Notable Constituents:
- Ursodiol
Also known as ursodeoxycholic acid (UDCA) which prevents the synthesis and absorption of cholesterol and can lead to the dissolution of gallstones. Fortunately it is easily synthesised
- Bile Acids
Steroid acids and salts that are conjugated with taurine of glycine to become bile salts that play an important role in the digestion and absorption of fat.
- Taurine
An amino sulfonic acid derived from methionine and cysteine metabolism abundant in many animal and fish organs and a major constituent of bile. It has many biological roles, including conjugation of bile acids, antioxidation, osmoregulation, membrane stabilisation, and modulation of calcium signalling. It is essential for cardiovascular function, and development and function of skeletal muscle, the retina, and the central nervous system. It is used as an oral supplement in the treatment of disorders such as cystic fibrosis and hypertension and widely used in energy drinks, cosmetics and nutritional supplements.
There are also numerous other constituents which may encourage wound healing and resistance to injury from extreme conditions experienced during hibernation which are being researched by Paul Iaizzo and investigated for synthetic alternatives (e.g.
Iaizzo et al, 2012,
Hoffmann, 2019 and
Matsangou, 2019).

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.
