V-VAX EUCALYPTUS OIL SPRAY organic oil comes from the central New South Wales region of Australia, a semi-arid area which is home to the richest cineole-bearing Polybractea (blue mallee) variety of eucalyptus. It is extracted using a chemical-free, double distillation process to ensure the highest level of purity. The result is a colorless, mobile liquid with heavenly wood-scented undertones. It blends well with thyme, rosemary, lavender, marjoram, pine, cedar wood and lemon. To qualify as an active agent, eucalyptus oil must contain at least 70% cineole (a major component of camphor-scented essential oils found in eucalyptus leaves). V-VAX Eucalyptus Oil contains 85% to 90% cineole.
