Bird Flu Fears Mount in China as Herbal Remedies Run Out
A popular herb called ban lan
gen, or blue root, has been flying off pharmacy shelves across China as local
governments encourage people to consider traditional remedies to ward off the latest bird
flu virus.
With scientists so far unable to pinpoint the H7N9 influenza virus’ animal host, locals are preparing for a possible pandemic by stocking up on popular plant remedies as well as face masks and hand sanitizers and other over-the- counter remedies.

Siberia.

“Chinese people associate ban
lan gen with anti-virus,” said Shen Jiangang, assistant director for research at
the University of Hong Kong’s school of Chinese medicine. “So when they hear about bird
flu, they immediately think it might be effective to protect themselves although
there is no experimental evidence.”
Ayurvedic and Chinese medicines have used the remedy for centuries. Scientists have proved it can relieve bacterial conjunctivitis in eye drops and found it has an antiviral effect in test tubes. There is no test to show it works against influenza.
That hasn’t stopped buyers.
Chinese consumers, especially older ones, tend to believe in traditional
formulations especially when it comes to cold and flu remedies, said Iwona
Mamczur, an analyst at Mintel
International Group Ltd. The market for over-the-counter medicines was worth
77.5 billion yuan ($12.5 billion) in 2011, according to a report from
the London-based researcher.
Warm Drink
Ban lan gen is the root of a
flowering plant known as dyer’s woad or indigo woad, and found in southeastern
Europe, central
Asia and eastern Siberia. The roots are dried and often processed into granules,
which consumers ingest dissolved in hot water or tea. According to traditional
Chinese medicine, which seeks to balance heat and cold in the body, the root can
help clear the heat triggered by a viral attack, Shen said.
Huashi Pharmacy, located in Shanghai near the eastern bank of the Huangpu river, has started replenishing supplies of ban lan gen daily instead of weekly and still struggles to meet demand, according to pharmacy worker Zhang Zhijin.
Sales of facial masks have also gone up 10 times from before the H7N9 infections announcements, hand sanitizer has sold out, and companies have been bulk-ordering alcohol wipes for their employees, Zhang said.
Face Masks
Beijing Tongrentang (600085), which
makes a product extracted from ban lan gen, said in an e-mail that the outbreak
of H7N9 has boosted sales, but didn’t provide numbers.
Francis Chu, the Singapore-based
inventor of the totobobo face mask, said he’s fielded more than
20 inquiries about the pollution-filtering equipment’s effectiveness against
bird flu since the start of April. Sales are up eight-fold from the same period
last year.
“Earlier in the year, most of the increased orders from China were because of the air pollution,” Chu said in a telephone interview. “Sales are still increasing, but now it’s because of worries about bird flu.”
Beyond anecdotal evidence, the surge is hard to quantify. Pharmaceutical companies reaped at least $10 billion in sales of vaccines and antivirals globally as a result of the 2009 swine flu outbreak, according to data compiled by Bloomberg at the time. It’s too early to tell whether H7N9 will touch off another pandemic.
No Immunity
Chinese authorities are
struggling to identify the source and mode of transmission of the virus, which
has sickened 77 people and killed 16 so far, most of them in China’s eastern
provinces. While there is no evidence that H7N9 is spreading easily among
people, it hasn’t been detected in humans before, so they have no natural
immunity. That raises public health concerns, researchers at the Centers for
Disease Control and Prevention in Atlanta said last week.
Sinovac Biotech Ltd. (SVA), the first
company to win regulatory approval for a swine flu shot in 2009, is preparing to
make immunizations against the new virus, Chief Executive Officer Yin Weidong
said in an interview Monday. The Nasdaq-traded company could have a first batch
of the vaccine ready for commercial use by late July in the event of a pandemic,
according to Yin.
Until such a vaccine is found, the race is on for Chinese citizens to track down the ban lan gen herb.
Zheng Bing, who works as an assistant at a local private equity firm, recently walked away empty-handed from three separate pharmacies in Beijing’s financial district. Zheng was told by his boss to stock up on the herb for the entire office. But he found that other anxious residents had beat him to the punch.
“I’m going to try a few more shops,” he said. “Otherwise I can’t answer my boss.”
