Clary sage is a Mediterranean shrub from the salvia family with a looooong medical history—its uses can be found in the writings of Theophrastus (4th century BCE) and Pliny the Elder (1st century CE). It has been documented for use as a hormone-regulating her, used by women dealing with things like menstrual cramps and other hormonal imbalances.  
The chief components of clary sage essential oil are sclareol, alpha terpineol, geraniol, linalyl acetate, linalool, caryophyllene, neryl acetate and germacrene-D.
The clinical uses for clary sage oil are manifold: it’s been demonstrated to have antioxidant antidepressant, antifungal,  anti-infectious, anti-microbial and anti-inflammatory properties. Combine that with its hormone-regulating actions, and this is a great herb for hormonal acne.
