Yep, I remember the onion poultice well, for colds; you smelled for two weeks like rotten onions.Vicks salve was popular then; they would rub your chest, then stuff some up your nose for good measure.Then there was the "sheepie tea", but I will not get into that ! Olive oil & sweet oil are one and the same; but we didnt have any olive oil back then. Shelby
