(HBO) – Born into a farming family, Nguyen Thuy Linh, in Yen Thuy district, soon recognised potential and strength of the locality in planting and preserving precious medicinal herbs, including ca gai leo (scientifically known as Solanum procumbens).

Nguyen
Thuy Linh and her production chain of Solanum procumbens tea.
Solanum
procumbens has been planted in Yen Thuy since 2015 under the second phase of a
poverty reduction project. To meet the increasing demand of the market, in
August 2016, Thuy decided to open a Solanum procumbens tea production facility.
At first, she
produced tea only on office-off days. However, with limited capital investment
and experience, she had met a range of difficulties.
"On the first
days, I went to office in the daytime and read documents on Solanum procumbens
as well as business strategy at night. During weekends, I directly worked with
employees at the facility,” she said.
Her efforts paid
off as in 2017, Linh was eligible to get loans for her start-up project,
allowing her to expand production.
She now owns a
Solanum procumbens tea production facility in Yen Son hamlet, Yen Lac commune,
Yen Thuy district, covering 120 sq.m. Linh signed contracts with local farmers
to plant Solanum procumbens in line with Good Agricultural and Collection
Practices (GACP) standards. She has introduced Binh An Solanum procumbens tea
to the market. With the mixture of Solanum procumbens and Celastrus hindsii and
sweetleaves, Binh An tea has beneficial effects in the prevention and treatment
of high liver enzymes, B and C hepatitis viruses, urticaria, acne, indigestion,
and especially diabetes.
Sweetleaves’
glycoside compounds are 300 times sweeter than sucrose (ordinary table
sugar), thus helping prevent high liver enzymes. Produced from medicinal
plants, Solanum procumbens tea is safe for users.
Linh’s tea
production facility is operating with specialised machines and three workers,
each earning an average of 3-5 million VND monthly.
The product has
been sold in many cities and provinces nationwide like Lao Cai, Yen Bai, Ho Chi
Minh City, Buon Me Thuot, Hoa Binh, Ha Noi, Ninh Binh and Bac Giang, receiving
positive response from customers.
Linh said she
plans to expand tea production to 1ha in order to meet the market’s huge
demand. Apart from purchasing more machines, she will develop a model of
preserving precious medicinal herbs on an area of 6,000 sq.m, at a total cost
of about 5 billion VND.
Hoa Binh province’s economy posted an impressive Gross Regional Domestic Product (GRDP) growth rate of 12.67% in the first quarter of 2025, representing a 12.76% year-on-year increase, the highest rate recorded since the beginning of the current tenure, according to the provincial Statistics Office. This robust growth reflects years of strategic groundwork and sets a strong foundation for the province’s annual growth target of over 10%.
With a focus on cash crop farming with science - technology application and brand building, Lac Thuy district is gradually increasing production value, improving people's life quality, and laying the foundation for sustainable socio-economic development.
In recent years, the economic development model "Hoa Binh Earthworm Farm” run by Mr. Bui Van Dang in Co Giua Hamlet, My Thanh Commune (Lac Son district) has not only brought stable economic value but it is also environmentally friendly, helping to protect and reduce pollution, contributing to the construction of a green and sustainable agriculture.
Dao Village’s honey – a product certified with a 3-star OCOP (One Commune One Product) rating by Thong Nhat Agricultural Cooperative in Dao Village (Hoa Binh City) – is highly regarded by consumers for its quality, richness, and variety in packaging. The distinctively sweet taste of Dao Village’s honey leaves a lasting impression on anyone who has tried it.
In alignment with Project No. 07-DA/TU, issued by the Hoa Binh provincial Party Committee on November 1, 2021, Lac Thuy district has actively promoted investment and supported the sustainable development of its industrial and handicraft sectors during the 2021–2025 period. Alongside this, the district has remained committed to preserving and revitalising traditional craft villages.
Located in the northern part of Lac Thuy district, with a temperate climate and fertile soil, Phu Thanh commune has great potential and advantages in growing tea. The long-standing experience, combined with strict adherence to organic farming practices in the tea gardens, ensures that the dried tea products from Phu Thanh and Lac Thuy as a whole are sold out immediately upon production, providing a stable and prosperous life for the local people.
