This notion is reasonably supported by the previous reports indicating that (1) A. dahurica polysaccharide accelerates rat skin cell proliferation [40], (2) emodin can aid in maintaining normal mammary gland histopathology and attenuating myeloperoxidase activity (the increase in which reflects the mammary gland injury) in LPS-induced mastitis mice [41], and (3) emodin accelerates cutaneous excisional wound healing and improves tissue reorganization in a rat model [42]. Here, MPO is linked to mastitis.
