What is acupuncture? A beginner’s guide to Traditional Chinese Medicine

If you’ve heard of acupuncture but aren’t quite sure what it actually involves, you’re not alone. One of the questions I’m asked most often in clinic is: "How can acupuncture help me?"

Acupuncture has been practised for thousands of years, yet for many people it still feels a little mysterious. This guide answers some of the most common questions I hear and explains what Traditional Chinese Medicine (TCM) acupuncture is, how it works and its main theories.

What is Traditional Chinese Medicine (TCM) acupuncture?

Traditional Chinese Medicine (TCM) is a system of healthcare that has developed over thousands of years and is used by millions worldwide. Acupuncture is one of its best-known therapies, alongside herbal medicine, cupping, moxibustion, Tui Na massage and dietary therapy.

Acupuncture is based on a thorough and subtle diagnosis of someone’s health. One of the things I love most about Chinese Medicine is that no two people are treated exactly the same. Two patients may arrive with the same diagnosis, yet their overall health, constitution and underlying patterns can be very different. As the 17th-century physician Xu Dachun put it “Illnesses may be identical, but the people who have them are different”.

It’s a holistic treatment – treating each individual as a whole. We look at how symptoms and illness connect and at the root causes. We aim to address underlying patterns rather than simply masking symptoms, while recognising that patients may also benefit from conventional medical care where appropriate.

An acupuncture treatment involves inserting very fine, sterile needles into carefully selected acupuncture points around the body. In Chinese Medicine, these points lie along channels known as meridians through which Qi (often translated as vital energy) flows. When Qi becomes disrupted or deficient, symptoms may arise. Acupuncture seeks to restore harmony and promote healthy function.

Becoming a qualified acupuncturist requires years of study and supervised clinical training. In the UK, professional acupuncturists typically complete degree-level education before entering practice.

How does acupuncture work?

This is one of the most researched questions in acupuncture, and the honest answer is that there isn’t a single explanation.

Researching the effects of acupuncture is inherently difficult using traditional randomised controlled trials, which are considered the gold standard. Acupuncture treatments are individualised and creating a truly inactive placebo is near to impossible. Even so-called "sham" acupuncture may produce physiological effects, making research more complex than conventional drug trials.

Despite these challenges, decades of research have identified several plausible biological mechanisms through which acupuncture may influence the body, including:

• Stimulating nerves in the skin and muscles, triggering a range of biological responses and sending signals to the brain and spinal cord.
• Inducing the release of naturally occurring chemicals involved in pain regulation, including endorphins.
• Altering activity in areas of the brain associated with pain perception and emotional processing.
• Influencing blood flow and local tissue responses.
• Supporting regulation of the autonomic nervous system, which helps balance "fight or flight" and "rest and digest" responses.

One particularly intriguing area of research involves the interstitium – a relatively recent anatomical concept describing a vast network of fluid-filled spaces within the body’s connective tissues. Researchers suggest that this interconnected network may play important roles in fluid transport, mechanical support and biological signalling, linking organs, muscles, nerves and blood vessels throughout the body. While this is still an evolving area of science and its full relationship to acupuncture has not been established, it has generated considerable interest because many acupuncture points lie within connective tissue planes associated with the interstitium. In some exploratory studies, dyes injected into acupuncture points have been observed to travel along fascial planes that resemble the pathways of traditional meridians. This offers a fascinating avenue for further research and certainly provides food for thought.

The history of acupuncture

The Nei Jing is the most important and influential text on acupuncture and dates back to around 400 B.C. Long before it, the Chinese had evolved the philosophy of the Dao. It literally translates as the Way or the Path but its concept is harder to grasp. It describes the underlying natural order and rhythms of life.

Rather than viewing health simply as the absence of disease, Chinese Medicine sees wellbeing as a dynamic state of balance between the body, mind and environment. Concepts such as Yin and Yang, the flow of Qi and the changing cycles of nature all stem from this broader philosophy and underpin acupuncture and its aim to encourage the body’s natural ability to regulate and restore balance.

What is Yin and Yang?

Many people recognise the familiar black-and-white Yin Yang symbol, but in Chinese Medicine it represents far more than the obvious opposites. They are complementary and interdependent forces and aspects of life: night and day / hot and cold / stillness and movement / male and female. Neither can exist without the other, and both are constantly changing.

From a TCM perspective, health depends on maintaining a healthy balance between these dynamic forces and adapting to the natural changes of life.

What is dry needling versus acupuncture?

Dry needling and Traditional Chinese Medicine acupuncture both use fine needles, but they are based on different principles and training pathways.

Dry needling is commonly used by physiotherapists to target muscles and trigger points, particularly for musculoskeletal pain. It is a fraction of Chinese Medicine and requires only a short course to gain accreditation compared to a trained acupuncturist who do a minimum of a 3-year degree-level course and 400+ hours of clinical work.

In summary

Acupuncture is a gentle, personalised form of healthcare that has been practised for thousands of years and continues to support millions of people around the world today. At its heart, TCM is about understanding you as an individual, not just your symptoms, and working to restore balance and support your body’s natural ability to heal and regulate itself.

Whether you’re looking for help with stress, sleep, women’s health or simply want to improve your overall wellbeing, acupuncture offers a holistic approach that can also sit alongside any western medical care.

If you’re curious but still have questions, that’s completely normal. Choosing the right practitioner is important, and I’d always encourage you to ask questions and make sure you feel informed and comfortable before beginning treatment. The British Acupuncture Council is a good place to start when finding a practitioner.
