Essential oils have been used to treat a variety of symptoms and diseases for thousands of years. They can be administered via inhalation, known as aromatherapy, or topically with or without massage treatment. Neroli oil, also called bitter orange, treats a wide variety of problems and is most commonly used as an anti-depressant, aphrodisiac, antiseptic, deodorant, emollient or sedative.
Mix concentrated neroli oil with a carrier oil or cosmetic base or cream. Dilute essential oils in a carrier oil to produce a concentration of no more than 3 to 5 percent, says Linda Halcon, Professor of Nursing at the University of Minnesota. A 3 percent solution would be equal to 3 drops of essential oil for each teaspoon of carrier oil. Some high-quality carrier oils include cold-pressed grape seed, wheat germ, olive, vegetable or sweet almond oil.
Rub neroli oil on the feet first. This allows the body to get used to the temperature of the oil and starts the aromatherapy process.
Apply neroli oil to fungal infections on the skin. Neroli oil can be used as an antifungal. Apply it to the skin for relief from conditions like ringworm or athlete's foot, according to the National Center for Complementary and Alternative Medicine.
Rub the neroli massage oil on stretch marks, age spots or scars. Neroli oil is known as a cicatrisant, or an oil with anti-scarring properties. Neroli oil helps stimulate skin cells to regenerate, which helps eliminate scars or stretch marks, says Patricia Davis, author of "Aromatherapy: An A-Z."
