I have tried this ancient Ayurvedic remedy for ear-aches not just on myself but for my 10 year old daughter and it has worked....everytime!
Mix 3-4 drops of T-tree oil in 1/4 cup of sesame oil, mix well and keep aside in a small clean bottle for storage/future use. Add 2-4 drops of this oil mixture in the ear by a dropper... The pain and infection will be gone in a few hours. These two oils in combination form a natural antifungal, antibacterial and antiseptic compound.... no need to go to a doctor for antibiotics.
