This is an extremely important and core question. Regarding the effectiveness of TCM, it cannot be simply answered with "effective" or "ineffective"; it needs to be analyzed from a scientific and objective perspective.
In general: TCM is effective, but its effectiveness is based on the principles of "syndrome differentiation and treatment" and "rational use". At the same time, we must acknowledge that in the context of modern scientific discourse, there are areas requiring in-depth research and communication between TCM’s effectiveness verification methods, mechanism of action, and traditional experience.
The following is a detailed analysis from different perspectives:
1. Historical and Practical Evidence (Diachronic Verification)
The strongest support for TCM comes from its thousands of years of clinical practice and historical verification. TCM has made an indelible contribution to the survival and prosperity of the Chinese nation. Countless people, both in history and modern times, have treated diseases and improved their health through TCM.
Examples: The use of Artemisia annua (the source of artemisinin) to treat malaria, the use of Tripterygium wilfordii (a TCM herb) as a treatment for leprosy, and the use of arsenic trioxide (from TCM formulas) to treat acute promyelocytic leukemia—all of these drew inspiration from TCM prescriptions and have been confirmed by modern medicine.
Logic: A theoretical system that is completely ineffective cannot survive for thousands of years without being eliminated. Its continuity in itself proves its value to a certain extent.
2. Modern Scientific Research (Biomedical Verification)
With the development of science and technology, more and more studies have begun to use modern scientific methods to verify the effectiveness and safety of TCM.
• Extraction of active ingredients: The active ingredients of many TCM herbs have been isolated and identified, and their pharmacological effects have been clarified. The most famous example is artemisinin (extracted from the TCM herb Artemisia annua by Tu Youyou, who won the Nobel Prize), which is used to treat malaria.
• Pharmacological research: Studies have found that berberine (from the TCM herb Coptis chinensis) has significant antibacterial and anti-diarrheal effects; ginsenosides (from ginseng) have anti-fatigue and immune-regulating effects.
• Clinical randomized controlled trials (RCTs): An increasing number of high-quality clinical studies have shown that certain TCM formulas, when used alone or in combination with Western medicine, exhibit good efficacy and safety in treating specific diseases (such as chronic gastritis, coronary heart disease, adjuvant treatment of diabetes, and certain gynecological diseases).
3. Holistic View and Syndrome Differentiation (Unique Thinking Mode)
This is the core key to TCM’s effectiveness and also the biggest difference between TCM and modern medicine.
• Not "treating the head when the head aches": TCM does not focus on direct confrontational thinking such as "reducing inflammation" or "killing bacteria". For example, in the case of infectious fever, TCM practitioners may not only use heat-clearing and toxin-resolving herbs but also, depending on the situation, use methods like "relieving constipation" (e.g., with Rheum palmatum) or "inducing sweating" (e.g., with Ephedra sinica) to provide an exit for pathogenic factors, thereby reducing fever.
• Individualized treatment: TCM prescriptions are usually compound formulas, with multiple herbs used in combination (following the "monarch-minister-adjuvant-guide" principle) to work together. TCM practitioners prescribe different formulas based on each person’s specific constitution, symptoms, tongue coating, and pulse condition (i.e., "syndrome type"). This is why people with the same disease may take different medicines. This highly individualized treatment model is difficult to perfectly verify through the "one-size-fits-all" large-scale clinical trials of modern medicine, but it is precisely the essence of TCM.
4. Challenges and Misconceptions to Face Squarely
While affirming the effectiveness of TCM, we must also clearly recognize the challenges it faces and common public misconceptions:
• The biggest misconception: "TCM is all-natural, so it has no toxic side effects!" This is completely incorrect. TCM herbs are medicines and have "bias" (a TCM term referring to their specific properties). Improper use can lead to toxic side effects. For example, Aristolochia manshuriensis (containing aristolochic acid) can cause renal failure, and improper use of Polygonum multiflorum can damage the liver. TCM must be used under the guidance of professional practitioners.
• Unclear mechanism of action: For many compound TCM formulas, we know they are effective, but why are they effective? Which ingredient plays the main role? How do multiple ingredients synergize or antagonize each other? Many of these mechanisms are still unclear and require further research using modern scientific methods.
• Uneven quality of medicinal materials: TCM herbs are agricultural products. The content of their active ingredients is greatly affected by factors such as origin, planting methods, harvesting season, and processing techniques. Their quality is difficult to standardize like chemical drugs, which can affect the stability of efficacy.
• Lack of high-quality clinical evidence: Although there are more and more clinical studies, compared with Western medicine, many TCM formulas still lack evidence from large-scale, multi-center, double-blind randomized controlled trials. This limits their recognition in the modern evidence-based medicine system.
Conclusion
There is no doubt that TCM is effective. Its effectiveness is rooted in thousands of years of practice and is increasingly being confirmed by modern science.
However, its effectiveness is highly dependent on "correct use":
• For doctors: They must be proficient in TCM theory and accurately differentiate syndromes.
• For patients: They must abandon wrong concepts such as "folk remedies cure serious diseases" and "TCM has no toxicity", strictly follow the guidance of professional TCM practitioners, and never prepare or take medicines on their own.
Combining the advantages of TCM’s holistic view and syndrome differentiation with the rigorous research methods of modern science is the correct direction for verifying and developing TCM in the future.
