Rosemary essential oil is a good all rounder but particularly studies have shown that it may help memory, relieve mental fatigue and lethargy. Its a very useful oil to smell during exams and is also great to alleviate that Monday morning feeling.
Rosemary has a warm, penetrating and stimulating odour making it a must for muscle ease. Superb after sports activities - even more so when combined with Lavender and Marjoram. Dilute well in a carrier oil before skin application.
Rosemary has also traditionally been used in skin and hair care. It's a good toner and can be rejuvenating for the scalp. You can add it to your shampoo - it makes an excellent rinse for dark hair and hair in poor condition.
NB: Do not use if you suffer from high blood pressure
