Not really restricted to DIY but...

When I was a kid we used to buy a tub of gloop called Lion Ointment[1]
for dressing wounds. It was particularly good for dealing with dirty
wounds, or ones with fragments in like splinters, or gravel acquired
while aquaplaning off one's bike across a new road surface etc. Slap
some on, dress it, and a day or so later it would have drawn anything
that should not have been in there out and into the dressing. It was
very effective on septic wounds as well. Alas they no longer seem to
make it, so what do people use these days as a drawing agent on a wound?

A plaster and a kiss from mummy
