Irish Sea Moss (Chondrus crispus), also known as carrageen moss, is a type of red algae native to the Atlantic coasts of Europe and North America. It has been used for centuries in traditional Irish and Caribbean cuisine and herbal medicine for its potential health benefits.

Irish Sea Moss is rich in essential minerals, including iodine, calcium, magnesium, and potassium, as well as vitamins and antioxidants. It is known for its mucilaginous (gel-like) texture when hydrated, which makes it a popular ingredient in vegan cooking and plant-based desserts as a natural thickener.

In herbal medicine, Irish Sea Moss is believed to support thyroid function due to its iodine content, promote digestive health, and support overall immune function. It is also valued for its potential skin benefits when used in topical applications.

Irish Sea Moss can be used in various culinary preparations, such as smoothies, soups, stews, sauces, and desserts. It is often soaked and blended into a gel-like consistency to add thickness and nutritional value to recipes.
