The study evaluated the effects of hydromethanolic extract of M. jalapa and its terpenoid and flavonoid fractions on wound healing in Wistar Albino rats. The flavonoid-treated group showed a significant decrease in antioxidant enzyme levels, while the terpenoid fraction significantly increased growth factor expression. However, the terpenoid fraction delayed regeneration and remodeling stages, leading to a thicker ulcus layer and lack of hair follicle-like blood capillaries, potentially resulting in hypertrophic scar formation. The study concluded that the terpenoid fraction might prolong the proliferation phase, increasing the risk of hypertrophic wounds.
