Study on the effect of medicinal leech therapy (Hirudo medicinalis) on full-thickness excisional wound healing in the animal model.

The possible impacts of alternative and conventional medicines on wound healing are now of growing interest. This study aimed to evaluate and elucidate the wound healing activity of medicinal leech therapy in wound excision of the rat model. After a round, full-thickness excision was made in the dorsal region of the body, the animals (n = 30) were randomly divided into three equal groups: I) the treatment group (MLT), where the wounds received leech treatment; II) the positive control group (PC), where the wounds received 1% sodium phenytoin treatment; and III) the negative control group (NC), where the wounds did not receive any treatment.
