Many patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) complain of respiratory distress, chest pain, and arthralgia even after their recovery. We tried to give saibokuto to a 61-year-old man who has suffered from those symptoms as after effects of COVID-19 for more than 2 months. We report that after administration of saibokuto, almost all symptoms have disappeared within 3 weeks.
