This oil contains a soothing blend of penetrating oils. Garlic bulb oil, St. John's Wort flowers and mullein infused into virgin olive oil and tea tree essential oil for their antibacterial properties. Gently warm the oil, and place 2-3 drops in affected ear and plug it with a cotton ball. Ear drops may be applied 2 or more times a day, It may also be helpful to apply a warm compress. I have used this remedy on my grandchildren with fast results. It should not be used if water is present in the ear. It can safely be massaged behind and under the ear.
