The aim of this research is to investigate the wound healing process in in vitro by combining the Manihot esculenta aqueous extract and therapeutic ultrasound. Firstly, the optimization seeding densities of HSF cell 1184 in six-well plate, and then followed by the scratch assay experiment. The scratched that made was treated with the remedial treatments (Manihot esculenta aqueous extract only; ascorbic acid+ therapeutic ultrasound; Manihot esculenta aqueous extract+ ascorbic acid; Manihot esculenta aqueous extract+ therapeutic ultrasound and also the combination of these three materials). The rate of wound closure was observed and analysed at a time interval of 0, 2, 4, 6, 8, 10 and 24 h by using image J software. Then, the cells viability were analysed using the MTT assay. The result showed that Manihot esculenta aqueous extract coupled with specific dose therapeutic ultrasound represents a significantly high rate of wound closure at 96.10 % with the cell numbers at 5.44×105 cells/mL when compared to the other combination therapy. The finding of this study revealed that Manihot esculenta aqueous extract 200 μg/mL and the therapeutic ultrasound specific dose (3 MHz, 300 mWatt/cm2, 50% in 5 min) have the potential in accelerating wound healing process of cells in in vitro.
