This is a very sedative and antispasmodic group of molecules. Go to these oils first when deep relaxation, sleep, or relief from stress or anxiety is needed. Ester molecules often end in the word “acetate” such as Linalyl acetate (in Lavender angustifolia), Geranyl acetate (in Geranium), and Benzyl benzoate (in Ylang Ylang). These oils are skin friendly. Shelf life: 3-5 years.
