Have a big test coming up or a work project due? Rosemary's bright, refreshing aroma is a classic study companion.
Rosemary has delicate lavender-blue to purple flowers and highly fragrant, needle-shaped leaves. The oil is steam distilled from the plant’s flowering tops and leaves.
About Rosemary Essential Oil
The scent of rosemary is penetrating, fresh and camphoraceous, with hints of peppermint and eucalyptus. The aroma alone is invigorating to the mind and body. It is also a favorite in hair care blends.
Many people diffuse rosemary to stay alert and focused while studying or working on projects, and to feel refreshed after a long day.
Rosemary (Rosmarinus officinalis) is an aromatic plant in the same family as mint, oregano and thyme. Its aroma is often described as:
- Energizing
- Clarifying
- Fresh and clean
- Uplifting
- Herbaceous and green
Rosemary oil is rich in 1,8-cineole and alpha-pinene, which give it its fresh, clearing scent.

Rosemary Safety
- Avoid diffusing rosemary around children under 10. Like eucalyptus, it is high in 1,8-cineole, which can affect young children's breathing.
- If you are pregnant, have epilepsy or have a medical condition, check with your doctor before using rosemary.
- Diffuse in a ventilated room and keep diffusers in rooms that cats, birds and other pets can leave.
Diffuser Safety Guidelines
Diffuse for 30 minutes to 1 hour at a time. Read more about how long to diffuse oils.
Don't apply undiluted essential oils to the skin. When using essential oils topically, dilute them in a carrier oil like jojoba or sweet almond oil.
Everyone responds to essential oils a little differently, so what works for one person may not work for you. Learn more about what to do when essential oils don't work.
