9 Best Uses for Tea Tree Oil

For more than 80 years, tea tree oil has been steam distilled from the leaves of the native Australian plant Melaleuca alternifolia. The benefits of the melaleuca plant have long been praised by Indigenous Australian peoples.

Traditional uses included crushing the leaves, inhaling them to treat colds and coughs, applying medicinal preparations to wounds, and soaking the leaves to create infusions for sore throats and skin ailments. Today, leaves are harvested from melaleuca plantations in Australia and then steam distilled, creating an aromatic essential oil with well-documented healing properties.

More than 300 scientific articles provide evidence of the antiseptic, antibacterial, antifungal, antiviral, and anti-inflammatory properties of tea tree oil. It’s a treatment for everything from cold sores to athlete’s foot.

Commonly found in cosmetics, as well as skin and hair products, tea tree oil is also known for being the active ingredient in many over-the-counter acne treatments. Many supermarkets and natural health retailers carry the oil at 100 percent strength.

Save space, time, and money by making your own eco-friendly remedies and cleaning solutions from tea tree oil.
