Botanical name :Fucus vesiculosus
Family: Fucaceae
Genus: Fucus
Species: F. vesiculosus
Kingdom: Chromalveolata
Phylum: Heterokontophyta
Class: Phaeophyceae
Order: Fucales
Common names: black tang, rockweed, bladder fucus, sea oak, black tany, cut weed, dyers fucus, red fucus, and rock wrack,Kelp/Bladderwrack , Fucus, Seaweed, dried
Habitat ;Fucus vesiculosus is the most common algae on the shores of the British Isles. It has been recorded from the Atlantic shores of Europe, Northern Russia, the Baltic Sea, Greenland, Azores, Canary Islands, Morocco and Madeira. It is also found on the Atlantic coast of North America from Ellesmere Island, Hudson Bay to North Carolina
Description:
The fronds of Fucus vesiculosus have a prominent midrib and almost spherical air bladders which are usually paired but may be absent in young plants. The margin is smooth and the frond is dichotomously branched. It is sometimes confused with Fucus spiralis with which it hybridises

Plants of F. vesiculosus are dioecious. Gametes are generally released into the seawater under calm conditions and the eggs are fertilised externally to produce a zygote. Eggs are fertilised shortly after being released from the receptacle. A study on the coast of Maine showed that there was 100% fertilisation at both exposed and sheltered sites. Continuously submerged populations in the Baltic Sea are very responsive to turbulent conditions. High fertilisation success is achieved because the gametes are only released when water velocities are low
chemical Constituents:
Primary chemical constituents of this plant include mucilage, algin, mannitol, beta-carotene, zeaxanthin, iodine, bromine, potassium, volatile oils, and many other minerals.
Medicinal Uses:
Properties: * Analgesic * Antiscorbutic * Appetite Depressant/Obesity * Laxative

Kelp, dried seaweed Fucus vesiculosis, was the original source of iodine, being discovered as such by Courtois in 1812. Iodine does not occur in nature in the uncombined condition but is widely, though sparingly, distributed in the form of iodides and iodates, chiefly of sodium and potassium, in seawater, some seaweeds, and various mineral and medicinal springs. Kelp is an important part of the diet in Japan, Norway, and Scotland. For vegans (vegetarians who eat no animal products at all), it supplies vitamin B12, otherwise found almost exclusively in animal products, and is a concentrated source of minerals, including iodine, potassium, magnesium, calcium, and iron. As a source of iodine, it assists in the production of of thyroid hormones, which are necessary for maintaining healthy metabolism in all cells of the body. The brown algae known as bladderwrack is a particularly common source of kelp.
The main use of bladder wrack (and other types of seaweed) in herbal medicine is as a source of iodine, an essential nutrient for the thyroid gland. Bladder wrack has been used in the treatment of underactive thyroid glands (hypothyroidism) and goitre.
Bladder wrack has been shown to help women with abnormal menstrual cycling patterns and menstrual-related disease histories. Doses of 700 to 1400 mg/day were found to increase the menstrual cycle lengths, decrease the days of menstruation per cycle, and decrease the serum levels of 17B-estradiol while was later carried out and showed similar effects.
Safety precautions:
Bladderwrack may contains significant amounts of iodine, which could cause an allergic reaction in sensitive people
