At the heart of traditional Chinese medicine (TCM) lies a fascinating and profound concept: Qi (pronounced “chee”), the vital energy that circulates through the body along pathways known as meridians. According to TCM, blockages in this energy flow lead to the onset of disease, pain, or emotional imbalance. One of the most well-known methods for restoring the flow of Qi is acupuncture.
This ancient practice involves inserting very fine needles at strategic points on the body, aiming to balance energy and stimulate the body’s natural healing capacity.
Scientifically Explained Benefits
Chronic Pain Relief
Acupuncture stimulates the production of endorphins (natural pain relievers) and modulates pain perception at the level of the central nervous system. The needles inserted into the skin activate nerve fibers and influence brain areas associated with pain.
Reduction of Stress and Anxiety
Acupuncture acts on the hypothalamic-pituitary-adrenal (HPA) axis, involved in stress reactions. By regulating this axis, cortisol secretion is reduced, improving overall mental state.
Support for Digestion and Hormonal Balance
In TCM, the stomach and spleen are considered the main sources of energy. By stimulating points along these meridians, acupuncture helps alleviate irritable bowel syndrome, reflux, and hormonal imbalances, such as premenstrual syndrome or thyroid disorders.
Immune System Stimulation
By regulating the function of internal organs and stimulating lymphatic circulation, acupuncture contributes to strengthening immunity. It is often used preventively during seasonal changes.
Medical Statements
Acupuncture offers an effective alternative for patients who do not respond to conventional therapies or do not wish to undergo long-term pharmacological treatments.
Dr. Cristina Popa, specialist in integrative medicine
There is a solid scientific basis for the effects of acupuncture, especially in pain modulation and in regulating the stress response.

Important Studies and Research Explained in Detail
1. Acupuncture for Chronic Pain: Individual Patient Data Meta-analysis
Publication: Archives of Internal Medicine, 2012
This is one of the most comprehensive studies on acupuncture. It analyzed data from 29 randomized clinical trials and over 18,000 patients suffering from chronic pain (back pain, knee pain, osteoarthritis, and migraines). The result? Acupuncture was significantly more effective than placebo treatments and than no treatment at all.
Conclusion: The efficacy of acupuncture is real and exceeds the placebo effect.
2. Effects of Acupuncture on Hypothalamic-Pituitary-Adrenal Axis in Rats Under Stress
Publication: Journal of Endocrinology, 2013
This animal experimental study demonstrated that acupuncture has a regulatory effect on the HPA axis (hypothalamic-pituitary-adrenal), responsible for the stress response. After applying needles to certain points (e.g., Zusanli ST36), stressed subjects showed lower cortisol levels and normalized neuronal activity in the hypothalamus.
Conclusion: The physiological effects of acupuncture are measurable at hormonal and neuronal levels.
3. WHO Report: Acupuncture Review and Analysis of Reports on Controlled Clinical Trials
Publication: World Health Organization (WHO), 2003
This official WHO report analyzes over 200 clinical studies and concludes that acupuncture is effective for at least 28 conditions, including: low back pain, nausea, migraines, dysmenorrhea, and mild hypertension. An additional 63 conditions are mentioned as likely beneficial but require further research.
Conclusion: WHO recognizes acupuncture as a valid therapeutic method for numerous conditions.
4. Acupuncture and the Brain: The Impact of Acupuncture on the Central Nervous System
Publication: Autonomic Neuroscience Journal, 2010
This review article explains how acupuncture activates various brain regions, including the insula, cingulate cortex, and brainstem. It was found, through functional imaging (fMRI), that acupuncture points produce measurable changes in cerebral blood flow and neuronal signals.
Conclusion: Acupuncture has a direct effect on brain activity and can influence processes such as pain, fear, digestion, and hormonal balance.
Contraindications and Precautions
-
Pregnancy: certain points (e.g., LI4, SP6) may stimulate uterine contractions.
-
Hemophilia or anticoagulant treatment: increased risk of bleeding.
-
Immunocompromised individuals: acupuncture should only be performed in sterile conditions.
-
Metal allergies (nickel, stainless steel): gold or special plastic needles are recommended.
-
Unstable mental conditions: may exacerbate anxiety in individuals with severe needle phobias.
The essential recommendation is that acupuncture should only be performed by authorized personnel, with experience in Chinese medicine and medical training.
