Polysaccharide found in brown seaweeds whose sodium salt is the main active ingredient in antacids and used as an emulsifier, thickener, and stabiliser in food and cosmetic industries. Calcium alginate is used in wound dressing to promote healing.
Notes:
Actions and indications taken from Ross (2010) Combining Western Herbs and Chinese Medicine: A Materia Medica. He also notes that while most seaweeds in China are considered Cold in temperature, Bladderwrack is used in the west for hypothyroidism with sensations of cold. He therefore classifies its temperature as neutral and suggests it is appropriate for Yang deficient types of hypothyroidism.

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.
