QUESTION: Which oils are useful when there are cold germs around?
ANSWER: When there are cold germs around my house, I use Cajeput, Eucalyptus, Lavender, Peppermint, Pine, Rosemary, Sandalwood, Thyme and Tea Tree. Some of these oils come with safety cautions (see Safety Information) that would apply even if you were just to diffuse them in a room so it’s best to know a little about them before using.
