Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Irish Moss (Chondrus crispus), a type of red seaweed, has been traditionally used in various cultures, especially in Ireland and the Caribbean, for its purported benefits to respiratory and sinus health. Folk remedies often cite Irish Moss as a mucilaginous herb that can soothe mucous membranes and support sinus comfort during colds or respiratory infections. The gelatinous nature of Irish Moss, due to its high carrageenan content, is believed to help coat and soothe irritated tissues in the throat and nasal passages, thus providing symptomatic relief. However, scientific studies specifically examining Irish Moss for sinus support are lacking. Most research on Irish Moss centers on its nutritional profile (vitamins and minerals) and the use of carrageenan as a food additive, rather than direct effects on the respiratory or sinus system. While its traditional use for soothing mucous membranes persists, there is currently insufficient clinical evidence to robustly validate these claims. Therefore, the justification for using Irish Moss for sinus support is primarily traditional, with a modest (2/5) evidence rating based on anecdotal and historical reports rather than scientific validation.
