The Gut-Brain Connection in Traditional Chinese Medicine

The Gut-Brain Connection in Traditional Chinese Medicine

The gut-brain axis is at the center of scientific research today, but Traditional Chinese Medicine (TCM) has described this link for millennia. Through the balance of the "Spleen-Pancreas and Stomach" system, acupuncture acts directly on mental health and the gut microbiota.

The Spleen-Pancreas and Stomach organs in TCM should not be confused with the corresponding organs in Western medicine; they are translations of Chinese ideograms indicating the digestive system's function of digesting and absorbing nutrients. Therefore, they differ in activity and function from the physical spleen and stomach organs of Western medicine.

What is the gut-brain axis in TCM?

In TCM, the gut-brain axis, under the control of the Spleen-Pancreas and Stomach, has the task of transforming food into energy (Qi) and blood—the two elements that control organic functionality (Qi) and the body's nourishment (blood). If digestion is slow, the mind becomes confused. A bidirectional link exists: stress damages digestion, and an inflamed gut generates anxiety and rumination.

The central role of the Spleen and Stomach in TCM For TCM, the Spleen is not just a physical organ, but an organic system with both physical and psychic functions which, in conditions of imbalance, can present:

• Spleen in balance: Produces clear thoughts and a strong memory.
• Spleen in deficit: Generates obsessive thoughts and mental fatigue.
• The Stomach: It is the "sea of nourishment" and influences sleep quality and inner calm.

How acupuncture acts on the Microbiota and the Vagus Nerve

Acupuncture does not only treat pain. Modern research shows that stimulating specific points sends signals to the brain through the vagus nerve, the main "communication cable" between the belly and the head.

Regulation of stress and digestion

When we are stressed, the body activates the sympathetic system (fight or flight), blocking digestion. Acupuncture activates the parasympathetic system, which allows the body to:

• Reduce inflammatory cytokines in the gut.
• Improve microbiota biodiversity, favoring the growth of beneficial bacteria.
• Regulate serotonin, 95% of which is produced in intestinal tissues.

FAQ: Frequently Asked Questions on Acupuncture and the Gut

• Can acupuncture help reduce intestinal anxiety? Yes. Acupuncture reduces cortisol levels and relaxes the smooth muscles of the gut, breaking the vicious cycle between emotional tension and colitis.
• How long does it take to see results on the microbiota? Although symptom relief can be immediate, stabilizing the microbiota usually requires a cycle of 6-8 sessions, accompanied by a specific diet.
• What are the most used acupuncture points for the gut-brain axis? The most studied point is ST36 (Zusanli), located on the leg below the knee. Clinical studies confirm that its stimulation increases vagus nerve activity and protects the intestinal barrier.

Scientific Note: A study published in Frontiers in Endocrinology highlights how electro-acupuncture can modulate the gut microbiota similarly to probiotics.

Conclusion: An integrated approach

To position oneself in the wellbeing of the future, it is necessary to combine the precision of TCM with scientific validation. Healing the gut means, to all intents and purposes, healing the mind.
