--><p>Crops of <i>Brassica</i> are the most important economic plants of the family. Probably, the earliest known utilization of mustards dates from Sanskrit records in India to 3000 b.c., but there is archaeological evidence suggesting that cultivation of cabbage in coastal northern Europe was occurring nearly 8000 years ago. <i>Brassica</i> crops include oilseeds, food crops (e.g., <i>B. juncea</i>, Asian vegetables; <i>B. oleracea</i>, cole crops; <i>B. rapa</i>, Chinese cabbages), fodder for animals, and condiments (<i>B. juncea</i> or <i>B. nigra</i>). The latter two species have also been used for medicinal purposes (I. A. Al-Shehbaz 1985). In addition to being noxious weeds, some species of <i>Brassica</i> are harmful or poisonous to humans and livestock (Al-Shehbaz).</p><!--
--><p>Historically, native peoples of North America have used a number of “wild” <i>Brassica</i> species for both food and medicinal purposes (T. Arnason et al. 1981; H. A. Jacobson et al. 1988): <i>Brassica</i> species—young shoots cooked as greens by Iroquois and Malecite Indian tribes; <i>B. nigra</i>—seeds ground and used as snuff to cure head colds by the Meskwaki, and leaves used to relieve toothaches and headaches by the Mohegans; <i>B. napus</i>—bark used to treat colds, cough, grippe, and smallpox by the Micmac, and used for chilblains by the Rappahannock; <i>B. oleracea</i>—used for headaches by the Rappahannock; and <i>B. rapa</i>—used as medicine by the Bois Fort Chippewa.</p>
