Dulse (Palmaria palmata) is a type of red seaweed traditionally consumed in coastal regions of the North Atlantic, notably in Ireland, Scotland, and parts of Canada. Its use in herbal and folk medicine has included a range of applications, largely attributed to its rich mineral content, especially iodine, potassium, and magnesium. In traditional herbal practices, dulse has occasionally been referenced for its diuretic effects, which could theoretically support urinary system function by promoting urine production and helping to flush the urinary tract. However, these uses are not well documented in classical herbal texts or ethnobotanical literature, and references are generally anecdotal or based on the broader class of seaweeds rather than dulse specifically. There is very limited scientific research directly linking dulse to urinary system health or supporting its use for bladder or kidney conditions. Most modern evidence focuses on its nutritional value, antioxidant capacity, and potential metabolic benefits. Therefore, while there is some precedent for its use in supporting the urinary system within traditional frameworks, this support is minimal and not strongly substantiated. For direct urinary system benefits, dulse does not have robust traditional or scientific backing, and its use for this specific purpose is best considered as part of a broader, nutrient-rich diet rather than a targeted remedy.
