Sea salt is sea water salt that has been extracted from the sea water. It is extensively used for cooking, baking, cosmetics, and even for preserving food and as a seasoning on foods. In fact, it is also known as black salt or solar salt. Like mined gemstone salt, production of sea salt dates back to prehistoric times.
Salt deposits are formed at sea floor, where sun evaporates and refreezes. The exposed rock salt gradually comes in contact with air until minerals contained within the salt come to the surface. As a result, there is a salt concentration, which alters its chemical and mineral properties. The salt mineral content changes from a basic salt (NaCl) to an earthy mineral composition, including magnesium, calcium, and iron, and traces of manganese, zinc, copper, and sodium.
Most sea salts produced today are derived from evaporated seawater. During evaporation, all salt residues are lost, along with any dissolved molecules that were bound with seawater during the initial extraction process. Evaporated salt is collected at the sea bed and transported to salt mines, where it is processed into salt.
The mineral content of sea salts depends on the ratio of chloride and bromide contained in the seawater, and on the amount of organic materials that have been dissolved. Chloride, often the dominating salt mineral component, is present in relatively higher amounts in seawater than in groundwater. Bromide is absent, and so the salt’s chemical composition is slightly less than that of chloride. Organic materials may play a role in the chemical composition of salt by reducing the concentration of other dissolved substances. So, in the same river where commercial fishing has occurred, for instance, minerals like gypsum and red rock can dominate the chemical composition of salt and contribute to its economic value as a product.
Sea salt benefits humans in a number of ways, although the most obvious benefit is as a food source. Fresh sea salt contains a variety of trace minerals that are beneficial to human health. For example, magnesium helps in the development of nerve cells. Bacteria that are growing in water contain magnesium chloride, and sea salts are good sources of this trace mineral. Ionized salt can help reduce the negative effects of ionizing radiation on the body, and thus may be used in medical settings.
Some sea salts contain a range of naturally healing ingredients, including potassium and magnesium chloride, which are known to provide a range of therapeutic effects. A natural healing salt bath may even promote healing of dry skin or cracked heels, since it increases blood circulation and enhances the production of natural healing compounds like collagen. These properties make sea salts a valuable ingredient in natural healing therapies.
Many people also choose to use the benefits of natural healing salts in their bath products and cosmetic products, as well as in recipes. Epsom salts have been used for centuries as an effective moisturizer, particularly for aging skin. Sea salt soaps and bath gels often contain Epsom salts as an ingredient. Natural sea salt soaps are particularly beneficial for use in the treatment of burns, eczema, and psoriasis. In fact, sea salt soaps and bath gels have become very popular as ingredients in natural healing therapies due to their success in healing these conditions.
Sea salt has even been used to create a type of jewelry. Called “salmonette” by French women, the item was originally created by decorating sea salt clasps with crystals of lavender and jasmine. The clasps were then woven together to form cord-like strips, and these pieces were worn around the wrist. The ancient Greeks and Egyptians used sea salt in jewelry as well, along with other natural ingredients. Today, you can find a variety of jewelry items containing sea salt and other minerals, such as bracelets, earrings, necklaces, and rings.
