Popular blend used by many for "guarding your health". Great blend to use preventatively during cold and flu season in an inhaler, or diffuser. I like having a blend along when you get seated next to someone that is sick on a plane or traveling. Takes the ache out of sore throats and swollen necks, add to hot baths, apply of soles of feet. Lemon, cinnamon, clove, eucalyptus, tea tree, rosemary.
