Synopsis

Kelp refers to various species of large brown seaweed that grow in shallow coastal waters, particularly in temperate oceans. Some of the most commonly used kelp species in herbal medicine are Laminaria, Ascophyllum nodosum, and Ecklonia cava. Kelp is a rich source of iodine, minerals (especially calcium, magnesium, and iron), vitamins (such as vitamin A, C, and K), and polysaccharides, particularly fucoidan, which is believed to have anti-inflammatory, antiviral, and immune-boosting properties.

Kelp is primarily used for its thyroid-supporting properties due to its high iodine content, which helps maintain healthy thyroid function. It is also valued for its detoxifying effects, digestive health support, and antioxidant activity. Kelp is known to assist in weight management, partly because it contains fucoxanthin, a compound thought to aid in fat metabolism.

Kelp is consumed in various forms, including powdered supplements, capsules, tablets, teas, and as dried seaweed in foods like sushi. It is also added to cosmetics and skincare products due to its hydrating, anti-inflammatory, and nutrient-rich properties.

Historical Use
Kelp has been used for thousands of years in Asian cultures, particularly in China, Japan, and Korea, where it was an important part of the diet and medicinal tradition. In these cultures, kelp was commonly consumed for its health-promoting properties, particularly for thyroid health, digestion, and detoxification.

In Traditional Chinese Medicine (TCM), kelp is classified as salty and cold, and it is used to treat goiter, nodules, and thickening of tissues. Kelp is often included in formulas to clear heat, detoxify the body, and promote fluid metabolism.

In Europe, kelp was historically used as a fertilizer and sodium source, particularly in coastal areas. It wasn’t until the 20th century that kelp's health benefits, particularly its iodine content and role in supporting thyroid function, became widely recognized.

Today, kelp is a popular supplement in Western herbalism for thyroid support, detoxification, and overall mineral nourishment, especially for individuals who may be deficient in iodine or those seeking to improve digestive health and weight management. It also continues to be celebrated in Asian cuisine and health rituals for its nutrient density and restorative qualities.
