Irish moss is a reddish-brown seaweed growing to 10 inches, with a flat, forked plant body and fan-shaped outline. Found on the Atlantic coasts of Europe and North America, it grows just below the waterline, attached to rocks and stones. In summer in North America and in autumn in Ireland, it is pulled up by hand or with a rake at low tide and dried in the sun. This seaweed is used extensively in the food and pharmaceutical industries as an emulsifying and binding agent, appearing in products such as toothpastes. Its polysaccharides become jelly-like and demulcent when immersed in water, making it valuable both as a food ingredient and medicinal herb.

Lungwort is a perennial herb growing to 1 foot with broad oval basal leaves, smaller upper leaves mottled with white spots, and clusters of pink-purple flowers.

This folk belief, while not scientifically founded, turned out to have merit - the herb is indeed valuable for respiratory conditions.
