Synergistic potential of Zingiber officinale and Curcuma longa to ameliorate diabetic-dyslipidemia

Abstract

To find the cure of world’s one of the leading morbid and mortal disorders; diabetes mellitus and its most prevalent complication, ‘diabetic-dyslipidemia’, is one of the leading health challenges of 21st century. The use of phytomedicine is a glimmer of hope in this scenario. Studies of current decade have shown that methanolic extracts of Zingiber officinale and Curcuma longa have highly effective therapeutic potentials against the aforesaid disorders, however, which of the extracts has more potential is still unclear. Furthermore, synergistic effect of the extracts has never been studied. Forty-eight Albino adult rats of either sex were randomly divided into eight groups. A-D groups were containing healthy rats while E-H groups were of induced diabetic-dyslipidemic rats. For forty-two days, rats of each group were given either distilled water or Zingiber officinale methanolic extract (ZOME) or Curcuma longa methanolic extract (CLME) or ZOME+CLME therapies at dose rate of 300mg/100 mL dist. H2O/kg body wt/day. FPG and lipid profiles were estimated before and after the trial, and were statistically analyzed by one-way ANOVA along with Posthoc Tukey’s multiple comparison tests. Although, ZOME and CLME significantly (P<0.05) lowered fasting plasma glucose (FPG) levels and controlled lipid profiles in diabetic-dyslipidemic rats; yet, synergistic therapy of both extracts (ZOME+CLME) most significantly (P<0.05) controlled all parameters of diabetic-dyslipidemia (78.00±1.06mg/dL FPG, 62.00±0.58mg/dL TG, 66.50±0.76mg/dL cholesterol, 32.00±0.36mg/dL HDL, 22.43±0.64 mg/dL LDL, and 12.40±0.12mg/dL VLDL). Our findings may be useful to formulate new medicines having multiple potentials to control diabetes mellitus, dyslipidemia, and diabetic-dyslipidemia.
