This box contains enough dried serrated wrack (Fucus serratus) for a seaweed bath in a normal size bathtub. The seaweed has been traditionally harvested by hand in the waters outside Varberg on the west coast of Sweden and then dried naturally. Seaweed has long been used in SPA baths and is believed to stimulate blood circulation, relax stiff muscles and relieve aches and pains, irritation of the skin and sunburn. Sea weed adds nourishing minerals and has detoxing properties. It is known to calm skin irritations and to stimulate circulation.
