    Introduction: The rhizomes of Zingiber roseum plant have been used in traditional medicine to treat several ailments. Regardless of worth, no research has accounted its toxicity potential. So, the study was designed to determine safety and toxicity potential of Zingiber roseum rhizomes (ZRR) in acute oral toxicity model in swiss albino mice. Methods: Acute oral toxicity was assessed as per the guidelines of �The Brazilian Agency of National Health Surveillance'. In an acute toxicity investigation, 300 mg/kg, 600 mg/kg, and 1200 mg/kg of ZRR extract was orally administered to mice. Thereafter, the animals were monitored for 14 days. To analyze any potential toxicity, general behavior of animals, clinical symptoms of poisoning, body weight, biochemical and hematological marker, and liver histology was carried out. Results: Oral dosing of 300, 600, and 1200 mg/kg of crude extract did not produce mortality or any adverse effect in the laboratory animals. The control and treatment groups of mice exhibited similar behavioral characteristics, neurological signs and total body weight during the treatment period of 14 days. The markers of liver damage i.e., ALT and AST, total serum protein, and albumin did not show any significant change between extract-treated and control mice. The extracts also significantly suppressed ALP activity as compared to control. Kidney function was assessed in mice by measuring creatinine and urea level and no change was observed in level of creatinine and urea in experimental animals. Moreover, no alterations were observed in hematological markers and lipid profile (triglyceride and total cholesterol level). In addition, the liver showed normal architecture and no significant adverse consequences on histopathology analysis. Discussion & conclusion: These outcomes propose that LD50 of rhizomes of Z. roseum is higher than 1200 mg/kg b.w. and might be possibly safe for consumption. � 2023 The Author(s)

    Formulation and evaluation of SGLT2 inhibitory effect of a polyherbal mixture inspired from Ayurvedic system of medicine
    (National Taiwan University, 2022-03-22T00:00:00) Kumar, Ankit; Negi, Anoop Singh; Chauhan, Ashutosh; Semwal, Ravindra; Kumar, Rajnish; Semwal, Ruchi Badoni; Singh, Randhir; Joshi, Tushar; Chandra, Subhash; Joshi, Sunil Kumar; Semwal, Deepak Kumar
    Background and aim: The ingredients viz., Artemisia roxburghiana, Cissampelos pareira, Stephania glabra, Drimia indica, Roylea cinerea, Tinospora sinensis and Curcuma longa of the present formulation are used to treat diabetes in the Indian traditional medical system. Adopting the concept of multiple herbal mixtures for better therapeutic effects from the ancient Ayurvedic text Sarangdhar Samhita, the present study aimed to develop a polyherbal formulation (PHF) of seven herbs and to evaluate its sodium-glucose cotransporter protein-2 (SGLT2) inhibitory effect on type 2 diabetic rats. Experimental procedure: Streptozotocin (STZ) (60 mg/kg) and nicotinamide (NAM) (120 mg/kg) were intraperitoneally administered to induce type 2 diabetes in Wistar rats. The animals were divided into 5 groups viz. normal control, diabetic control, positive control (dapagliflozin at 0.1 mg/kg) and two test groups (PHF at 250 and 500 mg/kg). Various parameters including blood glucose, serum glutamic pyruvic transaminase (SGPT), serum glutamic-oxaloacetic transaminase (SGOT), bilirubin, triglycerides and creatinine were measured. Results and conclusion: The treatment with PHF (250 and 500 mg/kg) showed a significant (p < 0.05) decrease in blood glucose levels by 56.37% and 58.17%, respectively. The levels of SGOT, SGPT and bilirubin were significantly reduced in PHF-fed diabetic rats. Histopathological examination revealed no major changes in the treated groups as compared to the normal control. The molecular docking study showed strong binding of ?-sitosterol, insulanoline, warifteine, dehydrocorydalmine, taraxerol acetate, lupeol, corydalmine and luteolin to SGLT2 protein. The present study concludes that PHF has promising antidiabetic activity via inhibiting SGLT2 protein without showing any adverse effects. � 2022 Center for Food and Biomolecules, National Taiwan University
