Traditional medicine is the total of knowledge, skills, and practices based on theories, beliefs, and experiences indigenous to different cultures, used to maintain health and prevent or treat illness. According to the World Health Organisation, an estimated 88% of all countries still actively utilise traditional medicine. It encompasses diverse systems firmly rooted in specific global regions.
Traditional Chinese Medicine (TCM) and Acupuncture are widely practised across East Asia and increasingly integrated globally. Ayurveda, Unani, and Siddha are popular predominantly in South Asia (India, Bangladesh, Nepal). Kampo is fully integrated into the modern healthcare system of Japan. Traditional African medicine is relied upon by up to 80% of rural populations in Africa for primary healthcare, and native american and indigenous herblore is maintained throughout the Americas. These types of therapies are very old (see figure below).
Adopted from different sources
Today, these systems coexist with conventional medicine, forming a foundational pillar of global primary healthcare. In this article, I will discuss acupuncture, a millennia-old practice and a core component of TCM. Nowadays, it is being scrutinised through the lens of modern science.
History of TCM
The historical narration of TCM is a story of continuous development, cultural exchange, and adaptation spanning over three millennia.
Ancient Foundations
The earliest evidence of acupuncture, in the form of sharp stones, dates back to around 1000 BC during the Shang dynasty. The theoretical framework for TCM was first laid out in the Huangdi Neijing (The Yellow Emperor's Inner Classic) around 206 BC during the Han dynasty.
Golden Ages and Global Exchange
Different aspects of TCM have waxed and waned in importance. Herbology flourished in the 14th and 15th centuries, while acupuncture reached a golden age during the Ming dynasty (16th-17th century). The Silk Road played a crucial role in TCM's global journey, facilitating the export of herbs to Persia and Rome and spreading TCM texts to Japan and Korea.
Modern Era and Global Recognition
TCM faced challenges in the 1920s when it was banned in China, but was revived after 1949. The modern breakthrough for TCM in the West is often attributed to President Nixon's 1972 visit to China, which sparked widespread international interest in acupuncture. More recently, the World Health Organisation recognised TCM in 2019, and today, over 100 countries have adopted acupuncture and herbal clinics.
The Scientific Basis, Safety, and Mechanism of Acupuncture
This is where ancient practice meets 21st-century science. The effects of acupuncture are no longer seen as mystical but as a series of measurable physiological events.
How Acupuncture Works: A Physiological Framework
Acupuncture is best understood as a form of neural stimulation. Inserting a needle into a specific point on the body creates a small, localised stimulus that triggers a cascade of effects in the central and peripheral nervous systems.
Neuroanatomical Basis of Points
Modern research suggests that classical acupuncture points and meridians closely correspond to anatomical features like nerve bundles, blood vessels, and fascial planes (the connective tissue that surrounds muscles). These are areas of high physiological activity, making them particularly responsive to stimulation.
The Deqi Sensation
The therapeutic sensation called deqi, described as a dull ache or pressure, correlates with the activation of specific sensory nerve fibers (See article by Hui et al. 2010 for details).
The Scientific Mechanism of Acupuncture: A Detailed Look
When a needle is inserted, it does not unblock energy but instead initiates a verifiable chain reaction:
Brain Modulation (Central Nervous System)
This is the most significant scientific finding. Functional MRI (fMRI) studies show that acupuncture does not just activate the sensory cortex (the touch area of the brain). Instead, it strongly modulates the limbic system and paralimbic structures, which are the brain's centres for pain perception, emotion, memory, and the stress response.
Neurotransmitter Release
Acupuncture stimulates the release of the body's natural painkillers: endorphins and enkephalins (opioid peptides). It also influences other key neurotransmitters like serotonin and norepinephrine, which play crucial roles in mood regulation and pain processing.
Physiological Effects
The cascade of neural and chemical events leads to tangible outcomes, including:
- Improved local circulation, delivering oxygen and anti-inflammatory agents to tissues.
- Activation of the parasympathetic nervous system (the rest and digest branch), which counters the stress response and promotes healing.
Is it simply a Placebo?
This is a critical and active area of research. The answer is no, the benefits are not simply a placebo, but the placebo effect is a significant component.
Evidence for Specific Effects
Large-scale analyses of many clinical trials have consistently shown that real acupuncture is statistically more effective than sham (placebo) acupuncture for treating chronic pain. This small but real difference indicates a specific physiological effect beyond expectation. This is why a network meta-analysis found that a waiting list group (which received no treatment) showed a significantly more pronounced perceived difference in pain relief compared to the real acupuncture group than any of the sham groups did.
The Sham Controversy
The placebo effect in acupuncture is powerful, which means that a sham procedure (like using a retractable needle that doesn't penetrate the skin) often provides significant relief on its own. However, the least placebo effect among sham methods is observed with non-penetrating needles, making them the preferred control. The mere act of a clinical ritual and patient expectation (the placebo effect) can account for a large portion of the benefit, but it does not explain all of it.
Safety Profile
When performed by a qualified, trained practitioner using sterile, single-use needles, acupuncture is a low-risk procedure. Systematic reviews conclude it is "at least as safe or safer than usual care" for many conditions.
- Common Side Effects: Minor, self-limiting events like localised pain, slight bruising, or temporary dizziness.
- Serious Side Effects: Rare, but include organ or nerve injury (e.g., pneumothorax, or a collapsed lung, from needling too deep on the chest) and infections from non-sterile technique. These are largely preventable with proper training and hygiene.
Success stories of acupuncture
While clinical trials provide the statistical evidence for acupuncture's efficacy, individual patient stories offer a powerful, human-scale view of its potential impact. Here are several success stories for chronic back pain and migraines, drawn from recent medical case studies and news reports.
Chronic Back Pain: Real Patient Journeys
For patients with debilitating back pain, acupuncture has, in some cases, provided a path away from strong painkillers and helped them return to daily activities.
Kym's Story: From Fracture to Holding Her Grandson
Kym, a 62-year-old, suffered a vertebral fracture that caused excruciating pain, leaving her unable to turn her neck, stand for long, or even hold her grandson. Skeptical but desperate, she tried acupuncture as part of her physiotherapy. Her physiotherapist, Cecelia James, used acupuncture as a key part of her treatment plan. After just her first session, Kym felt she could move again. The most significant result was that she was able to stop taking strong opioid painkillers like Morphine and Tramadol. While she still experiences some pain, it is now manageable, and she has regained her quality of life.
A Patient's Detailed Progress: Tracking Pain Reduction
A female patient in her 70s was diagnosed with spinal stenosis and a disc herniation after a fall. The pain was so severe at times that she couldn't get up. The patient came to a clinic seeking a non-surgical, curative treatment. She received an injection treatment (the Cellgel method) combined with a personalised acupuncture and rehabilitation plan, which she diligently followed at home for an hour daily.
She tracked her own progress on a scale of 0 to 10. Before treatment, her lower back pain was a 7. One week after treatment, it dropped to a 4. After six months, her pain and numbness had reduced to a 1 or 0. She reported that her symptoms suddenly became less severe and she started feeling better.
Diane's Journey: Restoring Mobility
Diane suffered from degenerative scoliosis and spinal stenosis, which had severely limited her mobility. Surgery was not an option for her. She turned to acupuncture after finding limited success with standard medical treatments. Week by week, Diane progressed from struggling to walk to standing tall again. She was thrilled to return to her hobby of quilting, stating, "I think it’s a miracle. I haven’t taken aspirin in months".
Migraine Relief: Patient Experiences
For migraine sufferers who have not found relief through conventional medicine, acupuncture has proven to be a life-changing alternative.
Jordan's Story: A Teenager Regains Her Life. Jordan, a 16-year-old athlete, began having debilitating migraines at age 7. They would strike up to three times a week, causing her to vomit, miss school, and be unable to stand. After trying medications and lifestyle changes without success, her pediatric neurologist, Dr. Elizabeth Doll, recommended acupuncture. Although she was initially skeptical, she gave it a chance. Acupuncture transformed Jordan's life. She can now attend school most days without fear that the lights will trigger a migraine and can play volleyball and lacrosse at her best.
Acupuncture therapy in South Asian countries
Acupuncture therapy is increasingly available across South Asian countries. The practice is growing through a mix of government-supported initiatives, private clinics, and integration with traditional medicine systems like Ayurveda. Across these countries, acupuncture is primarily used to treat:
- Pain Management: Chronic back pain, neck pain, arthritis, sciatica
- Neurological Conditions: Paralysis, facial palsy (Bell's palsy), migraine
- General Wellness: Stress, fatigue, weight management, cosmetic concerns
The Future of TCM in Modern Medical Treatment
The future of TCM is not about replacing Western medicine, but about integration. The global strategy is shifting from asking does it work? to "how can we best integrate it into a modern healthcare system?"
A New Global Strategy: Integrative Medicine
The WHO’s new strategy for 2025-2034 formally champions Integrative Medicine. It is defined as an interdisciplinary and evidence-based approach to health and well-being that integrates biomedical and traditional sciences. The goal is to create a unified system where TCM and Western medicine complement each other.
Overcoming the Evidence Gap
The main challenge is the epistemological gap—the difference between TCM's holistic, personalised approach and the one-size-fits-all chemical drug model of clinical trials.
- New Research Models: Experts are calling for a shift away from sham-controlled trials. The priority is now pragmatic trials that compare acupuncture to other active, recommended treatments (e.g., physical therapy) in real-world settings, with long follow-up periods to measure lasting effects.
- Technological Integration: Technology like AI, big data, and advanced imaging (fMRI) is being used to translate TCM principles into a language modern science understands. For example, AI is being developed to objectively analyse the pulse, a key TCM diagnostic technique.
Global Standardisation and Regulation
For TCM to be responsibly adopted, robust regulatory systems are required. The key areas for future international cooperation are:
- Regulation and Licensing: Standardising training and certification for practitioners.
- Quality Control: Ensuring the safety, purity, and efficacy of herbal products.
- Evidence Methodology: Agreeing on an internationally accepted model for evaluating scientific evidence that respects TCM's unique nature.
Conclusion
TCM is not being dismissed or fully embraced by modern medicine. Instead, it is undergoing a rigorous process of scientific scrutiny. The result is a future where acupuncture and other TCM therapies are likely to become increasingly integrated into standard medical care, particularly for pain management and stress-related conditions, guided by a new, hybrid model of evidence-based integrative medicine.
