Food:

"Leaves are mildly spicy, but somewhat dry textured, so it is best to combine them with others, fresh, in salads. Cook in stir-fries, casseroles, soups, omelets, bean dishes, and quiche. Excessive cooking reduces spiciness. Also, seeds are edible and sproutable." (Seebeck 93)

"Tender young shoots provide a zesty addition to salads and sandwiches, and stronger plants are best used as flavoring in soups, salads and casseroles." (Kershaw 120)

Medicine:

"These plants are rich in vitamins A, B and C and also contain considerable amounts of trace minerals. The seeds, which are said to stimulate the production of digestive juices, have been used for many years as an aid for digestion. --- Mustard seed has also been used in poultices for healing wounds, and it was sometimes taken in large quantities as a laxative." (Kershaw 120)

Other Uses:

"Tansy mustard is used to produce pottery paint and is prepared in much the same way as guaco (the paint made from Rocky Mountain beeplant). --- seeds of tansy mustard are ground in a mortar until an oily liquid forms; this liquid is than mixed with iron pigment and used to paint patterns on pottery." (Dunmire and Tierney 181)
