Stick onions in your nose.

What about nasal congestion after a cold? When sleeping, you can put a fresh onion strip in each nostril and take it out after 3 hours, usually once. If not, you can plug it in the next day. It is worth reminding: first of all, the onion strips should be thicker and thinner. First, the drug intensity is small; Second, it is easy to inhale deep into the nasal cavity and not easy to take out; Secondly, if the patient's nasal cavity is allergic to fresh onions, a thin layer of cotton wool can be wrapped around the onion strips.

If not, go to the hospital.
