ender it not likely to be used in mistake
for any culinary vegetable; and although we know what its effects are
from report, we do not think it of so dangerous a tendency as some of
our poisonous vegetables.

DRASTIC POISONS.

These purge both upwards and downwards with great violence by means of
their acrid poisonous resin, which also violently affects the throat and
passages. Although alkalies have been recommended in this case, in order
to divide this resin, and that a solution of soap is proper, yet the
vegetable acids are also very useful, and have a great effect in
diminishing the purgative effect. Besides this, it appears still more
advantageous to give astringents: Venice treacle, decoctions of bark or
cascarilla, pomegranate rind, and balaustines; all which certainly
precipitate this drastic principle.

644. ASCLEPIAS syriaca. SYRIAN DOGSBANE.--All the species of Asclepias
have a white acrid juice which is considered poisonous. It is observed
to be very acrid when applied to any sensible part of the mouth or
throat.

645. BRYONIA alba. WILD VINE, or WHITE BRYONY.--The berries of this
plant, when hanging on the hedges, have the appearance of white grapes,
and have been eaten by children. They are known to produce dreadful
effects; but it frequently happens that they produce nausea on the
stomach, by which they operate as an emetic of themselves.

646. EUPHORBIA Lathyris. CAPER SPURGE.--A plant common in old gardens,
but not indigenous. The seed-vessels are much in shape of caper-buds:
hence its name. People have been in the habit of pickling these berries,
from which some dangerous symptoms have arisen; it is probable that the
vinegar may have been the means of checking its bad effects. It should,
however, never be used as food.

647. EUPHORBIA amygdaloides. WOOD SPURGE.--The juice of this plant has
been known to produce very dangerous swellings in the mouth and throat
of persons who have occasionally put it into their mouths. We do not
know that it is very dangerous; and nothing is likely to tempt any
persons to use it as food or otherwise.

648. MERCURIALIS perennis. DOG'S MERCURY.--This plant is of a soporific
deleterious nature, and is said to be noxious to both man and beast.
Many instances are recorded of its fatal effects.
