Cough Drop Day is observed annually on May 13 and celebrates the use of cough drops, which are small, medicated tablets designed to soothe sore or irritated throats. These lozenges, often candy-like in taste, have a history dating back to around 1000 B.C when ancient Egyptians created them using honey, herbs, citrus, and spices. In the 19th century, some physicians controversially added harmful ingredients like morphine and heroin to cough drop formulas, a practice that was later abandoned due to health risks. Today, cough drops are typically sweetened with agents like sugar and treacle, and various recipes can be found online featuring ingredients such as pears, cinnamon, and ginger. The day serves as an opportunity to recognize the evolution of cough drops and their role in providing relief from cold and flu symptoms.
