This oil comes from the leaves of a tree that grows in Australia. Because it can kill some types of bacteria and fungus, people have used it as a home remedy for many years.
When rubbed into the skin twice a day, tea tree oil can reduce the itching, scaling, swelling, and burning of athlete’s foot. But it may take up to a month to see progress and it doesn’t work for everyone.
Tea tree oil can cause a skin rash or trigger allergies. So talk with your doctor before you try it. She can suggest a tea tree product for you to try, or explain how to dilute the oil to avoid side effects.
Never take tea tree oil by mouth since it can be toxic.
