Objective：Fatigue is the most common symptom in post-COVID-19 syndrome. We report the case of a patient with post-COVID-19 syndrome with fatigue treated using herbal medicine (Saengkangsasim-tang).
Methods：A 64-year-old man had severe fatigue for 4 months after a severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection. Saengkangsasim-tang was administered to this patient based on the disease pattern identification diagnostic system by Shanghanlun provisions (DPIDS). We used the Numeric Rating Scale (NRS) and Beck Depression Inventory (BDI) to evaluate the effectiveness of Saengkangsasim-tang for fatigue in the patient with post-COVID-19 syndrome.
Results：According to DPIDS, the patient was diagnosed with the provision 157. After administration of Saengkangsasim-tang for 30days, the fatigue based on NRS and depression based on BDI were improved.
Conclusions：The administration of Saengkangsasim-tang to patients with post-COVID-19 syndrome with fatigue, diagnosed according to the Shanghanlun provision 157, may be effective.
