What the clinical evidence supports — strength and source, plainly stated. From the BMA efficacy & safety review and guideline summaries.
De Qi — the arrival of Qi
Dull ache, heaviness, distension, tingling, warmth, or a radiating feeling around the needle — the arrival of Qi.
De qi is associated with better outcomes; it is both a clinical sign and the patient's felt experience. Twirling, lifting-thrusting, and patient feedback guide it.
Stronger 'de qi' needling is more stimulatory; gentle, brief needling tends toward sedation in modern practice (Campbell).
Chronic pain (general)
Moderate–StrongMeta-analyses show acupuncture is superior to sham and usual care for chronic back, neck, and osteoarthritis pain, with effects persisting beyond treatment.

Chronic low-back pain
ModerateRecommended as a non-pharmacological option; effective for short-term pain and function. Guideline-supported.

Osteoarthritis of the knee
ModerateSignificant improvement in pain and function versus sham and education controls.

Migraine prophylaxis
ModerateReduces frequency; comparable to prophylactic drugs with fewer side effects.
Source: BMA; Cochrane migraine reviews
Tension-type headache
ModerateReduces headache frequency and intensity for prophylaxis.

Post-operative & chemotherapy nausea
StrongP6 (PC6) stimulation is one of the best-supported indications; reduces nausea/vomiting.
Source: BMA; Cochrane P6 reviews
Nausea of pregnancy
ModeratePC6 acupressure/needle reduces nausea; safe when LI4 and contraindicated points avoided.
Source: BMA; obstetric reviews
Neck pain
ModerateShort-term pain relief and function improvement; results vary by technique.
Source: Cochrane neck pain
Shoulder pain (frozen shoulder/rotator cuff)
Limited–ModerateSome benefit for pain and mobility; often combined with manual therapy.
Source: BMA; shoulder trials
Osteoarthritis of hip
LimitedLess evidence than knee OA; small trials show modest pain relief.

Fibromyalgia
LimitedSome improvement in pain and fatigue; evidence heterogeneous.

Insomnia
Limited–ModerateImprovement in sleep quality in several trials; multi-component interventions vary.
Source: Insomnia reviews
Depression/anxiety (adjunct)
LimitedPossible adjunct benefit; not a standalone replacement for psychological care.
Source: BMA; mental-health adjunct reviews
Smoking cessation
InconclusiveEarly studies mixed; auricular protocols show variable results.

Asthma
LimitedSome symptom improvement; evidence insufficient to replace conventional care.
