RECENTLY, a little known leaf
allegedly used by addicts to complement their craving habits was thrust to fame.
It is the ketum leaf, also known locally as daun biak.
The leaf is mainly found in the northern part of the country and in neighboring
Thailand, where it is called Kratom.
Scientifically the plant is identified as Mitragyna speciosa Korth, a tree of
about 30 metres tall, with dark shiny green leaves and yellowish coloured flower
(for pictures see:
Erowid's
Kratom Images). It contains an active
compound called mytragynine, said to have a simulating and/or sedative effects
on the brain. It is this effect that is causing concern among some people and
the authorities. Some have equated the effects to that of ganja and even
morphine. But there is no convincing evidence regarding this. It looks like
daun biak is in a class of its own.
Studies conducted at the Universiti Sains Malaysia indicated that the active
compound can also cause effects like dryness of mouth, constipation, loss of
appetite and increased urination. Some of these effects could be useful in
medical treatment but others could be regarded as harmful effects. There were
also reports that some of the effects can lead to some addiction, though users
are usually not rendered unproductive, unlike other drug addiction.
According to some herbalists however, the plant is not all bad. For decades some
documented traditional uses include reducing body temperature, for de-worming,
diarrhoea and cure for stomach ailments. An Internet source suggests that it
could also be used to treat high blood pressure, diabetes and for tiredness.
Like all other traditional plants with many potential uses, pokok biak is
legally grown; in some cases an ornamental tree. Given the recent spate of
events, it is possible that this will change if the authorities decide to ban
it. Others insist that the plant be immediately chopped down and destroyed which
could mean a loss in our biodiversity, especially when the species is uniquely
found in this part of the world.
But there is an extreme irony in all these hue and cry when one considers
another, no less controversial, leafy plant locally known as tembakau or
tobacco.
Like the biak, tembakau is also legally grown and consumed. More
importantly both are addictive and could endanger health. The difference is,
tembakau is evidently more hazardous than biak.
For example, tembakau has been documented to cause other serious and
harmful effects, namely a variety of cancers, especially lung cancer, the major
cause of death of tobacco-related disease. It can also cause serious
cardiovascular disease and high blood pressure, yet another cause of death. When
smoked the fume released is equally deadly.
More than the addiction associated with tembakau is likened to that of
cocaine and heroin. This is not the case for biak.
Despite all these, most ironic of it all is the way tobacco commands respect in
this country. For example, rather than calling for its destruction, the
authorities seem to be protecting the tembakau plant and the industry
based on it. Nationwide, more than 15,750 hectares of land are being planted
with this obnoxious plant, and the produce subsidised. Just late week, tobacco
producers got a major boost in the form of a RM22.5 million special credit
assistance from the government.
This is expected to increase production to no less than nine million kilogrammes
this year, translated to mean millions of tobacco-related deaths.
So why the preoccupation with biak, if the even more dangerous
tembakau is given so much protection. What justification can we offer to ban
and destroy the sparsely grown biak, mostly wild, when thousands of
hectares of tobacco plant are being cultivated. Some may cite that the Thais
have banned biak, and that we should follow suit. Unknown to many
however, Thailand too has a very tightly regulated tobacco market. Should we not
consider emulating this first? Moreover, so far there is no known biak
related death documented in this country compared to the millions attributed to
tobacco. If it is the health of our citizens that we are trying to protect then
we should get our priority right. Whatever is decided for biak, the same
treatment must be accorded to tobacco simultaneously. Lest we look a nation of
fools!
