In the late 1950s, Boonchua Eiampikul and Tang Leng Yong, two Chinese immigrants who had arrived in Thailand twenty years earlier, met for the first time. Tang Leng Yong – known locally as Master Tang – was a respected practitioner of traditional Chinese medicine. He took Boonchua under his wing as his apprentice and started to teach him all he knew about his trade. Boonchua was a quick study, and Master Tang was impressed with his sincere interest and devotion to the traditional ways of their ancestors. After working together for a while, Master Tang decided that it was time to share with Boonchua one the most effective Chinese medicinal formulas he knew of – a unique kind of herbal mixture that alleviates dizziness and fatigue. Recognizing the importance such a formula could have for the growing Chinese population in Thailand, Boonchua combined his entrepreneurial spirit and business savvy with Master Tang’s traditional knowledge and went to work developing a new product.
