diethylstilbestrol

A synthetic estrogen hormone. DES was used widely in the United States as a growth promoter in cattle and sheep and as a treatment for estrogen-deficiency disorders in veterinary medicine, and for postcoital contraception. However, because of its carcinogenic properties and other adverse effects, the Food and Drug Administration has revoked all use of it in food-producing animals.
