Tansy
tan-zy, a coarse wayside plant of the composite family. It has a flat top of small yellow heads like those of a goldenrod, and dark-green cut leaves reminding one of certain ferns. It came over with the white people from Europe. Tansy thrives under wagon wheels in hard soil and dust, where it disputes the right of possession with dogfennel. The leaves contain a bitter aromatic oil. Tansy was once used as a flavoring and persistently as a household remedy for various disorders of the stomach and for muscular rheumatism. It has fallen into disfavor for culinary purposes, but it still holds a place as a remedy. The oil is a narcotic. Taken in sufficient quantity it is an active poison. See Medicine
