Pilot protocol compares Ayurvedic Nimba-Amalakyadi powder versus metformin for type 2 diabetes

Last updated May 26, 2026

Key finding

This article is a pilot trial protocol in adults with newly diagnosed type 2 diabetes that plans to compare Nimba-Amalakyadi powder against metformin over 45 days, with follow-up to day 90, and no final efficacy results are reported yet.

This publication describes a planned pilot randomized open-label trial, not completed efficacy outcomes. It proposes enrolling 36 participants with type 2 diabetes to compare Nimba-Amalakyadi powder versus metformin for 45 days, with day-90 follow-up. The protocol emphasizes feasibility metrics and exploratory glycemic trends, but final comparative results are not available in this article.

evidence suggest

Evidence Suggest

  • Methods section specifies randomized allocation with two groups and 45-day intervention exposure plus day-90 follow-up.
  • The paper explicitly identifies itself as a protocol and states final results are expected after completion phases.
  • Outcome variables are described as planned measurements rather than reported comparative endpoint results.
who this applies

Who this applies to

Adults aged 20-60 years with newly diagnosed type 2 diabetes (<6 months)

keep in mind

Keep in Mind

Interpret this as a protocol, not a completed efficacy trial.

between the lines

Between the Lines

  • This publication is a protocol and does not report final efficacy results.
  • Small planned pilot sample size (n=36) limits inferential strength.
  • Open-label design may introduce performance and expectation biases.
  • Single-center setting may limit generalizability.
