I do the cayenne pepper + water trick for sore throats. It really works, for me at least. And apple cider vinegar for canker sores.
And I can't eat noodle soup when I'm sick, cause if I throw up it comes out my nose.
I know you said you could scour the internet for sources for home remedies, but for anyone else that's interested, I go to
Earthclinic Ailments all the time to find remedies for medical issues I get. A lot of them seem to work very well.
