Overview
White mustard is an annual plant producing small yellow flowers and seed pods containing pale yellow seeds. The seeds have been used medicinally and culinarily for thousands of years. Rich in compounds that stimulate circulation and digestion, white mustard seeds are valued for their warming, stimulating properties and ability to support respiratory and digestive health.
Traditional Use
White mustard has been used since ancient times in Greek, Roman, and traditional Chinese medicine. The seeds were used to stimulate digestion, create warming poultices for chest congestion and muscle pain, and as a rubefacient to increase blood flow to affected areas. Mustard plasters were a common home remedy for respiratory congestion.
