Epazote is such an herb. Epazote is used medicinally to treat internal parasites. Epazote is an abundant weed in Mexico and parts of northern South America. There, its bitter, musky, lemon flavor is used to spice up everything from beans and squash to pork and crab cakes. Young leaves can be wilted and added to soups or stews or combined with other greens, just as chicory or sorrel would be used in early spring. It is often used with other herbs, like Mexican Oregano and Cilantro, and, of course, chilies.
