Tea tree oil
Tea tree oil does not come from a tree used to make tea. The tea we drink comes from a completely different plant.
Tea tree oil comes from the leaves of a tree native to Australia which has been used by the aboriginal people as a traditional medicine.
Tea tree oil is a broad-spectrum anti-microbial and it’s found in many over the counter products.
Product uses include treating acne, athletes foot, dandruff, lice, nail fungus, cuts, and insect bites.
A look at the clinical studies helps understand where Teatree oil may have the most promising effectiveness. Note: Teatree oil should never be swallowed.
For acne, the effectiveness of tea tree oil was compared to benzoyl peroxide which is a common ingredient in over-the-counter acne products.
Both were effective at reducing the number of acne lesions, with benzoyl peroxide being more effective. But, teatree oil showed less scaling, dryness, and itchiness then benzoyl peroxide.
For people with mild to moderate dandruff, Teatree oil improved several dandruff measurement scores and the related itchiness.
