Mustard was widely used as a medicinal remedy by physicians and households during the 1800s [2].

This historical practice highlights the evolution of pharmacology and the previous reliance on common dietary staples to manage physical ailments. It demonstrates how the understanding of therapeutic compounds has shifted from domestic kitchen applications to standardized clinical medicine.

In Western Europe and the U.S., the condiment was valued for its pungent compounds. Practitioners said these properties provided therapeutic effects for various respiratory and muscular ailments [1]. Because of these perceived benefits, mustard was frequently applied as a poultice, a soft, moist mass of material applied to the body to relieve soreness and inflammation [1].

Beyond its use as a poultice, the substance was employed to treat common colds and general muscle aches [1]. This application was part of a broader trend where everyday foods were repurposed as medicine. According to reports on historical health practices, mustard is among 15 foods that were once considered medicinal [1].

While modern medicine has replaced these home remedies with targeted pharmaceuticals, the use of mustard in the 19th century [2] reflects a period of transition in medical science. The practice relied on the stimulating effect of the mustard plant on the skin and respiratory system to draw out congestion or increase blood flow to injured muscles [1].

The use of mustard as a 19th-century medical tool illustrates the historical overlap between nutrition and pharmacy. Before the advent of synthetic drugs, the 'doctrine of signatures' and the observation of botanical stimulants led practitioners to use dietary items to treat systemic inflammation and congestion.
