The genus name of garlic mustard (Alliaria) is partly derived from the genus name for garlic (Allium) because of garlic mustard's strong garlic-like odor.
Garlic mustard is also known as 'sauce-alone' because it was customary to use the plant in sauces and salads.
Garlic mustard is higher in vitamins A and C than many commercially available fruits and vegetables.
Because garlic mustard forms dense colonies on sloping land, it may help prevent soil erosion.
Leaves were applied externally to treat gangrene and ulcers.
