A strong blend of eucalyptus, rosemary, clove, and tea tree oil.
Essential oil inhalers are quick ways to get aromatherapy benefits without diffusing. The oils are placed on the cotton wick inside the inhaler. The fastest way to get a response from an oil is via inhalation. The oils will last on average 2-3 months or more depending on use. My current inhaler that I use about once a day is still strong after 6 months.
