About us
From a Small Herbal Pharmacy to a Leader in Thai Herbal Industry.
Founded in 1947, Ouay Un Dispensary Co., Ltd. is a trusted Thai herbal company with over 200 SKU of products, ranging from Thai traditional and Chinese traditional medicines manufactured under GMP PIC/S certification, and GMP certified herbal food supplements.
Ouay Un Dispensary is a Thai herbal medicine manufacturer with a long and distinguished history spanning more than 79 years. The company was founded on the foundation of Thai traditional medicine and Chinese herbal practices by Mr. Sathien Somboonvechakarn, a Thai Traditional Medicine practitioner who began his work by formulating herbal remedies focused on real-world effectiveness and patient safety. This body of knowledge has been carefully passed down and continuously developed across generations, shaping Ouay Un into an organization that systematically integrates traditional wisdom with modern science and innovation. Guided by the philosophy of “Innovation through Tradition,” the company aims to ensure that Thai herbal medicine remains relevant and responsive to contemporary health needs.
One of the key strengths of Ouay Un as a manufacturing establishment lies in its ability to develop herbal products based on deep expertise in pharmaceutical production, combined with internationally recognized manufacturing standards. The company is certified under GMP PIC/S, emphasizing not only product quality and consumer safety but also occupational health, workplace safety, and the prevention of environmental and community impacts. As a result, Ouay Un’s production processes do not merely focus on output volume, but prioritize quality control from raw materials through every stage of manufacturing to finished products, ensuring consistency, traceability, and reliability for consumers.
Another distinctive feature of the organization is its work culture, which actively encourages creativity and cross-disciplinary learning. The Ouay Un team comprises experts in Thai traditional medicine, food science, manufacturing, quality control, and product design, all working collaboratively in an integrated manner. The company places strong emphasis on experimentation, continuous product development, and improvement based on real user feedback. This approach has enabled Ouay Un to consistently deliver health innovations that address genuine market needs—ranging from upgraded traditional remedies designed for greater ease of use, to entirely new products that establish new benchmarks within the Thai herbal industry. Consequently, Ouay Un is not only a medicine manufacturer, but also an organization that plays a vital role in advancing Thai herbal medicine toward sustainable health innovation at both the national level and beyond.
