Pyrangello... My mother used to stick onions in my socks anytime I had a fever when I was a child. Although I was quite repulsed by the feeling of walking around with mushy onions in my socks, it worked everytime
... Funny you mention this story cause I thought she was crazy at the time but mothers always know best so I went along with it... She also used to heat up onion juice and pour it in my ear whenever I had an earache as well, sounds weird but again... worked every time
