Indications : Blood root finds its main use in the treatment of bronchitis. Whilst the stimulating properties show in its power as an emetic and expectorant, it demonstrates a relaxing action on the bronchial muscles. It thus has a role in the treatment of asthma, croup and also laryngitis. However, by far the most important contribution Sanguinaria has to make is in chronic congestive conditions of the lungs including chronic bronchitis, emphysema and bronchiectasis. It acts as a stimulant in cases of deficient peripheral circulation. It may be used as a snuff in the treatment of nasal polypi.
Ellingwood considered it specific for harsh, dry cough with relaxed tissues of the pharynx, larynx and bronchi, with a sense of constriction and constant irritation and uneasiness or tickling of the throat. In addition he recommends it for the following patholgies : congestion of the lungs, bronchial coughs, stridulous laryngitis, membranous croup; externally for otitis media, indolent ulcerative conditions, nasal catarrh, anal fissure, epithelioma, lupus.
Kings Dispensatory describes this herb as being specifically indicated in the following symptom picture: Sensation of burning and itching of mucous membrane, especially of fauces, pharynx, Eustachian tubes and ears; less frequently of larynx, trachea, and bronchia, occasionally of stomach and rectum, and rarely of vagina and urethra. The mucous membrane looks red and irritable. Sometimes the redness will be of the end of the nose. Nervousness, redness of nose, with acrid discharge, burning and constriction in fauces of pharynx, with irritative cough and difficult respiration.
