To reduce my electric heating bill recent years, I wear ONE warm hat indoors, TWO pairs of heavy socks and THREE jerseys and sweaters; then I keep my thermostat around 60 degrees. We are overly dependent on heating our homes. Living in a cooler indoor environment means fewer colds also! (However, I wear three pairs of socks while temps are in the teens to twenties!). Taking grapefruit seed extract (GSSE) daily has reduced my colds. In the last 11 years I have only been sick three times from colds or flu taking a few drops a day of GSE in juice daily (NEVER take it straight or in water, too sour that way!).
It is effective against 800 viral, fungal, bacterial and parasitic infections. See Nutriteam.com for its multifarious uses in health, water disinfecting and agriculture.
