Bladderwrack (Fucus Vesiculosus)

Bladderwrack Benefits

Bladderwrack is a form of kelp that has been used medicinally for centuries. The main use of the herb has been for the stimulation of the thyroid gland as a treatment for obesity and cellulite. The high iodine content of the herb stimulates thyroid function which boosts metabolism.

It has a reputation in the relief of rheumatism and rheumatoid arthritis and may be used both internally and as an external application for inflamed joints. The main phytotherapeutic use of Fucus is during debility and convalescence, and also to remineralise the body.

Fucus also appears to assist in the problem of lipid balance associated with obesity, and where obesity is associated with thyroid dysfunction, this herb may help to reduce excess weight.

Bladderwrack is rich in iodine, calcium, magnesium, potassium, sodium, sulfur, silicon and iron and high in some B-complex vitamins. It contains moderate amounts of phosphorus, selenium, manganese and zinc and small amounts of vitamins A, C, E and G. It also contains anti-sterility vitamin S as well as vitamin K. It is rich in algin and mannitol, carotene and zeaxantin with traces of bromine.

for comments about bladderwrack not working,,,FYI!!! Those that are not O (+) or (-) blood type it is not beneficial for weight loss...get the book "EAT RIGHT FOR YOUR BLOOD TYPE" BY DR. PETE J. D'ADAMO...Extremely interesting and if you know your blood type you will relate to it... go to pg 90, herb recommended for O plan, look at last sentence under BLADDERWRACK. (NOTE***HOWEVER, THAT ALTHOUGH BLADDERWRACK HAS A TIME -HONORED REPUTATION AS AN AID IN WEIGHT LOSS FOR TYPE 0'S, IT DOES NOT WORK THAT WAY FOR OTHER BLOOD TYPES.)....... MEANING IF YOU ARE NOT O BLOOD TYPE.... IF YOU FALL INTO CATEGORY A, AB. OR B... DO NOT TAKE IT WILL NOT BENEFIT YOU... PLEASE RESEARCH BEFORE TAKING HERBS ETC... KNOW YOUR FACTS... GOOD LUCK :)
