Abstract

<p>One of the symptoms of COVID-19 is olfactory dysfunction. Most of them resolve spontaneously at an early stage, but there are some cases that remain as sequelae, and there is no established drug treatment at present. This time, we report two cases of olfactory dysfunction after COVID-19 successfully treated with Kampo medicine centered on kososan. Case 1 was a 32-year-old woman. She was diagnosed with COVID-19 eight months ago, and olfactory dysfunction remained after that. She was yin pattern and slight deficiency pattern, and tenderness was found in the groin. We prescribed her tokishigyakukagoshuyushokyoto. After 8 weeks of administration, she felt warm and well, but her olfaction did not change. Depression due to olfactory dysfunction was also conspicuous, so we administered her kososan in combination. Since then, her olfaction has gradually improved. Case 2 was a 17-year-old man. He was diagnosed with COVID-19 four months ago, and olfactory dysfunction remained after that. He was yang pattern and medium or slight deficiency pattern, and with noticeable signs of qi stagnation. We administered him kososan, and his olfaction has gradually improved.</p>
