No sinus infections in the house for years! When we get stuffed up we get relief in under a minute & it doesn't settle or move into the chest. Inhale it from the bottle, or put a few drops on a tissue or cotton swab to carry around or sleep with. Put 20 drops or so with a cup or 2 of water & simmer on the stove for a few hours. Also prevents colds from spreading (anitbacterial & antiviral).
