Fucus nodosus is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world.
In Scotland and Norway, up until the mid-19th century, several seaweed species from Fucus and other genera were harvested, dried, burned to ash, and further processed to become “kelp”, which was a type of soda ash that was less costly in Britain than the barilla imported from Spain. It has analkali content of about 2.5%–5% that was mainly sodium carbonate (Na2CO3); alkali is essential to soapmaking, glassmaking, and other industries. The seaweed was also used as fertilizer for crop land in the same areas in which it was harvested.The purest barilla had a sodium carbonate concentration of about 30%.
In 2005, it was announced that bacteria grown on Fucus have the ability to attack and kill the MRSA superbacterium
Several types of seaweed, including Fucus vesiculosus, show potential for being able to prevent and treat cancer, based on animal and laboratory studies, according to the NIH. Fucus vesiculosus may suppress the growth of cancer cells.
Blood Sugar Reduction
Fucus vesiculosus extract may reduce blood glucose levels, making it useful for treating people with diabetes. This potential use is only based on animal research, however, according to the NIH, and reliable human studies are lacking.
Fucus vesiculosus contains fucans and fucoidans, components which show anticoagulant, or blood-thinning, properties in laboratory research, according to the NIH. Additionally, fucosterols in this substance reduce plasma cholesterol levels, as explained by the MSKCC. The plant may lower high blood pressure because it inhibits angiotensin-I-converting enzyme. Medications with this effect, called ACE inhibitors, are commonly used to treat high blood pressure.
A study published in the January/February 2002 issue of the Journal of Cosmetic Science determined that Fucus vesiculosus extract possesses anti-aging properties and should be useful as a cosmetic ingredient. The study found that a gel containing 1 percent Fucus vesiculosus extract applied to cheek skin twice daily for five weeks decreased skin thickness and improved elasticity when compared with control substances. The authors note that cheek skin thickness normally increases with age, whereas elasticity decreases.
Special Precautions & Warnings:
Pregnancy and breast-feeding: Not enough is known about the use of Fucus nodosus during pregnancy and breast-feeding. Stay on the safe side and avoid use.
