Mrs. Winslow's Soothing Syrup, 1888
Mrs. Winslow's Soothing Syrup was marketed as an indispensable aid to mothers, to help soothe babies' pain and discomfort while teething. The company used various media to promote their product. Containing one grain (65 mg.) of morphine per fluid ounce, it effectively quieted restless infants and small children. Sadly, many of these "soothing syrups" became known as "baby killers" due to the instances of infant death caused by these medicines.
