The plant has dull green
leaves The flowers are
bell-shaped and are a dull, unremarkable shade of purple, which yield shiny
black berries
about 1
cm in diameter. It is an
herbaceous shrub, and can grow to be about one metre tall. The
leaves have an oily, "poison
ivy"-like feel to them; they can indeed cause vesicular
pustular eruptions if handled carelessly. Many animals, such
as rabbits,
birds and deer, seem to eat
the plant with impunity, not suffering any deleterious effects, though dogs and
cats are affected.
Many reports suggest that some humans have been poisoned simply by eating
animals that have eaten some of the leaves, although these reports may be
apocryphal.Germination is often difficult due to the presence of
germination
inhibitors in the seeds. Because of its name, it is not common as a garden
plant, and is considered a weed in some
places. It is not as hardy a perennial as the literature would lead one to
believe, and will not tolerate transplantation. Germination requires several
weeks in warm, moist, absolutely sterile soil, usually far
from normal garden conditions.
True to its name, Belladonna is one of the most toxic plants to
be found in the
Western hemisphere. Children have
been poisoned by as few as three of the berries, and a small leaf thoroughly
chewed can be a fatal dose for an adult. The root
is often the most toxic part, though this can vary from one specimen to
another.All parts of the plant, especially the root, contain tropane alkaloids. The
berries often present the greatest danger to children as they have a somewhat
sweet taste, though they are the least toxic part of the plant. Symptoms of
belladonna
poisoning are the same as those for atropine (the most well known of the
tropane alkaloids), and include dilated pupils,
tachycardia,
hallucinations, blurred
vision, loss of
balance, a
feeling of flight,
staggering, a sense of
suffocation, paleness followed by a red rash, flushing,
husky voice, extremely dry throat,
constipation,
urinary retention, and
confusion. The skin can completely dry out and slough off. Fatal cases
have a rapid pulse
that turns feeble. The antidote
is
physostigmine or
pilocarpine, the same as for atropine.The plant is also toxic to many domestic animals and livestock; for
instance, poisoning can lead to colic,
depression, weakness, and lack of coordination in horses, with
fatalities reported even for small amounts from 1 to 10 pounds (0.5 to 5 kg)
The name belladonna originates from the historic use by ladies (Bella
Donna is
Italian for beautiful lady) to dilate
their pupils;
an extract of belladonna was used as eye drops
as part of their makeup preparations. The Belladonna Toxin's atropine
content had the effect of dilating the pupil, thus
making their eyes supposedly more attractive. Dilated pupils are considered
more attractive (especially with females)
because pupils normally dilate when a person is aroused,
thus making eye
contact much more intense than it already is. It had the
adverse effect of making their
vision a little blurry and making their heart rates increase.WitchcraftAccording to practitioners of
witchcraft, nightshade is ruled by Hecate and
can turn into an old hag on
Walpurgis Night, or
April 30.
It is also used in
flying ointments. Of the twelve recipes for flying ointments, six call for
deadly nightshade.According to legend, this is the favorite plant of the devil, and can only
be harmed when he is diverted from its care on the Walpurgis.Modern medicineThe plant is the most important source of atropine, ironically an effective
cure for the effects of poisoning
by potent
cholinesterase inhibitors such as Parathion, Malathion
and, most infamously, Sarin, VX, and similar nerve
agents. In Europe, it is specifically cultivated for that reason.Optometrists and
ophthalmologists use belladonna to this day for pupil dilation in eye
examinations, though the dose is extremely small.Recreational drugOccasionally, the plant is used for recreational purposes: it is consumed
in the form of either a
tea or simply raw, which can produce vivid hallucinations, described by
many as a 'living dream'. The effects of even a slight poisoning are so
unpleasant that the recreational user is unlikely to attempt its use again, if
he or she survives at all.
