Memory: Rosemary essential oil is a stimulant, and using it in a diffuser or inhaling it directly from the bottle will enhance memory, alertness, and concentration. It will also reduce mental fatigue and sluggishness, and enhance mental clarity. These actions make it an excellent option to try for the cognitive issues associated with fibromyalgia and myalgic encephalomyelitis (chronic fatigue syndrome,) commonly called “fibrofog.”
Depression: Rosemary oil balances mood, lifts the spirits, and helps ease depression. It can be used in a diffuser, inhaled directly from the bottle, or applied to a tissue or handkerchief (one to two drops) and sniffed as needed. It can also be blended with a carrier oil such as cold-pressed olive or coconut oil at a concentration of two to five drops per teaspoon of carrier oil and applied to the body.
Stress: The same actions that make rosemary essential oil so useful for memory and depression make it an excellent choice for managing stress and stress-related issues. It helps you to see things more clearly, and calms and relaxes the nerves.
Acne: A 2007 study (PubMed ID 17893831) showed a specific anti-bacterial action against the bacteria that cause acne. A blend of rosemary and coconut oils, mixed at a concentration of six drops of rosemary oil in two teaspoons of coconut oil and applied after cleansing will help to reduce and control acne blemishes.
(See How To Use Coconut Oil To Clear Your Acne for more information about coconut oil and acne.)
Headaches: Rosemary oil, mixed at a rate of five drops to a teaspoon of cold-pressed olive or coconut oil, will help relieve the pain of both migraine and tension headaches. After blending, apply a single drop of this mixture to the temples, being careful to keep it well away from the eyes. The rest of the oil can be massaged into the back of the neck to reduce muscle tension, which will also help ease the headache.
Pain: Muscle and joint pain and swelling caused by arthritis, muscle spasms, strains or sprains can be reduced by the application of a blend of thirty drops of rosemary oil and two tablespoons of a cold-pressed carrier oil to the painful areas several times a day. (For even better results, use fifteen drops of rosemary essential oil and fifteen drops of lavender essential oil in your blend. The two oils together have a stronger pain relief effect than either of them used alone.)

Psoriasis, Eczema, and Dermatitis: Four drops of rosemary oil mixed with a teaspoon of cold-pressed carrier oil and applied to the rough, scaly patches of psoriasis, eczema or dermatitis will help reduce the itching and irritation, as well as promoting healing. Adding a drop of vitamin E oil will aid in healing as well, promoting the development of healthy skin cells and soothing cracked areas.

The breathing problems associated with asthma, bronchitis, colds, and sinusitis can be eased by using rosemary oil in a diffuser, but a better option is to add 3 drops of rosemary oil to a bowl of steaming hot water, using a towel to create a “tent” over the bowl and your head, and breathing the steam for no more than 5 minutes. (If your asthma reacts to strong smells, do NOT use this method, it could cause an asthma attack.) For asthma and bronchitis, a teaspoon of carrier oil mixed with 4 drops of rosemary oil can be applied to the chest instead.
