Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study investigates the optimal dose of fermented deglycyrrhizinated licorice (FDGL) that maximizes both safety and efficacy in managing diabetic neuropathy complications in adults. The study is a single-center, double-blind, parallel, placebo-controlled randomized clinical trial where patients with diabetic neuropathy are randomized to receive placebo, 400 mg, 800 mg, 1000 mg, or 1200 mg daily doses of FDGL for three months. The primary objective is to determine the percentage improvement of diabetic neuropathy presentations and pain scores at three months relative to baseline.
