Maybe just an old wives tale
I have never tried this but thought it worth passing on to those of you who suffer from toe nail fungus. First of all cut down your sugar intake as this helps the fungus grow, bathe in salt water regularly and rub on Vick’s Vapour rub!!! I don’t sell it so it’s not a plug but came from a good source that it is really effective. Simple, cheap and worth a try? Alternatively there is Tea Tree Oil. That I do sell and know that it is a very effective natural antisceptic. Usually you will need to dilute it, but it woud be OK undiluted on an adults toes.
