Because of its high mucilage content, it is a good remedy for chest conditions, especially that of chronic bronchitis. It combines well with such herbs as coltsfoot as a treatment for chronic coughs (including whooping cough), and can be taken for asthma. It has long been used as a treatment for bloody phlegm arising from tubercular infections.
Lungwort is also used as a treatment for sore throat and congestion.
