“…Confirmatory safety was conducted in this study using human skin fibroblasts cells. These epidermal cell responsible for skin firmness, is ease to be destroyed by means of oxidative stress in particular lipid peroxidation resulting skin wrinkles that are the sign of aging 18,41 . The extract was concluded as safe according to the viability of the fibroblast cells of more than 100 at various concentrations Fig.…”

“…The untreated cells were used as control. Cell viability was calculated, that of more than 75 comparing with the control 100 cell viability was interpreted as non cytotoxic 18 .…”
