Acupuncture 针刺

What it is

Hair-fine sterile needles, inserted at chosen points and left for perhaps twenty minutes — sometimes twirled, warmed with moxa, or given a gentle electrical pulse. The tradition frames the points along the meridians as places where the flow of qi can be adjusted^[1]; the sensation patients learn to recognize — a dull, spreading heaviness called de qi, "obtaining the qi" — is considered part of the treatment working. A session is unhurried and, most first-timers are surprised to learn, largely painless.

What the evidence says

Acupuncture is the tradition's best-studied export, and the mainstream verdict has quietly firmed up: reviews find it more effective than no treatment for chronic back and neck pain, with effects comparable to NSAIDs in some studies; similar findings hold for knee osteoarthritis, moderate-quality evidence supports it for reducing migraine frequency, and post-surgical patients have shown reduced pain and lower opioid use^[2]. Debates continue about mechanisms and about how much sham-needling shares the effect — but "helps chronic pain" is now a defensible, evidence-backed sentence, which is rare currency in this field.

Safety — mostly reassuring

With sterile single-use needles (an FDA device requirement) in trained hands, complications are few^[2]. The serious injuries on record — infections, punctured organs — come from improper practice, which is the real argument for seeing someone properly licensed rather than broadly gifted^[2]. Tell your practitioner about blood thinners and pacemakers.

Where it sits in the grove

Licensing is exactly what the Fourth Hall is being built for: verified, licensed acupuncturists, state by state. Until it opens, your state's acupuncture board keeps the public roll.
