“After a five-week treatment, bitter melon lyophilized superfine grinding powder (BLSP) had a higher antidiabetic activity with reducing fasting blood glucose levels from 21.40 to 12.54 mmol/L, the serum insulin levels from 40.93 to 30.74 mIU/L, and restoring activities of SOD compared with those in the bitter melon hot air drying powder (BAP) treated group. Furthermore, BLSP protected pancreatic tissues including islet beta cells and reduced the loss of islet cells. Combined with the difference of compositions in BLSP and BAP, it could be concluded that superfine grinding and lyophilization processes were beneficial for presenting the antidiabetic activity, which will provide a reference for direct utilization of bitter melon as a suitable functional food to relieve symptoms of diabetes.” ————————————————— https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4027280/
“With the traditional use supported by modern scientific evidence of the beneficial function of M. charantia, it is one of the most promising plants for diabetes today[11],[61]. Investigation of the traditional uses of M. charantia in India revealed that it is one of the most important plant for lowering blood glucose levels in patients with diabetes[43].”
