COVID-19 is caused by SARS-CoV2 and is still not yet under complete control and no cure is available until this moment and it is still unpredictable to expect vaccination in short period. Early diagnosis thus is extreme important. Early identification of loss of smell and taste is of significance in diagnosis of this disease. The aetiologies, pathologies, and mechanisms of loss of smell and taste (LST) are studied, pointing out that disturbed Brain-Shen, dysfunction of the Zang-Fu organs and impairment of the meridians are the key results of LST. TCM management with acupuncture and Chinese herbs are presented accordingly, aiming to establishing some strategies to deal with LST practically and effectively. These unique explanations in the treatment illustrate that although LST is a single symptom, it implies profound and complicated background, which requires a comprehensive treatment in time.
