Purple Sea Moss: One Colorful Food With 5 Epic Benefits

Shimmering purple. Some people call it a superfood. But what is Purple sea moss?

Purple sea moss is a red marine algae. These strands of red seaweed grow from “holdfasts.” 

Holdfasts are rocks below the surface of warmer bodies of water. They exist from the Atlantic coastline, the Caribbean and Europe.

Sea moss comes in a variety of colors. Where sea moss grows helps determine the color it has.  Red algae that grows closer to the surface of the water has a lighter greenish yellow to gold color.

Purple sea moss is also known as Irish moss or Carrageen moss.

Deep divers retrieve Jamaican purple sea moss from the Caribbean seabed. So purple Jamaican sea moss is wild, organic sea moss.

Cleaning: Place the moss in a large bowl. Pour enough water to cover the seaweed.

Gentle rub to release debris that may be on the seaweed. Pour off the water and repeat the process. 

Note. Sea moss harvested from the ocean may have a high sodium content.

So I usually soak it for about 30 minutes and throw away the first water. Then I start the hydrating process.

Rehydrating: To rehydrate seaweed add two or three cups of water to fully cover the moss cover and let sit for approximately 24 hours.

Wildcrafted organic sea moss will have an ocean-like smell when you rehydrate it.
