Yes! My mom used to do it to us growing up. Always helped

@lovelyasiamarie, my son hated it and he’s back to his real self!! I’m so glad I did it! I really does work lol but I’ll definitely be placing a slice or two under his bed tonight?

Onions absorb all the toxins and are very good at treating colds. You could leave a sliced onion under there bed or next to it and it will absorb the sickness lol just because some kids might not like the feeling.
