I developed “Pyun-kang-tang” as a cure for tonsillitis and applied it to my clinical research and prescription for illness. Patients who have tried this medicine claimed that they were not only cured of tonsillitis; they also became psychologically more comfortable. Such cases number more than 3,000. I am reminded of a famous phrase, “心便安而身健康(ShimPyunAnEShin GeonGang),” which means “comfort of heart brings forth physical health.” I used “Pyun” and “Gang” from this phrase (meaning comfort and health, respectively) to name this medicine. “Pyun-kang-tang” was based on my clinical experience and accumulated data from my studies on rhinitis, tonsillitis, and other respiratory troubles, skin problems, freckles and spots, and chronic stomach problems. Curing tonsillitis, rhinitis, and atopic skin troubles by enhancing the body’s immune system, “Pyun-kang-tang” has been used and loved by many people. “Pyun-kang-tang” is manufactured using the most hygienic facilities in Pyunkang Oriental Clinic.
