Herbal acupuncture for type 2 diabetes: A meta-analysis.

Area of Science:

• Integrative and Complementary Medicine
• Endocrinology and Metabolism

Background:

• Type 2 diabetes mellitus (T2DM) is a global health concern requiring effective management strategies.
• Herbal acupuncture (HA), an adjunctive therapy, involves injecting natural substances into acupuncture points.

Purpose of the Study:

• To systematically review and meta-analyze the evidence on the effectiveness of HA for T2DM management.

Main Methods:

• A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted.
• Searched three databases for RCTs evaluating HA in T2DM patients, focusing on Fasting Blood Glucose (FBG), Postprandial (PP2hr) glucose, and Glycated Hemoglobin (HbA1c).

Main Results:

• Meta-analysis of seven RCTs (n=598) showed HA significantly reduced FBG, PP2hr glucose, and HbA1c (P<0.0001, P=0.0005, P=0.004).
• No significant effects were observed on lipid profiles (total cholesterol, HDL, LDL, triglycerides).
• High heterogeneity was noted in most analyses, except for HDL and LDL cholesterol.

Conclusions:

• HA may offer benefits for glycemic control (FBG, PP2hr glucose, HbA1c) in T2DM patients.
• Limitations in current studies necessitate further rigorous RCTs to confirm efficacy and overcome methodological weaknesses.
