Sick

My daughter has a cold, it’s her first one. I’ve talked her temperature also everyday and no fever. She’s extremely hot though. I’ve been giving her Advil every night before bed and sucking her boogers out. She’s been drinking lots of water since she doesn’t want her bottle. Is there any home remedies I can do to help her get better faster? I saw also saw this thing where if you add a little bit of salt to an orange and then squeeze it that’s supposed to help but I don’t know, has anyone done that before?
