In your country/culture, do you have things told by your grandma (or grandpa for that matter)?
For example, in Japan, when you got cold/flu, have Negi (a type of onion somewhat between leek and spring onion) around your neck.
Then yesterday, my friend from the US said, "have a mug of hot water with cayenne pepper. That will clear your nose and head!"
I've never heard of that.
I wonder if other people have that kind of idea. Something we call "grandma's wisdom" in Japan.
Share your idea here! Not only against cold, but anything else will be welcomed.
And, yes, I have cold. I am currently sticking to hot lemon and honey (I went to supermarket to get lemons yesterday!). My friend thinks I should add Cayenne pepper in it...
