Make Your Own Hand Sanitizer

I don't know about your area, but stores are sold out of hand sanitizers in my town due to the public panic over Swine Flu.  Also gone from store shelves are the disposable face masks.  While it seems these would be effective, in fact all they do is protect others from catching what you've got and they are often loose-fitting and most likely won't protect the wearer from inhaling small particles.  

Hand washing is essential.  Do it often. And for a minimum of 20-30 seconds.  If you're on the go, bring along an alcohol-based hand sanitizer.  If you can't find any in stores anymore, make your own. This one includes an ingredient (tea tree oil) that has antibacterial AND antiviral properties.  

1 cup aloe vera gel
1 tsp rubbing alcohol
2 tsp vegetable glycerine
8-10 drops tea tree essential oil or lavender essential oil
