An evidence map on traditional medicine across health outcomes.

Researchers created a comprehensive map of systematic reviews examining traditional medicine treatments, including acupuncture, across various health conditions. They analyzed 2,719 systematic reviews published between 2018 and 2022, searching through 17 medical databases to understand what evidence exists for traditional medicine practices.

The study found that acupuncture was the second-most researched traditional medicine approach, with 471 systematic reviews examining its effectiveness. Herbal medicine was studied most frequently with 1,867 reviews. These treatments were most commonly investigated for digestive system disorders, circulatory problems, and genitourinary conditions. Nearly all research focused on adults, with only 128 reviews studying children.

What does this mean for patients? This evidence map reveals that acupuncture has been extensively studied across many health conditions, making it one of the most researched complementary therapies available. However, the researchers noted that the quality of many systematic reviews was considerably low according to standard assessment criteria, meaning the strength of evidence varies widely depending on the specific condition.

For patients considering acupuncture, this study confirms that substantial research exists examining its potential benefits, particularly for digestive, circulatory, and genitourinary issues. The large number of reviews suggests growing scientific interest in understanding how acupuncture works and which conditions it may help. However, patients should understand that research quality varies, and more high-quality studies are still needed for many conditions.

This evidence map helps identify where gaps exist in traditional medicine research and where future studies should focus. If you're considering acupuncture treatment, consult with a qualified, licensed acupuncturist who can discuss the specific evidence for your particular health concern.

This evidence map systematically analyzed 2,719 systematic reviews of traditional medicine modalities published from January 2018 to December 2022 across 17 databases. From 241,509 initial records, researchers mapped interventions by ICD-11 disease classification and health outcomes. Acupuncture represented 471 systematic reviews (second only to herbal medicine at 1,867), primarily investigating diseases of the digestive, circulatory, and genitourinary systems. The study population was predominantly adults (n=2,591) with minimal pediatric research (n=128). Methodological quality assessment using AMSTAR 2 criteria revealed considerably low quality across included systematic reviews, indicating significant heterogeneity in research rigor. Clinical takeaway: While acupuncture demonstrates substantial research volume across multiple health conditions, the low methodological quality of existing systematic reviews suggests practitioners should critically evaluate individual study quality when making evidence-based treatment decisions. This map identifies critical research gaps and priority areas for future high-quality systematic reviews in traditional medicine modalities.
