ABSTRACT
Coriaria Myritfolia is a shrub that grows 2
-
3 meters tall. The exact local
n
ame of the plant is unknown, but in Hindi, some species of Coriaria are
called “Divi
-
Divi”. We report a case of intoxication following ingestion of
fruits of Coriaria Myritfolia. A 6
-
year
-
old boy, the previously healthy child,
was brought to the pediatric
emergency department after accidentally
ingesting red berries from a tree growing wild in district Haripur. On
inquiry, the parents of the child reported that after the ingestion of an
unknown quantity of fruit, the child felt nauseated and vomited. We so
ught
care from a local Physician who treated the outpatient as a case of food
poisoning. The child didn’t get better and, after 4
-
6hr from the ingestion of
berries, felt a generalised
-
tonic
-
clonic seizure with up rolling of the ball and
incontinence. The p
arents immediately brought the child to a tertiary care
hospital. Upon arrival at the hospital, the patient was somnolent with
generalised hypotonia. The Prophylactic 10mg Diazepam (0.4mg/kg) is given
per rectal. The peripheral intravenous line passed. Ini
tial labs were not
conclusive except for hypokalemia and metabolic acidosis. He was started on
the prophylactic antiseizure elixir of Phenobarbital 5mg/kg/day and
levetiracetam 400mg/ day. CT brain was normal. The patient was discharged
after 3
rd
day of ad
mission on anti
-
seizure medications. We concluded that the
intoxication with the fruits of Coriaria Myritfolia could be managed
successfully if the patient came to the hospital within 6
-
8 hours with anti
-
seizure medications.

INTRODUCTION
Coriaria myrtifolia is known by a variety of different
names; it is also called sweet poison due to its sweet
berries; it produces reddish, attractive, shiny berries
which are love
ly. Africa criteria is commonly known as
Redoul or Redoulin in Europe and North Africa
-
the
most common name used in botanical and horticulture
context.

In America and the Caribbean, this plant is
known by the name Divi
-
Divi. The name divi
-
divi
originated
from Hindi, which means - to split . Khyber
Pakhtunkhwa is commonly known as Nagar or Nagari,
while in some areas of Pakistan, it's known as
Kharay.
2,3
Coriaria myrtifolia is a 2
-
3 meters tall shrub
found in the Himalayas, usually between 1000
-
2500
meters a
bove sea level. This plant is distributed in some
areas of all provinces of Pakistan. In Khyber
Pakhtunkhwa, the common areas where this shrub
grows and is found are Swat, Dir, Malakand, Buner,
Shangla and Kohistan. Both the leaves and the fruit
contain a
neurotoxin called coriamyrtin and
didehydrocoriamyrtin.
3,4
These toxins have multiple
actions on neurons; these toxins inhibit acetylcholine
esterase (AChE), which in return increases the level of
acetylcholine in the brain. Coriamyrtin also has
antagonist
ic activity on GABAA receptors.

We report
a rare case of coriaria myrtifolia, which gets
complicated by brain toxicity. The case was managed
successfully in the emergency department of Ayub
Medical Teaching Institute Abbottabad.

brought to the pediatric emergency department after
accidentally ingesting red berries from a tree growing
wild in district Haripur. The family bring the branch of
the shrub shown in figure 01. On inquiry, the pare

the child reported that after the ingestion of an unknown
quantity of fruit, the child felt nauseated and vomited.
We sought care from a local Physician who treated the
outpatient as a case of food poisoning. The child didn’t

seizure with up rolling of
the ball and incontinence. The parents immediately
brought the child to a tertiary care hospital. Upon
arrival at the hospital, the patient was somnolent (GCS:

3, V4, M5), generalised hypotonia, but the
hemodynamic status was good. The weight of the baby
was 25 kg at presentation. The Prophylactic 10mg
Diazepam (0.4mg/kg) is given per rectal. The peripheral
intravenous line passed. Appropriate labs were ordered,
including Complete blood count, blood sugar, and
electrolytes, including calcium. The patient felt another

episode of seizures, which was aborted with 2.5mg (100
microgram/Kg) of intravenous midazolam diluted in
5cc normal saline. The patient was admitted
to the
pediatric unit. The nasogastric tube was passed, and air
was placed in the mouth. He was started on a
prophylactic antiseizure elixir of Phenobarbital
5mg/kg/day (Elixir Debritone 20mg/5ml) and oral
solution of levetiracetam 400mg/ day in 2 divided
doses
(syrup race 100mg/ml). The serum chemistry shows
calcium of 7.8 mg/dl, sodium of 129mg/dl, potassium
of 2.8mg/dl and chloride of 98mg/dl. The Atrial blood
gases show a PH of 7.30, HCO3 of 19mg/dl, oxygen of
75mmof hg and CO2 of 42mm of Hg. The finge

glucometer shows a reading of 5.5 milli mole. On the
next day, the brain CT was ordered to rule out an
intracranial lesion, which also turned out to be
expected. The patient was oriented to time and place,
and his oral intake improved, but he comp

perioral numbness and flickering movements in the
facial muscles. His chewing strength was expected, and
the cranial nerves were intact. The rest of the
examination was unremarkable. The patient was
discharged after 3 days, and a follow

de after
4 days. The patient was continuing on antiseizures for 4
days. On the follow

up visit, the patient’s examination
was regular. No adverse event was noted. The syrup

DISCUSSION
Coriaria myritfolia is a shrub which bears fruit (toxic
berries) from June to September. The child usually
confuses the berries of criteria with other edible berries,
so poison i
s common in the young age group.
5,6
Both
the leaf and fruit intoxication are reported in the
literature, but in our case, intoxication occurs due to
fruit. The toxic dose is not quantified precisely, but 2
-
3
berries are enough to produce the neurological
s
ymptoms and can require admission to the hospital.
4
Some studies have suggested that intoxicated chemical
decreases the GABA levels in the brain, which leads to
seizures.
7,8
Children are the most common victims of
this plant because its berries (fruit) ar
e attractive,
charming and sweet; hence, it is also called sweet
poisoning. We observe only seizures as a neurotoxicity
of Coriaria, while other studies also reported trismus,
opisthotonus, apnea and coma.
4
In this case, we
successfully treated the neuroto
xicity with Diazepam,
Phenobarbital and levetiracetam. In a case reported by
de Haro L et al., an intoxication of 8 years old child was
treated successfully with benzodiazepine. In a letter to
the editor by Yen
-
Chin Chen, he reported the successful
treatme
nt of 2 such cases with diazepam. Our case
delineated the neurological toxicity of Coriaria species,
which is potentially life
-
threatening if it cannot be
intervened in a timely. We provided the details of local
names, geographical areas, and pictorials t
o identify
them earlier and help the emergency physician identify
poisonous plants early.
LIMITATIONS
This report is limited by the lack of confirmatory
toxicological analysis, reliance on clinical presentation,
and absence of long
-
term follow
-
up. Furthe
r studies are
needed to establish standardized management protocols.
CONCLUSIONS
The delayed toxicity of sweet poison led to an
imbalance in neurotransmitters in the brain. This led to
seizure genic activity in the brain, which could lead to
irreversible
brain damage, especially in young children.
The fruit(berries) is toxic, and 2
-
3 can produce harmful
effects. Patients should be admitted after intoxication
because the neuronal side effects are delayed. Early
management within 6
-
8 hours can prevent furth
er
seizures and permanent brain damage.
