Sometime called Thieves' Blend or Bandit's Blend, Marseille's Remedy can either be used to the clear the air (literally) of various types of pathogens and to help stave off various types of respiratory infections with its vapors when emitted by an aromatherapy diffuser.
It can also help clear the skin of various types of inflammations (such as acne or boils) or infections when used in a diluted form (whether in the pre-diluted balm or as part of a solution or do-it-yourself personal care product). It's also used to help relieve various aches and pains, including digestive discomforts; or even as a surface cleaner.
Syzygium aromaticum (Clove bud oil* – India), Citrus limon (Lemon oil* – Italy), Cinnamomum verum (True Cinnamon bark oil* – Sri Lanka), Eucalyptus polybractea (Blue Mallee Eucalyptus oil* – Australia), Rosmarinus officinalis (Rosemary oil* – Spain).
To help fight sickness and clear the air of pathogens, use perhaps five to ten drops in an aromatherapy diffuser or nebulizer as you would with other essential oils, and breathe some of the vapors.
