While chicken soup is now known as a common food to eat when you have a cold or the flu, it used to be known for its aphrodisiac qualities. In the Middle Ages, chicken soup was touted as an aphrodisiac for individuals. An aphrodisiac is something that increases someone’s sex drive. At the time, chicken broth was known to both cure illnesses and improve people's moods. Only the curing illness portion has withstood the test of time.
