Onion juice gives chills through my body. When i was a kid and a bit ill, my mother made me onion juice as medicine. The worst thing i ever drank or ate. Me and my siblings usually tried to hide our cold just because of onion juice. Judt boiled onions and you were supposed to drink it because my mom read it in some magazine where it said it is good for curing a cold.
You poor one. My mother also gave me "onion juice" when I got a cold, but there was one big difference: The onions were cooked with tons of rocked candy. I have to admit that it was my favorite medicine.
Maybe you should try that recipe to cure your onion juice trauma ;)
I used to get a lot of sinus infections, to remedy this, I drank for an extended period of my life cooled "onion juice" (onion + water + honey, cooked for ~1h). My whole family was disgusted by it, but I somehow enjoyed it.
