Recent studies and cases have found that patients with Covid-19, whether mild or severe, or even asymptomatic, might leave long-term sequelae, such as fatigue, dyspnea, chest pain or tightness, cough, smell or taste disturbance, memory loss, etc. Persistent symptoms, these sequelae often bring pain and inconvenience to the patient’s life and work, and the recovery time is still unknown.
The achievements of Traditional Chinese Medicine (TCM) in the prevention and treatment of Covid-19 have been affirmed by the public. In the treatment of confirmed patients, in addition to improving clinical symptoms, it can also prevent the disease from becoming critically ill. In terms of treating the sequelae of Covid-19 and restoring bodily functions, TCM also has good advantages.
The main sequelae of the lungs are pulmonary fibrosis that means the lungs are invaded by viruses, and thicker and harder scars appear after tissue repair. TCM treats the lungs and removes blood stasis as the principle. To nourish blood and moisturise, add yang-boosting drugs, such as Polygonum multiflorum, Angelica sinensis, dodder, etc.; if you have qi deficiency and yang deficiency, you could use qi-boosting and yang-boosting drugs, such as astragalus, ginseng, bupleurum, could add radix et rhizoma rhei, almonds, etc., if necessary, which would gradually improve dry cough, shallow breathing, unstable blood oxygen saturation, and fatigue.
For smell or taste disorders, current research shows it might be caused by inflammation and damage caused by the infection of smell or taste-related cells. According to the four diagnostic methods (inspection, auscultation and olfaction, inquiry, and palpation) of TCM, could help gradually restore the original sense of smell or taste by the pungent and cool, pungent and warm, benefiting qi, nourishing yin or tonifying yang Chinese herbs.
In addition, the problem of attention and memory loss (also known as “foggy head”), current research believes that it might be related to the direct or indirect damage to the brain nerves and brain microvessels caused by the virus. Through yang-boosting drugs to help repair the cranial nerves and cerebral microvessels, use the phlegm-resolving drugs to help expel metabolic waste, and it also could add radix et rhizoma rhei, asarum, magnolia biondii and other brain-refreshing drugs to restore original cognitive function.
In addition to trying its best to prevent and treat Covid-19, TCM could also provide appropriate Chinese herbal prescriptions and acupuncture for patients with long-term sequelae to help patients gradually get rid of the residual discomfort and restore normal body functions.
