a starch, named "inulin,"
which is peculiar as not being soluble in water, alcohol, or ether;
and conjointly a volatile oil, a resin, albumen, and acetic acid.
Inulin is allied to starch, and its crystallized camphor is separable
into true helenin, and alantin camphor. The former is a powerful
antiseptic to arrest putrefaction. In Spain it is much used as a
surgical dressing, and is said to be more destructive than any other
agent to the bacillus of cholera. Helenin is very useful in
ulceration within the nose (_ozoena_), and in chronic bronchitis to
lessen the expectoration. The dose is from a third of a grain to two
grains.

Furthermore, Elecampane counteracts the acidity of gouty
indigestion, and regulates the monthly illnesses of women. The
French use it in the distillation of absinthe, and term it _l'aulnee,
d'un lieu plante d'aulnes ou elle se plait_. To make a decoction,
half-an-ounce of the root should be gently boiled for ten minutes
in a pint of water, and then allowed to cool. From one to two
ounces of this may be taken three times in the day. Of the
powdered root, from half to one teaspoonful may be given for a
dose.

[175] A medicinal tincture (H.) is prepared from the root, of
which thirty or forty drops may be taken for a dose, with two
tablespoonfuls of cold water; but too large a dose will induce
sickness. Elecampane is specifically curative of a sharp pain
affecting the right elbow joint, and recurring daily; also of a
congestive headache coming on through costiveness of the lowest
bowel. Moreover, at the present time, when there is so much talk
about the inoculative treatment of pulmonary consumption by the
cultivated virus of its special microbe, it is highly interesting to
know that the helenin of Elecampane is said to be peculiarly
destructive to the bacillus of tubercular disease.

In classic times the poet Horace told how Fundanius first taught
the making of a delicate sauce, by boiling in it the bitter _Inula_
(Elecampane); and how the Roman stomach, when surfeited with
an excess of rich viands, pined for turnips, and the appetising
_Enulas acidas_ from frugal Campania:--

"Quum rapula plenus
Atque acidas mavult inulas."

Found in abundance in summer time on our heaths, and on mountains
near the sea, this delicate little plant, the _Euphrasia
officinalis_, has been famous from earliest times for restoring and
preserving the eyesight. The Greeks named the herb o
