INTRODUCTION


Prompted by the many telephone calls and inquiries received at the
Rhode Island Poison Control and Information Centers regarding plants,
flowers, and berries, the State Department of Health has developed
the information contained in this booklet. It will aid families in
planning safe gardens, give fuller knowledge of wild plants, and, in
the case of an accidental ingestion, provide assistance in identifying
the plant. Since verbal descriptions are frequently inadequate, and
nonprofessional determination of species often uncertain, there has
been a need for a more expedient means of identifying plants and their
toxicity.

Because the toxicity of these plants will vary with the size of the
child, the season, and the quantity and part of the plant eaten, it is
necessary that a physician determine the necessary treatment for each
case.

    =THIS BOOKLET ENCOURAGES THE EMPTYING OF THE
      STOMACH OF A VICTIM BY VOMITING AS A GENERAL
      MEASURE IN PREVENTING SERIOUS INJURY.

      VOMITING SHOULD NOT BE INDUCED IF THE VICTIM
      IS UNCONSCIOUS OR CONVULSING.=

Some basic information is included for physicians who might be unaware
of the toxic principles and their effects in these particular plants.
Although the seriousness of each accident must be judged individually,
it is necessary that the plant be accurately identified and that
sufficient information on its toxicity be readily available. Many
other poisonous plants could have been included in this booklet, but,
the purpose was to discuss those found most commonly, although not
exclusively, in the New England States.

The names and telephone numbers of the Poison Control Centers in the
New England area are included for the convenience of your physician.

AMANITA MUSHROOM


[Illustration: Amanita, fly agaric

_Amanita muscaria--AGARICACEAE_]

=Description=: One of the most poisonous of the mushrooms (toadstools).
Found mostly in woody areas, along roadsides, and waste places,
especially at the base of pine and similar trees. Unlike many edible
mushrooms, this poisonous amanita has a fleshy bulb-like base and
yellow stalk (stipe) with scaly growths and a cap or top (pileus).
Often a white ring (annulus) of soft ragged tissue may be observed on
the stalk under its cap. All amanita mushrooms should, in general, be
considered poisonous. The top, which may be 3 to 6 inches wide, varies
in color from bright orange to red with white to gray warty growths on
it. Under the cap are numerous very white gills which distinguish this
mushroom from most edible types. The latter usually have pink to purple
gills. These mushrooms form in groups, or are scattered.

Other poisonous mushrooms found in New England are the Death Cup,
_Amanita phalloides_; jack-o’-lantern, _Clitocybe illudens_; Shaggy
mane, _Coprinus comatus_; and the _Boletus_ and _Russula_ species.
There are many others. Perhaps the best precaution is to avoid eating
any mushroom not certified by an expert to be edible.

=Poisonous Parts=: All portions are poisonous. The chief toxic
principle is an alkaloid, =muscarine=. Amanita poisoning is
characterized by intense sweating, salivation, wheezing, irregular
breathing and heart beat. If not treated promptly, it =can be fatal=
within an hour depending upon quantities consumed.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat for =muscarine= alkaloid poisoning or
excessive muscarinic stimulation of the parasympathetic nervous system,
also dehydration. Atropine and other similar drugs counteract the
effects of =muscarine=.



BANEBERRY


[Illustration: Baneberry, snakeberry

_Actaea rubra and Actaea alba--RANUNCULACEAE_]

=Description=: The red and white baneberries are perennial herbs found
in woodlands and occasionally as showy plants in gardens. Leaves are
large on many branches and resemble those of the wildcurrant. The small
flowers are white in spring. Plants generally grow about 1 to 2 feet in
height. The attractive parts are the red or white berries which develop
during summer and early autumn. They are in clusters on terminal flower
stalks, each on a conspicuous short fleshy pedicel. Children have been
poisoned by eating the berries.

=Poisonous Parts=: The root stock, sap, and berries. These produce
marked irritation of the stomach and intestines causing nausea and
violent purgation. If absorbed, the acrid principles can affect the
heart, increase the pulse rate, and cause dizziness. Fatalities have
been reported.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat gastric inflammation and circulatory failure.



BITTERSWEET


[Illustration: European bittersweet, blue nightshade, woody nightshade

_Solanum dulcamara--SOLANACEAE_]

=Description=: A woody climbing or reclining herb with slender stems
and dark green pointed leaves which may be purplish-green when young.
Clusters of white or purplish-white flowers borne on a 5-pointed,
wheel-shaped base (calyx). During summer and early fall, fruits become
attractive berries, bright red to scarlet, and are scattered in
clusters. They remain when leaves fall.

This weed is found in numerous areas, such as on dumps, along fence
walls, and generally in moist, rich soil conditions. It is a common
weed in many gardens, near dwellings or in fields, and is related to
the black and deadly nightshades.

NOTE. The black nightshade, American bittersweet or poison berry
(_Solarium nigrum-SOLANACEAE_) closely resembles the European
bittersweet, excepting the berries which are purple or black. It
contains the same poisonous principles.

=Poisonous Parts=: Chiefly the leaves and unripe fruits. The red
berries (black berries of the black nightshade) can be poisonous if
several are eaten. The plant contains =solanine=, =dulcamarin=, and
similar principles which are related to the alkaloids of the deadly
nightshade. Poisoning is characterized by burning in the throat,
nausea, dizziness, dilation of eye pupils, convulsions, and general
muscular weakness.

=Antidote=: Call your doctor. Have patient vomit. Physicians treat for
alkaloids, as in atropine poisoning.



BLOODROOT


[Illustration: Bloodroot

_Sanguinaria canadensis--PAPAVERACEAE_]

=Description=: Perennial, low-growing herbs which appear early in
spring in shady, moist wooded areas. The many-petaled, white flower
frequently develops first on a stalk wrapped with a single large-lobed
leaf. The large underground stem (rhizome) and smaller roots of the
bloodroot contain an orange to red juice from which the plant gets its
name. This is poisonous.

=Poisonous Parts=: The underground stems, roots, and their
red contents. These contain several toxic alkaloids, chiefly
=sanguinarine=, which irritate the mucous membranes of the mouth,
throat, and stomach causing intense burning, nausea, and vomiting. If
absorbed, the alkaloids can affect the nervous system, depress the
heart, cause coma, and produce temporary paralysis.

=Antidote=: Call your doctor. Have patient vomit, and then give
warm milk. Physicians perform gastric lavage and treat irritated
gastro-intestinal tract. In the event that much of the root material
has been ingested and absorbed, measures should be taken to prevent
circulatory collapse.



CASTOR BEAN


[Illustration: Castor bean, castor oil plant, palma Christi

_Ricinus communis--EUPHORBIACEAE_]

=Description=: There are many varieties of the castor bean plant
growing in gardens and greenhouses. The plant is cultivated
commercially in southern climates for the castor oil produced by the
seeds. It grows to 8 feet or more in height with large showy palm like,
dark green leaves on long stalks.

Flowers are not very attractive but the clusters of soft spiny fruits
which form in late summer and early fall, split open to yield very
attractively marked shiny seeds. These possess variegated white to
brown and black striations and are shaped somewhat like the tick
insect. Because of the attractive appearance, they become playthings
for children.

=Poisonous Parts=: The beans or seeds contain the toxic substances
=ricin= and =ricinine=. =Ricin= is exceedingly poisonous due to its
irritant action which causes nausea, vomiting, intestinal cramps,
stupor, and sometimes convulsions and circulatory collapse several
hours after seeds are ingested. =Ricin= may produce hemolysis.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and maintain fluid and electrolyte balance and employ
symptomatic measures.



CHRISTMAS ROSE


[Illustration: Christmas rose, black hellebore

_Helleborus niger--RANUNCULACEAE_]

=Description=: In warmer climates, the large blossoms of this plant
appear in midwinter, hence, the common name Christmas rose. However,
these develop much earlier in fall or later in spring in New England
and other northern areas.

The plant is a perennial evergreen herb with a black underground stem
and roots. Each year a single palmately divided leaf and flower stalk
form, the latter with one or two large purplish-white flowers, each
with five petals and a yellow center whorl of flower parts. Found in
gardens usually as a cultivated plant.

=Poisonous Parts=: An intensely irritating glycoside principle,
=helleborein=, has been found in the leaves and roots. This probably
accounts for much of the skin inflammation caused on contact with
bruised parts or the juice of this plant. Other poisonous glycosides
and alkaloids which affect the heart (similar to the effects of
digitalis) and nervous system (as from aconite) are also present. If
ingested, the plant may cause vomiting, tingling and numbing sensations
in the mouth, and violent purgation.

=Antidote=: Call your doctor. Wash the skin at once with soap and water
if the juice of the plant is in contact with it. Have patient vomit if
any part has been eaten. Physicians treat for dermatitis and vesication
if a contact poisoning. When there is evidence of much ingestion treat
for =digitalis= or =aconitine= poisoning, depending upon symptoms.



DAPHNE


[Illustration: Daphne, spurge olive

_Daphne mezereum--THYMELAEACEAE_]

=Description=: A low, woody plant found in many gardens. The daphne
bears small rose-purple blossoms in clusters along its branches in
early spring before the leaves develop. During the summer, several
bright red berries appear, each with a single seed. Some horticultural
varieties produce white to yellow flowers and yellow to orange berries.

=Poisonous Parts=: The bark, (this separates easily from the stems)
leaves, and berries are poisonous. Children are especially attracted
to the berries and fatalities among some who have eaten them have been
reported.

Poisoning is characterized by a burning sensation in the mouth and
irritation of the stomach and intestines which causes severe cramps.
Toxic principles include a bitter glycoside, =daphnin=, and an acid
resinous mixture. If not removed reasonably soon, these can produce
kidney inflammation since these principles can be absorbed.

=Antidote=: Call your doctor. Have patient vomit. Physicians
perform gastric lavage and treat for a probable irritation of the
gastro-intestinal tract if parts of the plant have been in the stomach
for more than an hour.



DEADLY NIGHTSHADE


[Illustration: Deadly nightshade, black cherry

_Atropa belladonna--SOLANACEAE_]

=Description=: A perennial bushy herb, 3 to 4 feet in height, branching
stems with dark green pointed leaves, lavender-to-purple, bell-shaped
flowers, and black cherry-like fruits. (Not related to cherry trees.)

Plants rarely grown in gardens, usually weeds found in scattered areas.
Children are especially attracted to the fruits.

=Poisonous Parts=: Roots, leaves, and seeds which contain alkaloids
(=atropine=, =hyoscyamine=, =scopolamine=, etc.) similar to those
of the jimsonweed (see page 12). Poisoning causes drying of
the mouth, dilation of eye pupils, a very rapid heartbeat, and
central-nervous-system depression. Poison can be absorbed by handling
leaves, as well as by eating fruits. Severely poisonous!

=Antidote=: Call your doctor. Have patient vomit immediately if eaten.
Exposed skin should be washed with soapy water. Physicians treat for
=atropine= poisoning.

NOTE: Other nightshades causing poisoning include the blue and black
nightshades which are also known as bittersweets (_Solanum dulcamara_,
and _Solanum nigrum_ respectively). (See page 3.)



FOXGLOVE


[Illustration: Foxglove, digitalis

_Digitalis purpurea--SCROPHULARIACEAE_]

=Description=: The foxglove is found wild in woodlands, along shady
roadsides, and often is cultivated in gardens. During its first year
of growth it forms clusters of leaves in a rosette pattern, but no
flowers. The flowers develop on long erect stems early in summer during
the second year. They are numerous showy white-lavender, or purple
bell-shaped flowers which bloom for several weeks. The fruits are dry
capsules with many tiny seeds.

=Poisonous Parts=: The leaves and seeds. These contain the digitalis
glycosides, chiefly =digitoxin=, which is a powerful heart stimulant.
Poisoning is characterized by nausea, vomiting, and dizziness and can
be experienced several hours after ingesting the plant parts. The
plant is severely poisonous and can cause heart failure because of its
powerful action on the heart muscles.

=Antidotes=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat for =digitoxin= and digitalis glycoside
poisoning.



GREEN HELLEBORE


[Illustration: Green hellebore, false hellebore, Indian poke

_Veratrum viride--LILIACEAE_]

=Description=: This hellebore is found in swampy places, moist meadows,
or along the edges of streams. It develops in early spring quite like
the skunk cabbage, but then grows during summer on a stout stalk up to
6 to 8 feet in height. Its clasping broad leaves with parallel vein
markings are conspicuous. Many small greenish-white flowers form on a
branching top.

The size of the plant attracts people, and children find the broad
leaves and green tops a curiosity. Powdered roots and a mixture of the
alkaloids are found among the contents of some insecticides.

=Poisonous Parts=: Poisonous principles are alkaloids which are
in largest amounts in the roots. Leaves and seeds contain smaller
quantities and can be harmful. Poisoning is characterized by
salivation, abdominal pain, and attempts to vomit. Large quantities
produce a cold and clammy skin and depressed circulation due to effects
of =veratrum= alkaloids on the heart muscles and on respiration. Death
may result.

=Antidote=: Call your doctor. Have patient vomit if the victim has
not become unconscious and appears calm. If shock has developed, use
standard first aid measures. Physicians treat for =veratrum= alkaloid
poisoning.



INDIAN HEMP


[Illustration: Indian hemp, cannabis, marihuana, marijuana

_Cannabis sativa--MORACEAE_]

=Description=: This tall annual weed is usually eradicated by local
authorities as soon as it is found because of its narcotic properties.
Occasionally, however, it turns up on dumps, along railroad tracks,
or other places. Fruits or “seeds” of the _Cannabis_ for commercial
purposes, have been pre-treated to render them non-viable and of use
in bird seed mixtures. At times, some are not rendered sufficiently
sterile and these, in the home refuse, get to dump areas where they
germinate. Plants can reach more than 6 feet in height.

Leaves are slender and divided into five to seven long, narrow, pointed
leaflets each with a saw-tooth margin. They are rough to the touch,
giving one the feeling of sand paper. Smaller flower bracts are quite
resinous and sticky. Flowers and fruits are rather inconspicuous and
scattered along upper portions of the stem. Male and female flowers are
borne on separate plants.

=Poisonous Parts=: The leaves, flowering parts, and resinous secretions
contain the _Cannabis_ (=cannabinol=) narcotic principles. Publicity
over the illegal use of marihuana in its various forms, i.e.,
cigarettes, extracts, pills, etc., make it a curiosity among some
people. It causes cerebral stimulation and excessive amounts produce
hallucinations, delirium, and eventually mental depression. It is a
plant which can cause drug addiction.

=Antidote=: Call your doctor. Have patient vomit. Physicians treat for
cerebral depression and other aspects of marihuana poisoning.



JIMSON WEED


[Illustration: Jimson weed, thornapple. Jamestown weed

_Datura stramonium and Datura tatula--SOLANACEAE_]

=Description=: An annual herb, 3 to 4 feet in height, branching stems
with trumpet-shaped white flowers or thorny fruits formed in forks
of the branches. Leaves pointed and with irregular margins. _Datura
tatula_ has purple stems. Both have spiny or prickly fruits which
turn brown when ripe and spill out several small brownish-black,
kidney-shaped seeds. These are also poisonous.

=Poisonous Parts=: Roots, leaves, and seeds which contain alkaloids
(=atropine=, =hyoscyamine=, =scopolamine=, etc.) similar to those
of the deadly nightshade. (See page 8.) Poisoning causes drying
of the mouth, dilation of eye pupils, a very rapid heartbeat, and
central-nervous-system depression. Poisoning can be experienced merely
by handling the leaves. Children sometimes ingest the poisonous seeds
or rub the eyes after touching the leaves and are then poisoned.

=Antidote=: Call your doctor. Have patient vomit. Hands should be
washed with soap and water if in contact with the plant. Physicians
treat for =atropine= poisoning.

NOTE: There are other species and varieties of _Datura_ which contain
similar poisonous principles although in lesser amounts. These are
sometimes grown in gardens and greenhouses as ornamentals and are
frequently called angel’s trumpet. They include _Datura innoxia_,
_Datura metel_, _D. metaloides_, _D. arborea_, _D. sanguinia_, etc.
Most have large trumpet-like, white or pinkish-white flowers and some
reach small tree height. Observe same precautions as for jimson weed.



LARKSPUR


[Illustration: Larkspur, delphinium, lark’s claw, knight’s spur

_Delphinium ajacis--RANUNCULACEAE_]

=Description=: The cultivated larkspurs found in New England are
annuals or perennials found in many gardens and produce showy blossoms
with many colors (usually white and violet-purple) growing on erect
flower stalks. Leaves are divided into parts and have the general
outline of a bird’s foot. The small seeds which form in dry follicles
are usually pointed and very irregular in shape. The plant varies in
height from 2 to 4 feet.

=Poisonous Parts=: Leaves and seeds contain toxic alkaloids which when
ingested may affect the nervous system. Tingling sensations of the
mouth may at first be experienced followed by excitation and severe
depression. Animals poisoned by wild larkspurs growing on western
ranges stagger and appear to develop symptoms of tetany. Powdered
larkspur seed is also found in some commercial lice remedies.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat for alkaloid (=ajacine=) poisoning and central
nervous system excitation using short-acting barbiturates because of
subsequent depression.



LILY-OF-THE-VALLEY


[Illustration: Lily-of-the-valley

_Convallaria majalis--LILIACEAE_]

=Description=: A perennial, low-growing herb found in many gardens.
Its attractive small, white, nodding, bell-shaped flowers are fragrant
and used in bouquets. They blossom in spring and summer. Several of
these are found on one side of a slender flowering stalk. Leaves have
parallel vein markings. The fruits appear in late summer and early fall
and are attractive red to orange-red fleshy berries.

=Poisonous Parts=: Roots, leaves, and fruits contain harmful
principles, particularly the glycoside =convallatoxin= which stimulates
the heart muscles similarly to the poisonous principles of the
=foxglove=, =digitalis=. Dizziness and vomiting may occur in 1 to 2
hours if large quantities are eaten.

=Antidote=: Call your doctor. Have patient vomit. Physicians should
look for symptoms of digitalis poisoning.



MONKSHOOD


[Illustration: Monkshood, aconite, friar’s cap, Wolfsbane

_Aconitum napellus--RANUNCULACEAE_]

=Description=: There are numerous garden varieties of the monkshood
and it is widely cultivated. It is a perennial herb reaching a height
of about 3 to 4 feet with many divided leaves (like a crow’s foot).
Several violet-blue flowers form on a flowering stalk somewhat like the
delphinium or larkspur, but they are more frequently branched. Each
flower resembles the cap or hood of a medieval monk, hence its common
name. The seeds are tiny and form in dry capsules called follicles.

=Poisonous Parts=: Roots and seeds are most poisonous although the
leaves may be harmful if eaten. The plant contains several poisonous
alkaloids, chiefly =aconitine=, which affects the vital vagus nerve
from the brain causing a slowing of the heart. Other effects of
poisoning include tingling and numbing sensations of the lips and
tongue, irregular pulse, dimness of vision, and respiratory failure.

=Antidote=: Call your doctor. The victim should be kept warm, because
of the possibility of circulatory collapse, and placed in a horizontal
position with the feet level with the head. Physicians treat for
=aconitine= alkaloid poisoning. Gastric lavage is preferred to the use
of vomiting agents. Circulatory stimulants may be necessary.



POISON HEMLOCK


[Illustration: Poison-hemlock, poison-parsley

_Conium maculatum--UMBELLIFERAE_]

=Description=: A biennial weed with leaves resembling those of parsley,
dark green, finely divided, with shiny under surfaces. The plant is
found in gardens, fields, and along roadsides, and reaches up to
5 feet, or more, in height. Roots resemble those of the parsnip.
When crushed, both fresh leaves and roots yield a juice with a
characteristic odor of the parsnip. Occasional purplish spots are found
on the hollow stems.

The very small white flowers and grayish-green fruits are borne on
umbrella-like stalks. The tiny fruits upon close examination have
flattened inner surfaces. They also look somewhat like fruits of the
anise, _Pimpinella anisum_.

=Poisonous Parts=: The leaves and fruits during flowering contain an
intensely poisonous principle, =coniine=, and other related alkaloids.
Older roots are also poisonous. Hemlock poisoning first causes a
burning sensation in the mouth and throat followed by muscular
weakness, stupor, and paralysis of the arms and chest. Poisonous
principles act on the spinal cord and brain causing respiratory failure
and death.

The poisonous hemlock juice was employed by ancient Greeks as a means
of capital punishment. Socrates and other celebrities are said to have
met death by this means. Accidental poisoning has occurred in modern
time by mistaking the conium for parsley, parsnip, or anise plants.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage as soon as possible. Treat for alkaloid poisoning and
maintain respiration.



POISON-IVY


[Illustration: Poison-ivy, poison-oak

_Rhus Toxicodendron--ANACARDIACEAE_]

=Description=: Probably no other plant has caused as much suffering and
distress as has the poison-ivy. Poison-ivy, with its characteristic
three-leaf appearance and prominent veins is a woody vine, climbing by
aerial rootlets, or taking a tree-like appearance. Poison-oak is more
of a low, branching shrub. Each leaflet is shaped somewhat like an oak
leaf. Both are found abundantly in woodlands, along fences, walks,
and roadsides. During the fall their showy red and yellow leaves are
frequently mistaken for those of the harmless trees of the woods.

The flowers are yellowish green to white in color and formed in
clusters attached to the stems, or in the stem forks. Fruits are smooth
globular structures, sometimes remaining on the branches until spring.

=Poisonous Parts=: All parts of the plant are poisonous, even the tiny
plant hairs and the smoke from burning the leaves in the fall. This
plant produces a severe dermatitis upon contact causing inflammation,
blistering, and vesicles. As the skin breaks, a liquid exudes and scabs
or crusts form.

The poisonous principle is a reddish-brown, oil-resin containing
=urushiol=. This can produce irritant effects within 24 hours upon
contact with the skin.

=Antidotes=: Numerous remedies are available in pharmacies for
poison-ivy. After contact, or suspected contact, hands, face, and
affected parts should be first washed freely with soapy water using
laundry soap of the alkali kind; lather abundantly. Soaps containing
oil or greasy components should not be used. The poison is soluble in
them and will spread over the skin. In severe or persistent cases of
dermatitis, consult your physician.

Physicians treat itching, severe inflammation, and pain when dermatitis
becomes evident.



POKEWEED


[Illustration: Pokeweed, pigeonberry, American nightshade, ink berries,
scoke

_Phytolacca americana, P. decundra--PHYTOLACCAEAE_]

=Description=: A perennial weed, growing up to about 4 feet, with a
large fleshy root system. Stems are rather thick and leaves have a
light green appearance with prominent ribs (veins) and somewhat curled
edges.

Flowers are greenish-white and borne on a spike in the upper part of
the plant. As the many berries form in clusters in late summer and
early autumn, they are at first green then reddish-purple, later purple
to black, and contain a red juice which has also given the plant the
name red-ink plant. Birds frequently feed on them. The plant is found
in many areas.

=Poisonous Parts=: All parts are poisonous, particularly roots, shoots,
and unripe berries. As the berries ripen, their poisonous properties
lessen but, nevertheless, if many are eaten, they too can be harmful.
Toxic materials include a resinous material and a water-soluble
=saponin=. No alkaloid has as yet been found in pokeweed.

Poisoning generally is slow (1 to 2 hours) after ingesting the plant
but then becomes violent for a long time. Following a period of nausea
and vomiting, drowsiness and impaired vision results. Large amounts can
cause purgation and narcosis followed by coma and death.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat for circulatory and respiratory depression.



WATER HEMLOCK


[Illustration: Water hemlock, cowbane, beaver poison

_Cicuta maculata--UMBELLIFERAE_]

=Description=: A perennial herb reaching to 5 feet, or more, in height
and found in swampy or moist areas. At least eight species of _Cicuta_
are known to be poisonous.

As in the Conium hemlock, the roots of _Circuta_ resemble those of the
parsnip but in addition, frequently possess many tuberous rootlets
which resemble small sweet potatoes. When cut open, these yield a
yellowish aromatic oil. Stems are shiny, hollow, and often have purple
spots. Leaf bases clasp around the stem and the leaves are coarsely
divided into smaller leaflets.

Flowers are white and the small fruits are formed on umbrella-like
stalks. Each fruit possesses several prominent corky ribs.

=Poisonous Parts=: Mostly the roots. However, above ground parts are
also very poisonous and should be avoided. The similarity of roots to
parsnip and sweet potato has led to accidental poisoning in children
and adults. The poison principle is a resin-like substance called
=cicutoxin= and a small quantity of this can cause death.

Poisoning is characterized by severe stomach pain, great mental
excitation and frenzy, vomiting, and frothing at the mouth. The
frothing can be at times bloody. Breathing becomes irregular followed
by convulsions and death in a short time.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
stomach lavage before the contents of the plant are absorbed, treat

YEW


[Illustration: Yew, groundhemlock

_Taxus canadensis, Taxus baccata--TAXACEAE_]

=Description=: The yew, also known as English, Irish, and American yew,
is an evergreen tree or shrub often used as a hedge and found growing
in many gardens or as a decorative plant around homes. Its fruits are
bright red fleshy “berries” borne on the twigs and they frequently
attract children. A large hole sometimes appearing in their ends gives
an appearance of a deep red cup.

=Poisonous Parts=: All parts of the yew are poisonous. Fortunately the
red fruits are the least harmful, although if large quantities are
consumed these too can cause harm. Poisoning may result in nausea,
vomiting, diarrhea, abdominal pain, circulatory failure, and difficulty
in breathing. The poisonous principle includes =taxine=, an alkaloid
which depresses the heart function.

=Antidote=: Call your doctor. Have patient vomit. Physicians perform
gastric lavage and treat for circulatory failure and alkaloid
poisoning.
