Sugar laminaria and palm-dissected kelp are used in food called “sea kale”. To replenish the daily dose of iodine (in regions with iodine deficiency in water), it is enough for a person to consume about 30-40 grams of fresh kelp daily [source not specified 86 days]. Laminaria is contraindicated in people with hypersensitivity to iodine. Laminaria is used for chronic constipation. Absorbing water and increasing in volume, it irritates the receptors of the intestinal mucosa and reflexively enhances intestinal motility.
