No sinus infections in the house for years. When we get stuffed up we get relief in under a minute, and 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/ sleep with. When it is all of us I put 20 drops or so with a cup or 2 of water and simmer on the stove for a few hours. That also prevents colds from spreading(anitbacterial and antiviral). One person I know puts it in her vacuum when she vacuums.
GREAT IDEA!! NO BUGS!! All you need is a package of Mason jars, some cotton string and some liquid citronella (find it in big jugs at any home-improvement store and even some grocery stores). Use a hammer and nail to poke a hole in the top of the lid, then pour in the citronella, put the top on and drop in the wick. Allow the string about 10 minutes to soak up some oil.
