Background:
Diabetes mellitus is a disease and endocrine disorder and it's a growing health problem in various countries. The prevalence of diabetes rises worldwide including South Africa 5.4% in 2025 increases as expected. The World Health Organization (WHO) estimated the diabetes mellitus problem in adults 173 million in developing counties. In this research observation of glucose levels indicated the diabetic state in Wistar rats by resulting from Streptozotocin administration and using a Metformin as a standard dose. This study demonstrated the acute oral toxicity and subacute oral toxicity of ethanolic extract of Saraca asoca leaves and Asparagus racemosus roots and showed the antidiabetic activity.
Objective:
To perform acute toxicity studies and sub-acute toxicity of the polyherbal ethanolic extract on the vital organ and isolated organ and record and noticed the visible changes on organs of each group of Wistar rats. Explore the hypoglycaemic action of the polyherbal extract of Saraca asoca and Asparagus racemosus.
Methods:
Wistar rats were divided into required groups for toxicity study first is acute oral toxicity 5,50, 300,2000 mg/kg body weight. Subacute oral toxicity studies were performed by administering a 250, 500, 1000mg/kg body weight. For demonstrating the antidiabetic activity the animals divided into 5 groups 1 normal control given saline group 2 standard dose Metformin compulsory dose groups 3 Streptozotocin-Induced diabetic 150mg/kg body weight body weight, groups 4 ethanolic extracts at a 100mg/kg groups 5 ethanolic extract 200mg/kg. On the last day of all the dosing period examined the Blood glucose levels and body weights of rat and histopathology studied were done by animal sacrifice and cut organs such as tissue pancreas, spleen, heart, lungs, liver, and kidney, placed on the slide and done a microscopic examination. Data selection has been complete by research papers from many databases such as NCBI, Web of science and Science direct and PubMed from year 1989 to 2020 by utilize research. skeywords such as “Antidiabetic”, “Saraca indica”, “Asparagus racemosus”, “ethanolic polyherbal extract”, “oral toxicity study”, “histopathology”, “Streptozotocin.
Results :
The polyherbal ethanolic extract of Saraca asoca and Asparagus racemosus at a dose of 100mg/kg and 200mg/kg was showed better effects against Streptozotocin-Induced diabetic 150mg/kg body weight body weight. All the extracts showed significantly (P <0.05) and it is safe and non-toxic nature by performed a toxicity study acute and subacute oral toxicity and the bodyweight are also improved, no inflammation and erosion are seen on any organs of Wistar rat by demonstrated a histopathology analysis.
Conclusions:
The polyherbal ethanolic extract of Saraca asoca and Asparagus racemosus showed hypoglycaemic activity against STZ-induced diabetes in experimental Wistar rats in Wistar rats. The results are shown beneficial effects of these ethanolic extract it helps in improving the changes in lipid metabolism, and protect the organs of Wistar rat liver, kidney, spleen, pancreas, lungs, heart against due to impairment of blood glucose and also in body weight. All organs were weighted and cut the tissue of organs and stained from eosin dye and changes observed by microscopy photos. no signs of inflammation and erosion.
