Irish Moss Health Benefits

Irish moss is a form of algae first used in Ireland in the mid 19th century. Since then, its medicinal applications have increased more and more. The thallus of the alga has cartilaginous consistency (Latin Chondrus = cartilage) due to the high amount of mucilage it contains.

Healing properties and Indications

Besides 80% mucilage, the thallus is rich in iodine, provitamin D, and mineral salts. Its most important active component is the mucilage, to which Irish moss owes its emollient, expectorant, and laxative properties.

This alga is recommended for bronchitis and catarrhs since it promotes expectoration, eases coughs, and reduces the inflammation of the airways. It is also suitable for gastritis and intestinal inflammation caused by colitis or chronic constipation. Irish moss is widely used in the food industry because of its jellifying effects.
