A plant dubbed the suicide tree kills many more people in Indian
communities than was previously thought. The warning comes from
forensic toxicologists in India and France who have conducted a review
of deaths caused by plant-derived poisons.
Cerbera odollam, which grows across India and south-east Asia, is used
by more people to commit suicide than any other plant, the
toxicologists say. But they also warn that doctors, pathologists and
coroners are failing to detect how often it is used to murder people.
A team led by Yvan Gaillard of the Laboratory of Analytical Toxicology
in La Voulte-sur-Rhône, France, documented more than 500 cases of
fatal Cerbera poisoning between 1989 and 1999 in the south-west Indian
state of Kerala alone. Half of Kerala's plant poisoning deaths, and
one in 10 of all fatal poisonings, are put down to Cerbera.
But the true number of deaths due to Cerbera poisoning in Kerala could
be twice that, the team estimates, as poisonings are difficult to
identify by conventional means.
Unnoticed homicides
Using high-performance liquid chromatography coupled with mass
spectrometry to examine autopsy tissues for traces of the plant, the
team uncovered a number of homicides that would otherwise have gone
unnoticed. This also suggests that some cases put down to suicide may
actually have been murders, they say.
Although the kernels of the tree have a bitter taste, this can be
disguised if they are crushed and mixed with spicy food. They contain a
potent heart toxin called cerberin, similar in structure to digoxin,
found in the foxglove.
Digoxin kills by blocking calcium ion channels in heart muscles, which
disrupts the heartbeat. But while foxglove poisoning is well known to
western toxicologists, Gaillard says pathologists would not be able to
identify Cerbera poisoning unless there is evidence the victim had
eaten the plant. "It is the perfect murder," he says.
Three-quarters of Cerbera victims are women. The team says that this
may mean the plant is being used to kill young wives who do not meet
the exacting standards of some Indian families. It is also likely that
many cases of homicide using the plant go unnoticed in countries where
it does not grow naturally.
