When ancient wisdom meets modern medicine, the results can be revolutionary.
When COVID-19 swept across the globe, healthcare systems scrambled for effective treatments. In China, where Traditional Chinese Medicine (TCM) has been practiced for thousands of years, doctors combined ancient herbal remedies with conventional Western medicine, reporting remarkable results. But what does the scientific evidence say? We analyze multiple systematic reviews and meta-analyses to separate fact from fiction in this fascinating convergence of healing traditions.
Traditional Chinese Medicine has been used to prevent and control infectious diseases in China for thousands of years, with documented success against epidemics including plague, cholera, and smallpox 1 . More recently, TCM played significant roles in combating SARS, AIDS, and H1N1 influenza 1 .
Chinese herbal medicine takes a different approach from Western medicine. Rather than targeting specific pathogens directly, it focuses on strengthening the body's own defense systems and creating an internal environment that's less hospitable to invaders 8 .
According to TCM theory, COVID-19 belongs to the category of "plague," primarily characterized by "dampness" that settles in the lungs 1 .
During the COVID-19 pandemic, the Chinese government actively promoted the integration of TCM into standard care, with the combination of Chinese herbal medicine and conventional Western medicine being used in approximately 92% of diagnosed COVID-19 cases in China 2 .
Multiple systematic reviews have synthesized findings from dozens of clinical trials to evaluate whether combining Chinese herbal medicine with conventional Western medicine produces better outcomes than Western medicine alone.
A 2023 analysis published in Frontiers in Medicine examined 50 randomized controlled trials involving 11,624 patients 2 . The results were striking across multiple dimensions of COVID-19 recovery.
| Outcome Measure | Improvement with Combined Therapy | Significance Level |
|---|---|---|
| Clinical Effective Rate | 18% higher (RR=1.18) | P<0.05 |
| Mortality Reduction | 47% lower (RR=0.53) | P<0.05 |
| Progression to Severe Disease | 55% lower (RR=0.45) | P<0.05 |
| Chest Image Improvement | 19% higher (RR=1.19) | P<0.05 |
| Adverse Reactions | No significant difference | Not significant |

To understand how researchers are studying this integrative approach, let's examine how these systematic reviews are conducted—using the 2023 meta-analysis as our exemplar 2 .
Researchers systematically searched eight electronic databases and three clinical trial registries, covering publications from January 1, 2020, to May 18, 2023 2 . The search included both English and Chinese databases to minimize language bias.
Only randomized controlled trials (RCTs) comparing Chinese herbal medicine plus conventional Western medicine against conventional Western medicine alone were selected. Studies needed to include confirmed COVID-19 patients regardless of disease severity 2 .
Teams of independent reviewers extracted data using standardized forms and assessed methodological quality using the Cochrane Risk of Bias tool 2.0 2 . This rigorous approach helps ensure the reliability of the findings.
Researchers used sophisticated statistical methods to combine results from multiple studies, calculating pooled effect sizes for various outcomes including clinical effective rate, mortality, symptom recovery times, and adverse events 2 .
The analysis revealed that the benefits of combined therapy were consistent across multiple studies, despite variations in the specific Chinese herbal formulations used 2 . The safety profile of combined treatment was particularly noteworthy, with no significant difference in adverse reactions between the combined therapy and Western medicine-only groups 2 6 .
| Symptom | Reduction in Recovery Time | Number of Studies Analyzed |
|---|---|---|
| Fever | 1.1 days faster | 22 studies 8 |
| Fatigue | 2.28 days faster | 22 studies 8 |
| Cough | 2.63 days faster | 22 studies 8 |
| Dyspnea (Breathlessness) | Significant improvement (SMD=-1.64) | 22 studies 8 |

Through extensive research, several Chinese herbal medicines have emerged as particularly promising against COVID-19. These formulations have been recommended by Chinese health authorities and studied in clinical trials 2 7 .
Form: Decoction/Granules
Primary Functions: Eliminates dampness, clears lung heat
Form: Capsules
Primary Functions: Disperses wind-heat, clears toxins
Form: Granules
Primary Functions: Clears heat, relieves surface
Form: Injection
Primary Functions: Activates blood, resolves stasis
Form: Pills/Oral liquid
Primary Functions: Resolves dampness, harmonizes stomach
Modern pharmacological research has identified potential mechanisms through which these herbal medicines may combat COVID-19, including anti-inflammatory effects, antiviral activity, and immunoregulation 8 . Some active ingredients in TCM formulations have been found to target key proteins of SARS-CoV-2, such as Mpro (the main protease) or ACE2 (the cellular receptor for the virus) 8 .
An important consideration with any treatment is safety. Reassuringly, the systematic reviews found that the addition of Chinese herbal medicine to conventional treatment did not significantly increase adverse events 2 6 9 . The adverse reaction rates were similar between combined therapy and Western medicine-only groups, suggesting that the integrated approach has a comparable safety profile to standard care 2 .
However, researchers note several limitations in the current evidence base. Many studies had methodological limitations, and the certainty of evidence was generally graded as low to moderate 2 . Additionally, most trials were conducted in China, raising questions about generalizability to other populations 8 .
The promising results from these analyses have implications beyond the current pandemic. They suggest a potential model for addressing future viral outbreaks through the integration of traditional and modern medical approaches.
Research continues to evolve, with recent studies exploring the role of Chinese herbal medicine in addressing long COVID symptoms and COVID-19 patients with comorbidities 7 . Early evidence suggests TCM may help with persistent symptoms such as fatigue, chest tightness, and insomnia .
As one meta-analysis concluded, "TCM may potentially support the standard treatment of COVID-19" 8 . While more high-quality trials are needed to establish optimal protocols, the current evidence suggests that the combination of Eastern and Western medical approaches could offer a more comprehensive strategy for combating COVID-19.
