Origin & History
Dulse (*Palmaria palmata*) is a red seaweed native to the cold coastal waters of the North Atlantic and Northern Pacific. Traditionally hand-harvested from rocky shorelines in regions like Ireland, Iceland, Canada, and East Asia, it is valued for its robust mineral profile, particularly iodine, and its rich umami flavor. Dulse serves as a significant functional food, supporting thyroid health, cardiovascular wellness, and digestive regularity.
“Dulse has been a dietary staple in Nordic and Celtic traditions for centuries, valued for both nourishment and its medicinal properties. Revered by monks, seafarers, and healers, it symbolized strength drawn from the sea. Its historical use as a sea herb underscores its long-standing role in traditional European coastal wellness practices.”Traditional Medicine
