People who have the novel coronavirus disease 2019 (COVID-19) usually recover completely within a few weeks. But some people, even those who had mild versions of the disease, continue to experience symptoms after their initial recovery. These post-COVID-19 symptoms (Long COVID) is a sequala of the imbalance of Ying and Yang, which includes loss of sense of smell, mental dullness, depression, anxiety, palpitations, fatigue, shortness of breath, vertigo, headaches, insomnia, musculoskeletal pain, or disorders of the nervous system. Studies have shown that Long COVID can involve multiple organs and systems. From the perspective of Traditional Chinese medicine, these symptoms resulted from the initial attack of exterior evil (pathogen), leading to the internal damage of viscera and bowels and imbalance of Yin and Yang. To ameliorate Long-COVID symptoms, it is therefore very important to harness Ying and Yang to resume the harmonious balance. In this lecture, we will discuss the followings:
