Menstrual cramp / dysmenorrhea relief

Limited Evidence

Small trials of clary sage aromatherapy (often combined with other oils) suggest reductions in menstrual pain.

Anxiety / stress

Limited Evidence

Small clinical studies show modest cortisol reduction and improved mood with aromatherapy use.

How it works

Clary sage essential oil's primary aromatic components are linalool, linalyl acetate, and sclareol. Sclareol has weak estrogen-like activity in vitro, and aromatic use is hypothesized to influence mood via olfactory pathways. Clinical studies of clary sage aromatherapy suggest possible benefits for menstrual cramps, anxiety, and mood. Inhalation of the essential oil has been associated with decreases in cortisol and blood pressure in small trials.

Dosage

Essential oil: aromatherapy diffusion 3-5 drops; topical use diluted to 1-3% in carrier oil. Internal use of clary sage essential oil is not recommended. Tea from dried herb: 1-2 g.

When and how to take it

WHEN: Aromatherapy use before bed for relaxation or during day for mood support. HOW: Diffuse, dilute for topical use, or steep dried herb as tea.
