Do you have any home remedies you use when you or a family member gets sick?

Right now I have a cold so I'm drinking lots of tea with honey to sooth my throat. Ordering egg drop soup later for my sinuses. That's about all I've got.

My coworkers from Africa have a lot of at home remedies & rarely get sick or go to the doctor. There is some to be said about that.

What have you heard or tried that has worked for common ailments?
