Christopher Hobbs:
“Irish moss is used to treat bronchitis and coughs, as it is both an expectorant and demulcent herb. Its soothing properties also make it useful for gastritis, ulcers, and kidney and bladder ailments. Irish moss is often included in skin lotions as a skin softening agent.
Irish Moss has a taste of SALTY and a temperature of COOL.”
Historical Uses
Historically, Irish moss has been used as a folk remedy for respiratory ailments (e.g., coughs, bronchitis), digestive disorders, and to strengthen immune function. Its high mucilage content has made it a soothing demulcent for irritated tissues.
Modern Clinical Uses by Herbalists and Naturopaths
Today, herbalists and naturopaths use Irish moss for its nutrient-rich profile (vitamins, minerals, and polysaccharides) and its soothing effects on the mucous membranes of the respiratory and digestive tracts. It’s also popular in skincare formulations for its moisturizing properties. Many believe it supports thyroid health, possibly due to its iodine content, though iodine levels in Irish moss vary widely.
Chemistry and Pharmacology
Irish moss contains carrageenan, a polysaccharide with gelling, thickening, and stabilizing properties, which is widely used in the food and pharmaceutical industries. Carrageenan has anti-inflammatory, antiviral, and antioxidant effects, though some forms of processed carrageenan have raised safety concerns. Other compounds include vitamins A, E, F, and K, as well as minerals like potassium, calcium, and magnesium.
Clinical Trials
Research on Irish moss specifically is limited, though studies on carrageenan, its primary active compound, have shown mixed results. Carrageenan has demonstrated antiviral and anti-inflammatory effects in vitro, though animal and human studies on its health benefits and potential risks are limited. Further clinical research is needed to establish efficacy and safety for specific therapeutic applications.
Summary
Irish moss has a rich history as a traditional remedy and remains popular in natural health for its potential nutritional and medicinal benefits. While it is nutrient-dense and offers various health benefits, its main active compound, carrageenan, has raised some safety concerns. Therefore, moderate use and professional guidance are recommended, particularly for those with underlying health conditions.

Cautions
Irish moss is generally considered safe when consumed in moderate amounts. However, processed carrageenan may pose digestive or inflammatory issues, and excessive intake could lead to thyroid or electrolyte imbalances due to its high iodine and mineral content. Individuals with thyroid disorders or iodine sensitivity should consult a healthcare professional before use. Exact dosages are not well-established due to the lack of standardized guidelines.
