Ancient Romans and Greeks loved bay leaves. They believed that this simple herb was the source of happiness, clairvoyance and artistic inspiration. Whatever the case, it does act as an expectorant and is best taken in tea. To make the tea, tear a leaf (fresh or dried) and steep in 1 cup boiling water.
Another bronchitis remedy with bay leaf is to soak some leaves in hot water and apply as a poultice to the chest. Cover with a kitchen towel. As it cools, rewarm.
