Erisymum, also known as hedge mustard, is a plant native to Europe and North Africa. This member of the Brassicaceae family, which grows in various temperate regions, is distinguished by its slender height and small yellow flowers. Beyond its nutraceutical uses, hedge mustard has historical significance, as its seeds were traditionally used to add a pungent flavour to cheese and other foods.
Fun fact: it is thought that hedge mustard was used by singers to keep their voices strong.
