A vision that blossomed into a thriving enterprise; a trademark journey that opened up a world of international success. At the turn of the century, Vietnamese husband-and-wife Nguyen Huu Thang and Nguyen Thi Huong Lien – both pharmacists – had a simple yet profound mission: to make herbal products accessible to everyone.
Today, their business “Sao Thai Duong” is thriving with a 1'000+ team of dedicated professionals. The company’s impressive turnover of 32 million US dollars in 2024 is a testament to its success.

Sao Thai Duong has successfully harnessed the Madrid System to grow into more than 55 international markets across Africa, the Americas, Asia, Europe and Oceania.
“The Madrid System has helped us save costs and provided the flexibility to seek trademark protection in multiple countries. I’m truly grateful for the Madrid System. Any business that is looking to expand their business globally should definitely explore the Madrid System!”
