Onions for cough and congestion: My first child was colicky and had several colds with congestion. The doctors gave him antibiotics that did not seem to help. I felt like the cold went away on its own. My grandmother told me about the onions. My second and third children never had to take antibiotics. I would take a onion or part of onion about the size of a golf ball and grate up in a bowl.Sprinkle with 1 teaspoon of sugar. Cover and put in the fridge for 45 minutes. The sugar draws the syrup out of the onion. I would then take a dropper full and give to the child. It does not taste bad (try it yourself). It clears their chests and helps them sleep. I never had a problem with using it. Now when I feel like I am getting a cold I always eat more raw onions.
