Reference Notes:
Individual herb information has sourced mainly from TCM Wiki and American Dragon for basic data and then updated manually with my own notes. Zhou, Xie and Yan (2011): Encyclopedia of Traditional Chinese Medicines, Vol. 5, has been used for entries not available from those sources with additional material searched for and filled in where available. Western herbs not appearing in the Chinese literature have used Ross (2010): Combining Western Herbs and Chinese Medicine: A Clinical Materia Medica, White Rabbit Institute of Healing and therapeutika.ch. Choices of which source to use or combine have been my own.
