Study focus
This study evaluated the safety and efficacy of Centella asiatica as a dietary supplement for glycemic control in individuals with type 2 diabetes, finding a significant reduction in HbA1c levels.
These findings suggest that Centella asiatica could be a beneficial dietary supplement for managing glycemic control in type 2 diabetes, potentially offering an additional strategy for patients seeking to improve their blood sugar levels and overall health.
The study's sample size may limit the generalizability of the findings. The duration of the intervention may not reflect long-term effects. The study did not measure other potential confounding factors.

Centella asiatica significantly reduced HbA1c levels by -0.14% (p = 0.006).
No significant differences were found in fasting plasma glucose between groups.
LDL cholesterol levels showed no significant change (p = 0.536).
Centella asiatica was well tolerated with mild gastrointestinal symptoms reported in 14.7% of participants.
