Who created National Mustard Day, and what is its history?
National Mustard Day was officially created in 1991 by the founder of the National Mustard Museum, located in Mount Horeb, Wisconsin, at the time. The event later moved to Downtown Middleton in 2010, where it continues to draw thousands of mustard fans each year. While the official holiday began in the 1990s, mustard’s legacy dates back thousands of years. Ancient Egyptians used mustard seeds for medicinal and culinary purposes.
Greeks and Romans adopted similar practices, and by the 9th century, French monasteries were producing and selling mustard widely. The word “mustard” is derived from “mosto,” an unfermented grape juice that was traditionally mixed with ground seeds. In the 13th century, Pope John XXII even appointed a “Grand Mustard-Maker” at the Vatican. By 1904, yellow mustard was introduced in Rochester, New York, and became a staple in American cuisine. The evolution from ancient remedy to modern condiment reflects mustard’s enduring global significance.

How is Mustard Used Beyond the Kitchen?
Mustard is valued not only for its culinary impact but also for its diverse applications outside the kitchen. In many regions, particularly India and Southeast Asia, mustard oil is used in traditional cooking and as a base for massage oils and skin treatments. The oil, extracted from black or brown mustard seeds, is believed to promote circulation and improve skin tone.
Historically, mustard seeds were used for medicinal purposes by the Greeks and Romans, often applied to relieve muscle pain, chest congestion, or arthritis. The high selenium and magnesium content in mustard seeds contributes to anti-inflammatory effects. Mustard poultices—made by crushing seeds and mixing with warm water were used to treat colds and minor infections.
In agriculture, mustard plants serve as cover crops, helping to reduce soil erosion, suppress weeds, and recycle nutrients. Their fast growth and ability to release natural biofumigants make them useful in sustainable farming practices.
These uses show that mustard is not just a food; it’s a multipurpose plant with culinary, medicinal, and environmental benefits.
