Soak the carrageen and kelp overnight in 6 1/3 cups water.
The next day, roughly cut the kelp with scissors into small pieces. Place the kelp, carrageen and the water into a pot and bring to a boil. Simmer for about 30 minutes, and then transfer to a blender and whizz. Return the pulp to the pot and heat for 10 minutes more. Stir in the sand, salt and essential oil. Bottle in a glass jar.
Gently rub a handful of the scrub over the skin in the shower, using circular movements and paying particular attention to rough skin on the knees, feet and elbows. Rinse off well.
Do not use on the face. This is quite an abrasive exfoliator, so use no more than once a week.
The scrub will keep for 6 months in the refrigerator.
