glabrous, or with distant scattered hairs, especially on the petioles 
and veins of the leaves. 
Common Tansy. 
French, Tanaisie Commune. German, Rain/am. 
The Tansy is a common plant in many parts of the country, being generally found 
here and there on the borders of fields and by roadsides, where the soil is chalky 
or sandy. 
The herb is bitter, aromatic, and tonic, and its flavour is not unpleasant. It is 
occasionally used in the country as a domestic medicine in intermittent fevers, and 
also as a vermifuge, the leaves being generally made into an infusion which is taken as 
tea. The active properties of the plant reside in the essential oil, which gives it its 
strong and peculiar odour ; but it likewise contains a bitter resinous matter, and an 
acid called tanacetic acid. The essential oil is obtained from the herb by distillation ; it 
has been used as a vermifuge, but in one case with fatal results. Boerhaave held the 
plant in great esteem, and recommended it as a spice, saying, "this balsamic plant may 
supply the place of nutmegs and cinnamon, for I believe that Asia does not supply a 
plant of greater fragrance than the Tansy." It is very little cultivated at present, 
though its leaves are sometimes used in omelettes, and also for colouring other dishes. 
It was formerly eaten much in Lent, as the representative of the bitter herbs com- 
manded to be eaten with the Paschal lamb ; and Tansy puddings and Tansy cakes, 
made from the young leaves mixed with eggs, are still in favour with some people. 
( ferarde alludes to the use of it in cookery in his day ; he says — "In the spring time 
are made with the leaves hereof newly sprung up, and with egs, cakes, or Tansies, which 
be pleasant in taste and good for the stomacke. For if any bad humours cleave 
thereunto, it doth perfectly concoct them and carry them off. The root preserved with' 
hony or sugar is an especiall thing against the gout, if every day for a certaine space, 
a reasonable quantity thereof be eaten fasting." It was likewise considered a specific 
in dropsy. Dr. Threlkeld relates a case of a soldier at Montpellier, who was cured of 
an obstinate dropsy by the decoction of Tansy alone. The same writer accounts for 
tho habit of eating Tansy-cakes during Lent, on the ground that they " dissipate the 
flatulencies occasioned by the idle conceit of eating fish and pulse for forty days ; -but," 
says he, " I have seen several victims to superstition, who have broken an hale consti- 
tution by that presumptuous fasting, so that neither Tansy nor steel could repair it."
