Since the confirmation of the first H7N9 infections in China, dozens of new cases have appeared, and 16 people have already died from this new strain of avian influenza or bird flu. Local health authorities all around in the country are on high alert to prevent the infection from spreading.

At the same time, provincial health authorities are also busy trying to quell any public panic by recommending ways to prevent people from being infected. One of the main antidotes that they suggest is for people to cook up a brew of a herbal remedy called banlangen (板蓝根) or Indigowoad Root, which, as the name suggests, is derived from the root of a plant called woad.

Banlangen was also the drug-of-choice for preventing the 2003 SARS epidemic as well as the 2005 foot-and-mouth disease outbreak. This time, not only is everybody taking banlangen, it's also being fed to chickens and other birds.

We can understand the original intention of local health authorities in recommending this preventative measure. To limit the panic caused by a new avian flu outbreak, relevant government departments have to act and inform the public in the most efficient way possible. However, the solution they advocate has garnered public ridicule and contempt – which has defeated its original purpose.

One thing is certain, it's that anyone with a bit of common sense should know that banlangen is not a magic cure-all – there is no such thing. So why are officials so obsessed with banlangen and why have they been promoting it as some kind of magic pill for more than a decade?

To put it plainly it's because the authorities believe that the public needs a placebo. Even if it has no real effect, it can at least bring psychological comfort – better to have it than to go without.

Unproven Cures

It is true that banlangen has antiviral properties, but its effect on the H7N9 virus has yet to be clinically proven. There is absolutely no scientific evidence to support the fact that using this drug can be helpful to ward off a pandemic. Not to mention that there have been a lot of adverse reactions to long-term us of banlengen recorded –including digestive tract problems and liver damage.

Banlangen is not the only unproven drug recommended by the health authorities. This government department, which is supposed to rely on science, shouldn't be so un-scientific in its recommendations.

This is very ironic coming from a government that has been trying to raise scientific awareness for years, to promote the scientific literacy of its population.

Do people need placebos? Of course they do. But the most effective way to quell a public panic is to set up a system so that information is more transparent. A system that explains to the public what the real situation is, what the government is doing about it and what the public should be doing.

Alas, far too often, the Chinese government is not transparent in the way it informs the public, whether in responding to a pandemic or other incidents.

Sometimes the authorities are so casual that their reaction leads to an even bigger panic and misunderstanding. Case in point, the public frenzy to stock up on banlangen.

One of the adverse effects the herbal remedy has had is that it undermines the professional work of Chinese health authorities.

In contrast, the World Health Organization's guidelines for warding off the flu seem much more reasonable. Their website lists various ways of prevention infection, including hand and respiratory hygiene and staying away from dead or diseased animals.

It is worth noting though, that compared to ten years ago when the SARS epidemic killed nearly 800 people in China, the ministry of health has made significant progress in communicating with the public and disclosing information.
