Some of you have such a way with words! I have been laughing my head off at the images conjured by these posts...
HH My Mum always used vinegar on our heads 'for the shine' but we also never had head lice, so it may have deterred them somehow.
When we had a stubborn fever, she also used to give us what she called 'vinegar baths', which was a sponge bath with vinegar and tepid water.
If she had added salt, we could have been mistaken for a bag of chips (crisps).
Yeah, I know, obvious...oh well....
The poultice thing....mum had her life saved as a one year old with pneumonia when her granny used some sort of poultice on her back all night long, after the doctor had written her off. He had said "She'll no see the morning.' To which my Mum's Granny replied "Not if I have anything to do with it." or something more Glaswegian which meant the same thing.
Lucky she was around or I probably wouldn't be here!
