For centuries, Hypericum perforatum has been used in folk medicine to treat wounds. In the present study, the wound healing activities of extracts of H. perforatum ssp. perforatum (HPP) and H. perforatum ssp. veronense (HPV) were evaluated by comparing with a titrated extract of Centella asiatica (TECA) on NIH3T3 fibroblasts. The cells were incubated with the extracts. Using microscopical methods by staining cells, mitotic ability, morphological changes and collagen production in the fibroblasts were evaluated as parameters to approach possible wound repair mechanism(s). The wound healing activity caused an increase in the percentage of polygonal fibroblasts and in collagen granule numbers in fibroblasts of HPP and HPV. At 1 µg/mL, HPP caused a greater increase in mitotic cell numbers than HPV. The most increases in polygonal cell numbers were observed with HPV at 1 and 10 µg/mL. The number of collagen granules was increased with 1 µg/mL HPV being higher than HPP. As an indication of cytotoxic effects, round cells in response to HPV and HPP extracts, were found to be increased in concentrations higher than 10-50 µg/mL. The results indicated that the two subspecies of H. perforatum have different wound healing profiles as a result of the fibroblast migration and stimulation of collagen synthesis.
