Hot mustard rub/poultice on your chest for colds! My mom used to do this to us, and I just remember having a hot red chest.
Milk- Toast when you had the flu. Cinnamon Sugar toast cut & put into a hot bowl of milk to calm tummy.
Raw Buckwheat Honey for chest tightness... I give this to my kids, taste like molasses and reduces swelling in bronchial tubes. A Pediatrician told us this works better than over the counter meds, and it's true.
Whisky or an asprin on a toothache for relief. I usually just have to drink the whisky
Chewing on spearmint leaf for tummy aches, my dad always had it growing in the garden.
Scotch tape over mosquito bites, help it stop spreading and not itch so much. Toothpaste too.
Bag Balm, we used it on everything, kind of like Windex in the My Big Fat Greek Wedding movie.
I know I have a ton more, my mom would come up with the craziest stuff. Sorry if any are repeats.
What a fun thread.
