A case of adverse skin reactions to coronavirus disease 2019 vaccine successfully treated with eppikajutsuto

Adverse skin reactions to coronavirus disease 2019 (COVID-19) vaccines have been rare. Because eppikajutsuto (EPTJ), which can alleviate inflammatory swelling, has heatTraditional Medicine module 1 (TM1)-clearing and fluidTM1-regulating potentials, we used it in a case of adverse skin reactions to COVID-19 vaccine. A 35-year-old woman received the second COVID-19 vaccine and presented with hacking, headache, and red glow on the face soon after receiving the vaccine. Symptoms such as flushing and wheal on the upper body improved after treatment with EPTJ. EPTJ can be used to alleviate the symptoms of adverse skin reactions to COVID-19 vaccines.
