Formalin has long been the standard fixative for clinical routines worldwide. After the Formaldehyde Standard became law in the US in 1987, as a result of increasing concerns about the potential carcinogenicity of formaldehyde, attempts have been made to find safer alternatives. Alcoholic formalin is a useful fixative, because in addition to fixation, dehydration also is begun.
For centuries, honey has been known to be an antibacterial agent with the potential to preserve compounds without harmful effects on its users. We compared the effects of honey fixation with other routine fixatives using conventional histochemical and immunohistochemical staining methods.
Our results demonstrated that tissues fixed in either honey or alcoholic formalin and 10% neutral buffered formalin (NBF) have similar histomorphology. Honey fixation showed minor histomorphological differences among the various tissues; however, it did not influence affect correct diagnostic conclusions.
Our results suggested that honey can be used as a safe alternative to formalin in histopathology.
