I keep hearing about how awesome essential oils are. To be honest, I’m not sure I quite believe all the hype BUT I think I do want to learn more and maybe try a few. I bought eucalyptus oil a few weeks ago but I don’t really know how to use it.

I’m most interested in oils that are:
* antifungal
* antiviral
* antibacterial
* mood balancing
* relaxing
* rejuvenating

Anyone have any experience and/or tips to share? What is a diffuser? Can I just put them in my humidifier? Are they safe for kids? What brands are cheap yet good quality (is that possible?)?
