TANSY, Tanacetum vulgare L., contains a violent, irrit- 
ant, narcotic poison, producing spasms and convulsions, 
but is very rarely eaten by animals. It was introduced 
into this country from Europe, and has escaped from gar- 
dens in various places. 
It is a bitter and strong-scented herb, two to four feet 
high, with tough parsley-like leaves. The heads, each 
containing many yellow, tubular florets and few ray flor- 
ets, are borne in dense flat corymbs.
