The eucalyptus tree is indigenous Australia and tasmania. They are found in most mild climates in California as well; which is where I grew up. I have really great memories of driving though the rolling hills just south of San Fransisco along the coast line, taking in that fresh clean scent. As a massage therapist I freqently used Eucalyptus oil to concoct theraputic mixes. It is one of the most useful of all the essential oils. These are the most common uses: Air Disinfectant Asthma Bronchitis Burns Cuts Decongestant Flu Headaches Insect Repellant Muscle Aches Rheumatism Sinusitis Skin Ulcers Urinary Infections Wounds
