Pearl Barley (薏仁 yìrén/意洣 yìmí)
Pleasant to the palate, it strengthens the spleen, helps relieve rheumatoid arthritis, combats diarrhoea, lung abscesses, lobar pneumonia and appendicitis, and, because it has a tendency to convert moisture within the body, is a great help to all those who have difficulty in urination.
