What is rosemary oil good for?

Rosemary has long been used for cooking and for medicinal purposes. Rosemary essential oil has an invigorating aroma that energises both the mind and the body. It is one of the most versatile oils in aromatherapy.

Its antioxidant, antimicrobial and stimulating properties make rosemary a multipurpose herb. People use it to improve brain function, promote skin clarity, support hair growth and energise circulation. Its fresh, camphor-like scent comes from natural compounds such as 1,8-cineole (eucalyptol) and camphor.

4 benefits of rosemary essential oil

1. Brain function, focus and memory

Rosemary is one of the best-known oils for the brain. In one study, inhaling rosemary led to a significant increase in memory recall of images and numbers. The volunteers felt refreshed, and the results showed a stimulating effect on brain wave activity.

To enjoy these rosemary oil aromatherapy benefits, diffuse it in your workspace. Many people find it helps focus, concentration and mental clarity.

2. Skin care: acne, scars and inflammation

Rosemary might be one of the most undervalued oils for skincare, but it could be your skin's best friend. It is an excellent source of antioxidants and has antimicrobial properties (Nieto, Gema et al., 2018).

It also stimulates local blood flow, skin-cell regeneration and lymphatic drainage. These properties make rosemary essential oil a strong choice for relieving acne, scars and inflammation. For the face, always use it well diluted in a serum, like the recipe below.

3. Hair growth and a healthy scalp

Rosemary's stimulating action makes it a staple in hair care and growth routines. It has been used in Mediterranean traditions to treat a dry scalp, itchiness and dandruff.

In one study, rosemary essential oil promoted hair growth in mice. More research is needed, but it is a promising natural option for hair vitality and strength. Read more in our guide to rosemary oil for hair growth.

4. Circulation and energy

Rosemary is stimulating and revitalising, which makes it a top choice for circulation. One study showed that inhaling rosemary increased heart rate, blood pressure and breathing rate, while lifting mood and alertness.

Healthy circulation helps relieve muscle tension and fatigue. A diluted rosemary massage oil or a lemon and rosemary bath are easy ways to enjoy it.

Rosemary blends beautifully with citrus, mint and woody scents. Its sharp, herbal note works best when you soften it with something sweet or round it out with something warm.
