetness, tenacity and delicate, green foliage notes. The rather simple or homogeneous odor of goldenrod oil is probably the main reason why the oil has never become a big item on the perfumer's shelf. It does not present any significant advantage over estragon oil or over the main constituent, methyl chavicol (estragole) and it has no fresh green topnote, such as we find it in sweet basil oil.
