The use of Tea Tree Oils has a long history in Australian traditional medicine. Today, Tea Tree Oils are manufactured for a variety of purposes, including for the use in cosmetics and health products. The Australian Tea Tree Industry is a major provider of Tea Tree Oils, providing high quality standard essential oils to countries worldwide.
Apart from its traditional use, many new applications have been developed and tested. The research in the last decade alone has increased substantially, adding hundreds of studies to the current literature. Since the last comprehensive review was conducted in 2006/2007, an update is urgently needed in order to determine the status quo, and strategically conceptualize future research initiatives and product developments. It is further necessary to update consumers and stakeholders about the current scientific evidence to ensure effective and safe application of Tea Tree Oil products.
