Area of Science:

Integrative Medicine
Neurology
Evidence-Based Practice

Context:

Complementary therapies are frequently utilized for chronic pain, including migraine management.
Migraine prophylaxis remains a significant clinical challenge, necessitating exploration of diverse treatment modalities.

Purpose:

To review evidence from randomized controlled trials (RCTs) on complementary therapies for migraine prophylaxis.
To assess the efficacy of acupuncture, homeopathy, herbal medicines, and spinal manipulation for migraine prevention.

Summary:

Acupuncture has the most extensive research (15 RCTs), with a majority suggesting effectiveness despite study heterogeneity.
Evidence for herbal medicines, specifically Tanacetum parthenium (feverfew), is promising, supported by five trials.
Results for individualized homeopathy and spinal manipulation are conflicting, with limited high-quality evidence.

Impact:

Highlights promising complementary therapies for migraine prophylaxis, guiding clinical practice and patient choice.
Identifies research gaps and the need for further high-quality randomized controlled trials to confirm efficacy and standardize treatments.
