Background: Introduction of metal wire into the tuber of Curcuma longa plant can prove a novel way to use metals to get their therapeutic benefits in Ayurveda. Objective: The aim was to evaluate the effect of C. longa and its fortified varieties on glucose uptake in naïve and insulin resistance 3T3L1 cells. Materials and Methods: Zinc (Zn) and Tin (Sn) metal wire was inserted into the tuber of growing C. longa plant, which was further used as a therapeutic agent and glucose uptake activity was analyzed by measuring uptake of radio-labeled glucose in 3T3-L1 adipocytes, in naïve and insulin resistant state. Results: At the end of 20 min fortified variety of Sn showed dose dependent increase with maximum effect at 50 μg/ml as compared to fortified variety of Zn and control variety that is, C. longa alone. At the end of 24 h both the fortified varieties exhibited lesser glucose uptake when compared to the control variety. In resistant state, glucose uptake was higher in all the groups when compared with dexamethasone treated adipocytes. However, the effect with a fortified variety was lesser than control variety. Conclusion: Insertion of metals (Zn and Sn) into the tubers did not enhance the glucose uptake activity known to be exhibited by C. longa. The present study needs to be explored further in terms of insertion technique, concentration of metals and climatic conditions.
