Mum’s really do have the magic touch! There’s a scientific reason why we should kiss those boo-boos better.

Researchers found saliva has properties that can boost recovery, which is why cuts in the mouth heal quicker, reports Daily Mail.

Professor Vicente Torres, of the University of Chile, said: ‘These findings open new alternatives to better understand the biology underlying the differences between oral and skin wound healing. We believe the study could help the design of better approaches to improve wound healing in tissues other than the mouth.’

Prof Torres and colleagues made the breakthrough by delving into the mystifying fact mouth wounds mend better and quicker.

Until now, it was understood saliva played a part in the wound healing process, although the extent of its role was unknown.

The study examined the effects of histatin-1 on new blood vessels, a process known medically as angiogenesis.

It showed the molecule promoted angiogenesis, as well as improving the contact and migration of cells.

Prof Torres’ team carried out experiments on chicken embryos and human skin and blood vessel cells.

Using these three models, histatin-1 and saliva samples obtained from healthy donors were found to increase blood vessel formation.

The researchers have already begun using these molecules to generate materials and implants to aid in wound healing.

Prof Torres said: “Saliva is a key factor that contributes to the high efficiency of wound healing in the inside of the mouth.

“This is not only attributed to physical cues but also to the presence of specific peptides in the saliva, such as histatins.

“Histatin-1 is an antimicrobial peptide, highly enriched in human saliva, which has been previously reported to promote the migration of oral skin cells in lab animals.

“However, the participation of histatin-1 in other crucial events required for wound healing, such as angiogenesis, is unknown.

“Specifically, histatin-1 promoted skin cell contact and spreading as well as migration in the wound closure tests.

“Finally, we showed that salivary histatin-1 is required for the promigratory effects of saliva on skin cells.

The research, published in The Federation of American Societies for Experimental Biology Journal, revealed the protein histatin-1 found in saliva aids wound healing by boosting the formation of blood vessels. While it was understood saliva played a role in healing, the extent of its role was unknown.

Sometimes a kiss from mum (or dad!) is all that is needed to help sooth a child, now we know it is more than just comforting though!

  • Glad to hear it really does some magic, cheers.


  • oh wow i thought that it would be the opposite actually! wow mind blown! i still wouldn’t want to kiss an ouchie though but they sure can have a sympathy kiss lol


  • That may make things worse if the Mum has some type of infection which could transmitted via her mouth.


  • Isn’t that interesting! Well, us mums are pretty clever!


  • I had never heard the term “kiss a boo-boo” before. Whatever works tho! :)


  • I may kiss them but never their graze or actual boo boo. Glad it works though.


  • An old wives tale that turns out to be true. Thanks for the post.


  • Very interesting – but doesn’t this mean that we should be rubbing spit on their ‘boo-boo’s’? ;)


  • Good to know I really did have the magic touch. Unfortunately, it no longer works on my 16 year old!!


  • I knew there was a reason I’m always drawn to kisses my daughter’s ouchies. Glad to know it really helps ????


  • An intersesting study,who knew!


  • Cool.


  • Good to know ! better make good use of this knowledge ;)


  • That’s really interesting. You don’t need to tell me twice – any excuse to kiss my son <3


  • Wow! How interesting is that! Keep kissing mommas!
