Horehound (Marrubium peregrinum)
You may have had old-fashioned horehound candy as a child, the taste of which is elusive (some say it is like root beer, others like licorice, still others, like anise or even tea -- but there is always a trace of its signature bitterness).
Horehound affects the respiratory and digestive systems.*
