Der Pharmacia Sinica, 2011, 2(1); 118-128 states that Aqueous extract & methanolic extracts of Keukand are highly effective in bringing down the blood glucose levels. Its root extract possesses anti-hyperglycemic, anti-hyperlipidemic & antioxidative effects, which are helpful in the management of diabetes and its complications.

IJPSR, 2011; VOL. 2(3): 494-500 observed that oral administration of ethanolic extract of Karanja shows significant anti-hyperglycemic effect and enhancement in the antioxidant defense system.

Phenolic compounds present in Babool extracts significantly reduced blood glucose levels, cholesterol, and triglycerides. Histological studies of the beta cells show its action on the pancreas according to Int. Res. J. Medical Sci. vol.2(5), 20-24, May 2014.

Karela extracts and isolated components exert their hypoglycemic effects via different physiological and biochemical processes. Oral administration of Karela could lead to the secretion of insulin from endocrine pancreatic beta cells. Charantin, polypeptide-p, and vicine are major compounds isolated from M. charantia which show potential anti-diabetic properties, states Asian Pac J Trop Dis 2013 ; 3(2): 93-102.

The anti-diabetic activity of the plant extracts of Khadira was shown via the reduction of enzymatic activities of alpha-glucosidase, alpha-amylase, and aldose-reductase. Administration of ethanolic extracts of Khedira shows improvement in glucose tolerance according to Hindawi Journal of Chemistry; vol.2021, article ID 2575598.

The herb possesses anti-diabetic effects and sugar inactivation properties. The presence of triterpene saponins known as gymnemic acid, gymnemasaponins, and german account for its hypoglycemic effects according to Biomed Research International vol. 2014; article ID 830285.

Ethanolic extracts of roots of R. cordifolia are reported to be hypoglycemic. The beneficial effect of treatment might be due to different types of active principles each with a single or diverse range of biological activities according to Oriental Pharmacy and Experimental Medicine 2009, 9(1), 1-13.

Methi seeds have been shown to have hypoglycemic effects on type 1 & type 2 diabetes mellitus patients. Ethanolic extracts of methi seed powder decrease blood glucose, serum cholesterol, and SGOT & SGPT levels. Raw and germinated seeds significantly reduce postprandial glucose levels according to IJASR; vol.5; issue 05; 2019.

Long-term treatment with Shilajit increases the number of beta cells of the pancreas which may result in better sensitivity of pancreatic beta cells with the prompt secretion of a large quantity of insulin in response to hyperglycemia according to Indian J Pharmacol; Dec.2004, vol.36, issue 6.

P. Nigrum shows anti-diabetic activity in addition to the anti-oxidant activity which can help overcome the stress created by the hyperglycemic condition of the cells according to IOSR-JPBS; vol. 13; issue 2 ver. II MAR.-APR. 2018, 53-56.

Aqueous, ethanol and hexane bark extracts of P. Santalinus proved to be anti-hyperglycemic. The hypoglycemic effect was attributed due to the phytoconstituents beta-sitosterol, epicatechin, and lupeol which activated remnant beta cells, and improved insulin response at cellular levels (Asian J Pharm Clin Res. , vol. 15, issue 1, 2022)

Oral administration of alcoholic extracts of the leaves of M. umbellatum shows a significant lowering of serum glucose levels according to Journal of Ethnopharmacology, vol.62, issue 3, Oct. 1998.
