"This book is neither a set of herbal monographs nor a cursory discussion of research mixed with rhetoric; instead it offers concrete and insightful discussion of research methodology in traditional herbal medicine. While it does not replace reference books containing complete scientific monographs on specific herbal medicines, it is complementary, providing the research framework required to develop scientifically sound, quality products. For this important role, it is highly recommended." (Doody's, 5 August 2011)
