Cordyceps is of the fungi genus that includes about 400species. All Cordyceps species are parasites of mainly insects and otherarthropods, while a few are parasites of other fungi. From late fall toearly winter, the parasites live in pathogens. In summer, whentemperatures rise, the mushroom grows into a plant.
Each month,Hong's workshop produces one tonne of fresh cordyceps, 200kg of driedcordyceps and 1.5 tonnes of powder. Her products are exported to Japan,Singapore and Germany. The cultivation brings an annual revenue of 12billion VND (555,000 USD).
The cordyceps produced at her workshopwere cheaper than the ones imported from Japan and the United States at180 million VND (8,200 USD) per kilogram, while the original productfrom China was worth 1.8 billion VND (82,000 USD) per kilogram, PhamTuan Anh, one of Hong's colleagues, said.
Last year, Hong's workshop started selling cordyceps seeds to people who wanted to plant them.
In2003, after graduating from the College of Hanoi Natural Science'sbiotechnology department, Hong worked for a person who studied severaltypes of fungi.
She read many documents about lingzhi mushroom.
"Oneday, I saw a report in an English newspaper about cordyceps militaris. Ithought it was very interesting," Hong was quoted as saying by TienPhong (Vanguard) newspaper.
Hong began working on the methods of cultivating cordyceps militaris after researching documents for six years.
She asked friends to buy samples from Japan and the Republic of Korea, but could not succeed in planting them.
In 2009, she visited China to buy cordyceps bottles, worth 5 million VND (231 USD), to plant them.
Shestudied the fungi and created a compound that has a structure identicalto the silkworm species with which cordyceps often has a parasiticrelationship.
Unfortunately, she failed to cultivate the crop on a large scale.
Inearly 2012, a strange insect destroyed all 5,000 bottles of cordyceps,worth 300 million VND (13,900 USD). By the end of that year, she plantedmore than 10,000 bottles again, but still failed, losing 600 millionVND (27,700 USD).
Not ready to give up, she studied the causes of her failure.
Tuan Anh, her colleague, went to China, and the Republic of Korea to consult experts about the reasons for fungi death.
Hong herself continued to invest more in research by taking loans from banks, and doing a research course.
In2013, Hong tried to cultivate the fungus in 20 bottles only and thistime, there was no failure. But she failed again when she cultivated on amuch larger scale.
She discovered that the fungus seed she hadbought from China was in poor condition. So she spent 50 million VND(2,300 USD) on another sample.
After creating an artificialenvironment comprising a clean air system, and maintaining moisture andtemperature suitable to cultivation, she succeeded.
Despite her success, no one believed her product was true cordyceps.
Hong offered her product for free to some people for two years to gain wider acceptance.
Now her products are sold in the market and have received positive feedback.
Cordycepsis used to treat several diseases, apart from being used to strengthenthe immune system, improve athletic performance, reduce the effects ofaging and promote longer life, besides improving liver function inpeople with hepatitis B.
Its value as a medicinal mushroom is much more than gold due to its unique healing qualities.-VNA
