Sea moss—often referred to as Irish moss (Chondrus crispus)—is widely used across the UK and North America. However, Irie Sea Moss sources its seaweed from Saint Lucia, where the red algae species Eucheuma cottonii and Eucheuma spinosum thrive, cultivated for their potent carrageenan content.

What Exactly Is Sea Moss?
Sea Moss vs Irish Moss
Irish moss (Chondrus crispus) is a cool‑water, Atlantic red algae harvested along European and North American coasts—valued for kappa carrageenan. But Saint Lucian sea moss includes:
-
Eucheuma cottonii: Sun-dried "gold" sea moss, rich in iota carrageenan
-
Eucheuma spinosum: The purple-hued counterpart, also an iota carrageenan source
Both are steamed around Saint Lucia’s tropical waters and farmed on 'ropes', offering a softer texture suitable for gels.
A Rich Saint Lucian Heritage
Sea moss has long been part of Caribbean culture. In Saint Lucia, local communities have cultivated Eucheuma cottonii since the 1980s for carrageenan production and traditional healing . Today, it remains a crucial export with certifications ensured by the Ministry of Agriculture and is prized for nutritional richness.
