Mr. Park · Los Angeles
Age 71 · Mild emphysema (smoking history) · 12 months on Pyunkang-Hwan
Five years after quitting smoking, my lung function was still declining year on year. After starting Pyunkang-Hwan, my pulmonologist noted my FEV1 had stopped dropping.
Mr. Park smoked for 25 years and quit after a mild COPD diagnosis in 2018. The diagnosis was a turning point — but quitting alone did not stop the slow downward trend his pulmonologist tracked at his annual check.
The slow decline
Year over year, his FEV1 dropped a little further. His pulmonologist explained that this is the normal trajectory after a long smoking history; the inhaler regimen helped daily symptoms but did not change the slope of the curve.
Mr. Park found this hard to accept. He started reading what Korean medicine had said about lung wellness for the last fifty years.
Adding the formula, alongside his inhaler
He started a 3-month cycle of Pyunkang-Hwan, with his pulmonologist's awareness. He did not change his inhaler. He added a daily 20-minute walk and a humidifier in the bedroom.
First six months
By month three, his cough was looser and his morning energy had lifted. By month six, he was walking 4 km a day. His pulmonologist noted, neutrally, that he looked better than at the previous visit.
One year in
At his annual check, his FEV1 had not dropped. His pulmonologist was careful — one data point is not a trend — but described the result as "the best annual reading we've had in five years." Mr. Park continues 3-month cycles of the formula along with his prescribed inhaler.
