Lambquarters (Chenopodium album) is an erect, commonly found annual weed that is found in gardens, fields, and waste areas throughout the United States. It produces greenish-white flowers in densely flowered spikes and diamond-shaped, coarsely toothed green to white leaves. Lambsquarters has an abundance of beneficial vitamins and minerals, and has a higher nutritional value than spinach. It is used often by the Native Americans, who use the leaves to aid in the treatment of stomachaches and prevention of scurvy. The leaves can also be used to make a poultice for swelling and burns.
C. album can be used for endoparasites in poultry. It possesses anthelmintic activity in vitro and in vivo against mature Haemonchus contortus and its eggs and found to be only slightly less effective than Levamisole.
If poultry are provided access to C. album they will often nibble on it as a form of self-medication against internal parasites.
