Niaouli is a strong antiseptic,antibacterial oil. It also has strong decongestant properties, which make it appropriate for treating head and chest colds . In addition, it helps clear the head mentally, as well, since it has a stimulating and uplifting effect. For a daytime respiratory blend, try mixing it with peppermint, eucalyptus, and either pine or fir. A really energizing blend when you are fighting a cold and want to stay in bed, but can't.
Some sources recommend it for fighting acne, boils, and other skin infections.
I have also seen it recommended for treating cystitis. Steam distilled, fruit. Nutmeg oil smells exactly like the fresh ground spice, warm and welcoming. It needs to be used with caution as some authorities state it has psychotropic effects and is a hallucingen. Battaglia, however, states that the hallucigenic qualities are present in the spice, but not the distilled oil.
