Eucalyptus oil
<p>Apart from essential oils used mainly in foods, the best-known essential oil world-wide might be eucalyptus oil, produced from the leaves of <i>Eucalyptus globulus</i>. </p>
<p>
Steam-distilled eucalyptus oil is used throughout Asia, Africa, Latin America and South America as a primary cleaning/disinfecting agent added to soaped mop and countertop cleaning solutions; it also possesses insect and limited vermin control properties. </p>
<p>
Note, however, there are hundreds of species of eucalyptus, and perhaps some dozens are used to various extents as sources of essential oils. Not only do the products of different species differ greatly in characteristics and effects, but also the products of the very same tree can vary grossly.<sup id="cite_ref-Thorpe1_1-1" class="reference"><a href="http://en.wikipedia.org/wiki/Essential_oils#cite_note-Thorpe1-1">[2]</a></sup></p>
