What is a staple in the koala bear's diet as well as a mainstay in body care products? Well, that would be eucalyptus, of course. For years it was synonymous with mentholated rub, but body care makers have more recently adopted it into their products because of its pungent yet pleasant scent and multiple beneficial properties. If used in its essential oil form, it's great for both clearing up a stuffy head and cleaning a wound. There were some early adopters, but now you'll find it in a lot of body care lines.
