type of onion: red onion
you dont have to eat it like this, but you can cook with it too and that would help to clear things up.
this is something that i tried out that seemed to work for me without having to take medicine. i was on the last edge and i had some type of weird flu that had a choke hold on me. i didn’t want to take any pills so figured i could look up natural ways to cure my dilemma and this is what work best for me although i did not eat the whole onion.
