Turning the Invisible into a Blade: Network Pharmacology Decodes the Full-Course Wisdom of Aromatic TCM Against COVID-19

In the long history of human confrontation with various novel viruses, the TCM wisdom of "repelling filth and preventing epidemics" has always shone with a unique light. Facing the sudden outbreak of Novel Coronavirus Pneumonia (COVID-19), aromatic traditional Chinese medicines, with their rich volatile oil components, once again transformed into pioneers against the epidemic. This time, network pharmacology has revealed the hardcore scientific mechanisms behind how this "invisible aroma" fights the virus.

When the volatile molecules of aromatic TCM are inhaled or ingested into the human body, they do not fight alone but form a massive and precise "anti-epidemic network." Research has found that these volatile oils contain up to 131 core compounds capable of precisely locking onto 65 key targets in the human body. On this microscopic battlefield, components like palmitic acid and linoleic acid demonstrate an affinity comparable to clinical Western medicines, directly targeting and binding to the "door" through which the virus invades the human body—the ACE2 receptor.

Even more amazingly, the intervention of aromatic TCM is "all-weather and all-around." In the prevention phase, they enhance the body's resistance by regulating immune pathways; during the infection phase, they hit the inflammatory storm directly, effectively inhibiting the spread of lung inflammation by regulating core targets like PTGS1 and JAK1; and in the recovery phase, they can also smooth patients' anxiety and post-traumatic stress through the regulation of central nervous system pathways.

The mechanism of aromatic TCM in preventing and treating COVID-19 perfectly illustrates the deep integration of TCM's "holistic concept" and modern targeted science. This not only provides a brand-new auxiliary treatment strategy for clinical practice but also fills us with awe and hope for the anti-viral codes endowed to plants by nature.
