Clary sage essential oil is steam distilled from the buds and leaves of the clary sage plant, a cousin to common garden sage. It’s native to Europe and is sometimes referred to as Muscatel Oil as it’s used to flavor muscatel wine. The herb has been used medicinally for centuries and was first described in writing in 4 BCE. Today, it’s known to be beneficial for treating depression, chronic stress and anxiety while helping to improve memory, concentration, focus and mental alertness.
Research in 2005 found that clary sage was able to enhance memory and cognition in patients with Alzheimer’s. The participants received single doses of the essential oil or a placebo, with those who received the clary sage reporting they felt calmer and more alert. In a separate clinical trial, the oil was found to improve mental alertness and offer cognitive support when inhaled.
