Fucus vesiculosus is the botanical name for kelp, the deep green oceanic plant probably best known as seaweed, cutweed and also occasionally referred to as bladderwrack.
Although kelp is only one variety of seaweed, it is the most common and valued for its rich nutritional value. The Japanese have been harvesting vegetables from the ocean for centuries and not surprisingly, kelp forms an essential part of their diet.

Traditionally, kelp oil was used for relief from arthritis, for cellulite and weight loss and in skin softening lotions, but arguably its greatest contribution is its high iodine content, an important mineral for the functioning of the thyroid gland, regulating metabolism and weight.

What is kelp used for?
Hyperthyroidism and general thyroid health - Japanese studies have shown that the high iodine value in kelp assists with healthy thyroid function and is therefore an effective treatment for hyperthyroidism.
Research has also shown that kelp is a good antioxidant, diuretic and endocrine tonic and cultural studies relating to the dietary consumption of kelp have shown it to lower the rate of breast cancer, heart disease, rheumatism, arthritis and infectious diseases.
Kelp also provides nutritional support to the nervous system and heart in the form of iodine, vitamins, minerals and cell salts.
Dosage
Kelp may be taken in tablet form as a dietary supplement or as a tea infusion.
To make kelp tea, add 2-3 teaspoonfuls of the dried herb in a cup of boiling water, and leave to steep for 10 minutes. Drink three times a day.
Powdered kelp can also be added to most dishes or sprinkled over soups and salads.
Cautions
