Chop the garlic into small pieces. Place the garlic and mullein flowers in a small glass jar with a lid. Cover the mullein flowers with olive oil and allow to set in the sun for several days, or heat over very low heat for 4 hours. If you are using fresh mullein flowers, cover your jar with cheesecloth rather than a lid to allow moisture to escape. Strain the oil through cheesecloth and store your oil in a small dropper bottle in the refrigerator.
Warm the oil to body temperature by placing the bottle of oil in a glass of hot water for a few minutes. Insert 2-3 drops in the affected ear 2-3 times per day.
If there is fluid oozing from the ear or any chance that the ear drum is perforated do not use the ear oil and consult your doctor.
