nce to the stimulating effects of
the herb on the sexual organs. Its tuberous root has been found to
contain a particular volatile acrid principle which exercises distinct
medicinal effects, though these are altogether dissipated if the
roots are subjected to heat by boiling or baking. When tasted, the
fresh juice causes an acrid burning irritation of the mouth and
throat; also, if swallowed it will produce a red raw state of the
palate and tongue, with cracked lips. The leaves, when applied
externally to a delicate skin will blister it. Accordingly a tincture
made (H.) from the plant and its root proves curative in diluted
doses for a chronic sore throat, with swollen mucous membrane,
and vocal hoarseness, such as is often known as "Clergyman's
Sore Throat," and likewise for a feverish sore mouth, as well as for
an irresistible tendency to sleepiness, and heaviness after a full
meal. From five to ten drops of the tincture, third decimal strength,
should be given with a tablespoonful of cold water to an adult
three times a day. An ointment made by stewing the fresh sliced
root with lard serves efficiently for the cure of ringworm.
The fresh juice yields malate of lime, whilst the plant contains
gum, sugar, starch and fat. The name Arum is derived from the
Hebrew _jaron_, "a dart," in allusion to the shape of the leaves like
spear heads; or, as some think, from _aur_, "fire," because of the
acrid juice. The adjective _maculatum _refers to the dark spots or
patches which are seen on the smooth shining leaves of the plant.
These leaves have sometimes proved fatal to children who have
mistaken them for sorrel. The brilliant scarlet coral-like berries
which are found set closely about the erect spike of the arum in the
autumn [35] are known to country lads as adder's meat--a name
corrupted from the Anglo-Saxon _attor_, "poison," as originally
applied to these berries, though it is remarkable that pheasants can
eat them with impunity.
In Queen Elizabeth's time the Arum was known as starch-wort
because the roots were then used for supplying pure white starch
to stiffen the ruffs and frills worn at that time by gallants and
ladies. This was obtained by boiling or baking the roots, and thus
dispelling their acridity. When dried and powdered the root
constitutes the French cosmetic, "Cypress Powder." Recently a
patented drug, "Tonga," has obtained considerable notoriety for
curing obstinate neuralgia of the head and face--th
