Invigorating and brisk, if Tea Tree won't wake you up in the morning, than nothing will. Its bright scent is known for the ability to clear sluggish sinuses, and in fact, Australian hospitals use Tea Tree in surgical ops for its properties. Tea Tree is also ideal in soothing serious eczema outbreaks.  From the Outback to your soap dish, Tea Tree is the work horse of the aromatherapy world.
