Bladderwrack

Bladderwrack is also known as Black-tang, Cutweed, Kelpwave, Quercus marina, Seawrack, and Bladder focus. It is seaweed that grows off the Atlantic and Pacific coasts of the US, and is equally abundant off the Atlantic coast of Europe. It can also be found in the North and Baltic seas as well. Bladderwrack's name is derived from small air bladders that arise from the body of the seaweed, which help to keep it afloat. The total length of the seaweed can be greater than 3 feet. It is a light olive green color when alive and will turn a medium brown when dead and dried.


Much of the information about Bladderwrack is based on its historical usage, and to date, very few research studies have been carried out. Historically, it has been used for conditions of the thyroid, rheumatic conditions, as a laxative, and demulcent. Because of its purported effects upon the thyroid gland, it was also used as an aid for weight loss.


There are three main constituents or ingredients in Bladderwrack.

  • The first is iodine. Iodine found in bladderwrack is responsible for thyroid stimulating activity. The seaweed can have variable amounts of iodine depending on the location it was grown in.
  • The second well-known constituent is alginic acid. This is a fibrous material. Because of the alginic acid component, Bladderwrack is considered as a laxative and lipid-lowering herb.
  • The third constituent is fucoidan. It is a polysaccharide and is the most widely studied constituent of Bladderwrack. Fucoidan is considered an anti-oxidant, anti-inflammatory agent, and may provide for some anti-coagulant activities.
