The common name for Fucus vesiculosus is bladder wrack. It is grown on the coastline of colder regions including the northwestern United States and northern Europe. The plant has receptacles that are usually swollen at the ends, which has everything the plant needs to reproduce (both eggs and sperms). When it’s about to die, the seaweed’s swollen ends will burst. This way the plant manages to reproduce itself.
The plant has a thick skin that secretes a sticky substance that helps keep it moist. It contains fucoidan and myostatin, which have been reported to have varying health benefits such as being an anti-coagulant (blood thinning and anti-clotting), anti-inflammatory, and anti-viral. There will be more about fucoidan and it benefits in the section about the brown sea plant Ascophyllum nodosum.
Fucus vesicuiosus also contains alginate. Besides helping to excrete toxins from the body, alginate may also positively affect the immune system T-cells and support the endocrine system (or hormonesystem) in the body. Lastly, alginate from Fucus has been used to help control gastroesophageal reflux disease (also known as GERD). GERD is a type of chronic heartburn. Statistics show that more than 60 million Americans experience heartburn once a month. The alginate from Eucus may help control the reflux problem and reduce the acidity content of the stomach.
