Instinctively, animals will lick their injured limbs, such as dogs. According to research conducted by Benjamin L. Hart and Karen L. Powell, dog saliva contains an antiseptic that can be used to kill bacteria. E. coli and Streptococcus. Apparently, this behavior is not only done by dogs, humans instinctively lick the wound so that it heals quickly. But is human saliva as "miraculous" as dog saliva?
Histatin, a content that is in human saliva
Although human saliva has no content epidermal growth factor (EGF) and nerve growth factor (NGF) is high as that of rodents (both of these ingredients are believed to be able to make wounds heal faster), human saliva has been shown to contain histatin. Histatin itself not only functions as an antifungal agent, but also has the ability to accelerate wound healing.
This fact is supported by research conducted by Jia J., Sun Y., Yang H., et al which was published in the PUBMED journal in 2012. This research was conducted on adult rabbits, which made wounds of 2.5 x 2.5 cm on their backs.
This study applies 3 different conditions to see the duration and process of wound closure that occurs. The three conditions are the administration of different substances to see their effectiveness in wound healing. The rabbits were divided into three groups according to the substance that will be applied to the wound on their back. One group was given salt water, one group was given yunnan baiyao powder (a powder that has been widely used to heal wounds), and one group was given saliva.
The result, in the group given saliva and Yunnan Baiyao, wounds heal faster than those given salt water. In the saliva-treated wounds, the healing rates on days 5, 8, and 11 in the wound healing process were better than the other groups. In addition, in the group that was given saliva, the wound that healed was much cleaner, with evidence of no swelling of the cells and the wound was closed again with new skin after 15 days, this was much better than the other groups.
In addition to making wounds heal faster, there is a report presented by a group of researchers from The Netherlands. There is hope that this histatin content can clean wounds in people with diabetes and various other wounds that are difficult to heal. In addition, the ingredients present in saliva are easily mass-produced.
