Effect of Trasina, an Ayurvedic herbal formulation, on pancreatic islet superoxide dismutase activity in hyperglycaemic rats.
Diabetes mellitus was induced in male CF strain rats by streptozotocin (STZ) and hyperglycaemia and superoxide dismutase (SOD) activity of pancreatic islet cells was assessed on days 7, 14, 21 and 28. STZ induced significant hyperglycaemia and a concomitant decrease in islet cell SOD activity. 
Anti-ulcer and antioxidant activity of DHC-1, a herbal formulation
DHC-1, a herbal formulation, was tested for its anti-ulcer and antioxidant activity in rats. Effect of various doses (125, 250, 500, and 1000 mg/kg, p.o.) of DHC-1 was studied on gastric secretion and gastric ulcers in pylorus-ligation and on ethanol-induced gastric mucosal injury in rats. 
Effect of Ciklavit® – a Nigerian Poly-herbal Formulation on the Dissolution Profile of Proguanil Tablets: Potential for Herb-drug Interaction
Aim: Herb-drug interaction is a growing concern due to the increasing consumption of herbal medicines among populations globally. Assessment of potential interaction of herbs with concomitantly administered drugs is thus very necessary to ensure patient safety. The aim of this study was to determine the effect of Ciklavit® on the in vitro release profile of proguanil tablets as indicator of potential in vivo herb-drug interaction.
