We report a patient successfully treated with the herbal formulation seihaito for decreased percutaneous oxygen saturation (SpO2) at night. A 90-year-old man was hospitalized for chronic obstructive pulmonary disease post-pneumonia, and the introduction of home oxygen therapy (HOT) was prescribed. He demonstrated dyspnea symptoms mainly at night. On examanination with oximetry for 24 hours, he also showed decreased SpO2 at night. So we administered seihaito without changing his other oral medications. Hypoxemia improved remarkably and the patient showed improvement in ADL. In this case, seihaito may have contributed to clearance of the respiratory tract, and improvement of tracheobronchial change due to the circadian rhythm of this disorder.
