The wild Frankincense tree is considered sacred by many ancient cultures. It is believed that the Frankincense tree was a gift from God to humankind to aid us ascend to the higher realms. It must never be cultivated by mankind; it must be left to the care of mother nature.
On the respiratory system it works very much in the same way as eucalyptus, by encouraging the body to clear out pathogens and mucus, so when the two are blended they become more effective. Frankincense calms breathings as well as calming the mind, balancing the emotions whilst being uplifting; it is therefore a much-used oil for aiding mediation.
