Western herbal medicine is the most widely used form of herbal medicine in Australia although Ayurvedic and Chinese herbal medicines are becoming better known. The agricultural production and manufacture of locally grown herbs is, with some exceptions, relatively underdeveloped, as is the research and development of indigenous flora. However, the use of herbal medicine is increasingly becoming mainstream with retail sales of herbal products in Australia estimated to be A$200 million. Concurrent with the increase in popularity of herbal medicine with health consumers have come advances in herbal medicine education and regulation. Although small by European standards, research into herbal medicines is increasing, mainly through industry and University-based initiatives.
