Notable Constituents:
- Allantoin
0.6-4.7% (Staiger, 2012) of the root is comprised of allantoin which is a product of the oxidation of uric acid and present in the urine of most mammals except higher primates. It has healing, soothing, and anti-irritating properties; helps to heal wounds and skin irritations and stimulates the growth of healthy tissue. It is often found in anti-acne products, sun care products, and clarifying lotions as well as toothpaste, mouthwash, and other oral hygiene products, shampoos, lipsticks, cosmetic lotions and creams, and other cosmetic and pharmaceutical products where it is usually extracted from cow urine or the comfrey plant.

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, and A+ Medical Encyclopaedia have 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.
