This is Eucalyptus 80/85 which refers to the eucalyptol content in the oil (80-85%). Other companies may supply an inferior quality known as 70/75. There are many hundreds of different types of Eucalyptus that contain high levels of eucalyptol but Globulus is the most popular. The Chinese production’s quality is good & very consistent. Eucalyptus is well-known for its clearing & anti-septic properties & is thus extremely useful during the winter months. It can be very effective in a steam inhalation to help congestion. Try adding 2 drops Eucalyptus 1 drop Roman Chamomile & 1 drop Lavender to a bowl of just-boiled water. Lean over the bowl (not too close) with a towel covering your head & inhale the vapours for a few minutes. Alternatively blend the same oils in two teaspoons of Sweet Almond oil & massage into the chest & back. Blended with Citronella or Cedarwood in an oil burner Eucalyptus can help maintain an insect-free BBQ! Alternatively try the lemon-scented Eucalyptus Citriodora as a very powerful natural insect-repellent.
