Thai Herbal Standard is a manufacturer and distributor of traditional herbal medicine, founded in 1995 (B.E. 2538) under the name "Ngam Dee Osot" with registered capital of 400,000 baht in Chonabot District, Khon Kaen. It began as a family business with small machinery and only 5–6 employees.

In 2001 the factory relocated within Chonabot District, Khon Kaen, to expand production capacity and gain more usable space.

In 2013 the business expanded and moved to its current site at 77 Moo 8, Chonabot District, Khon Kaen, and was incorporated as "Thai Herbal Standard Co., Ltd." with registered capital of 1,000,000 baht and assets valued at 10 million baht.

We value human resources — continuously training our staff to build knowledge and skills, creating jobs and income for the community, and improving local livelihoods.

From the very beginning, our founder was committed to producing clean, safe, standardized herbal liquid medicine with the utmost care for consumers, delivered nationwide with a focus on customer satisfaction and on-time delivery.

All of our herbal medicines and other products are certified by the Thai FDA and fully compliant with the law, and are the first GMP-certified products in the Northeast region — so every consumer can be confident that our products are safe.
