Once again – the cut was deep and long and in the palm of his hand – not a good place for a cut to be for an active guy!  But we washed it with hydrogen peroxide (3%) and dusted it with slippery elm powder twice a day for  two days then once a day till it stayed closed and dry.  We packed it with sterile gauze and wrapped it with sticky ace type bandages. 

Hope this gives you the confidence to try it at home!  Use common sense though.
