This large variety of seaweed has seen use in most cultures and regions throughout the world. In some European regions, it was quite commonly used in soap and glass production, with Kelp being burned to create the soda ash that was used in such production methods. In the Pacific, Kelp is quite important to Japanese cuisine, and is often used to flavor broths and stews, as well as a stand-alone vegetable or a garnish. It can also be found in Japan as a main ingredient to a wide range of snack products. Imbued with high concentrations of iodine, Kelp was also often used in medieval times to treat the growth of goiters, which can develop from the thyroid gland when a person is experiencing a lack of iodine in their diet. More modernly, Kelp can be found in a much wider array of products. In some circles it is used as a favored salt substitute, and is used as an addition to cosmetic baths where it is said to tone, hydrate and help clear skin. It is also quite frequently found in a wide array of health food supplements, as it is a rich source of natural vitamins and minerals. Indeed, Kelp has been found to contain Magnesium, Calcium, Phosphorus, Iron, Potassium, 12 vitamins (including A, B1, B2, C, D and E), 21 amino acids, 60 minerals and true elements, and as studies have revealed it is particularly rich in Iodine and Vitamin E.
