Eucalyptus works as an expectorant and helps cleanse your body of toxins and harmful microorganisms that can make you feel sick. One of the most effective ways to utilize eucalyptus for colds is to drop several drops of the essential oil into your diffuser before going to sleep so you can take advantage of the healing benefits all night long.
A few drops eucalyptus oil with some coconut or olive oil gives your hair a nice moisturizing pick-me-up. This is especially great to ward off dandruff and an itchy scalp. Also, eucalyptus is used as a natural remedy for lice in replacement of chemical treatments.
