Since the start of the COVID-19 pandemic, many individuals have experienced a decline in lung function following infection. Pyunkang-Hwan, a Korean traditional herbal product that focuses on lung cleansing, has recently gained popularity. Dr. Seo Hyo-seok, the developer of Pyunkang-Hwan, recently held a lecture in Canada, explaining how to enhance the body’s self-healing ability through lung cleansing and nurturing.
Wang Shanqing, a patient with chronic obstructive pulmonary disease (COPD) and pulmonary fibrosis who attended the lecture, shared with a reporter from The Epoch Times that over a year ago, he experienced severe coughing, difficulty sleeping at night, fatigue, and occasional wheezing, to the point where he could not catch his breath. After taking ten bottles of Pyunkang-Hwan, his blood oxygen levels increased from 90 or 91 percent to around 96 percent, and his cough has significantly improved.
