Tea Tree has a warm, spicy, medicinal and pungent aroma. It is a very powerful immune stimulant, helping fight infections and promote clear skin. A natural antiseptic, bactericide, fungicide and anti-viral with anesthetic qualities, it is still gentle enough for everyday usage. Unlike most other antiseptic preparations, it can be used without causing an imbalance of the natural bacterial flora on the skin. It makes a good oil to diffuse during cold and flu season to help purify the air.
