Irish Moss (Chondrus crispus) is a sea weed used for lung diseases associated with dryness and/or wasting. It is also used topically or internally for ulcers and sores. Its most important ingredient is a pectin called carrageenan that is similar to agar-agar. Its mucilage content makes this plant useful in any treatment of the skin or the mucous membranes. It absorbs toxins from the bowel. Due to its high iodine content, Irish Moss supplies iodine through the intestinal tract in the interplay of fluids between the intestinal and bloodstream by way of the intestinal villi.
