Acupuncture: An Evidence Review and Practical Guide for Korea Residents

Acupuncture involves inserting fine stainless steel needles at specific anatomical points to stimulate nerve fibres, release endorphins, and modulate pain signals — based on the traditional East Asian medicine concept of qi (vital energy) flowing along meridians. While the traditional explanatory framework differs from Western medicine, neurophysiological research has identified measurable effects: acupuncture stimulates A-delta and C sensory fibres, triggers endorphin release, and activates brain areas involved in pain modulation and emotion.

The strongest evidence for acupuncture exists in chronic musculoskeletal pain (lower back pain, neck pain, knee osteoarthritis, shoulder pain), chronic headache and migraine prevention, chemotherapy-induced nausea (alongside conventional antiemetics), and labour pain. Multiple systematic reviews including those from the Cochrane Collaboration support acupuncture for these indications with effect sizes greater than sham (placebo needle) acupuncture, suggesting genuine physiological effects beyond placebo.

In Korea, acupuncture is practised almost exclusively by licensed Korean Medicine doctors (한의사, hanuisa) — a distinct, nationally regulated medical profession requiring a 6-year university degree and a national licensing examination administered under the Ministry of Health and Welfare. This is a notable difference from many Western countries, where acupuncture is often practised by physiotherapists or other allied practitioners with shorter training. Korean Medicine clinics (한의원, hanuiwon) operate in nearly every neighbourhood nationwide — most patients attend seeking pain management, stress reduction, fertility support, and migraine prevention. Acupuncture needles are single-use, sterile, and disposable in all licensed Korean Medicine facilities.
