Parts Used – Root, aerial parts.
Soapwort’s main internal use is as an expectorant. Its strongly irritant action within the gut is thought to stimulate the cough reflex and increase the production of a more fluid mucus within the respiratory passages. Consequently, the soapwort is prescribed for the treatment of bronchitis, coughs, and some cases of asthma. Soapwort may be taken for other problems, including rheumatic and arthritic pain. A decoction of the root and, to a lesser extent, an infusion of the aerial parts of soapwort make soothing washes for eczema and other itchy skin conditions.
