This is the recipe from my friend Carol B. Her doctor gave it to her and it is amazing. Try to use a couple of small (1x1 inch) chunks of FRESH ginger if you can. I keep some in the crisper drawer all winter. In a pinch you could try dry ginger in a spice can but I don't think it would work near as well.
It tastes GOOD when you have a cold. Buy some fresh ginger and be ready to make it next time someone is getting that scratchy throat or already has congestion
In a medium pot
2 pieces of fresh ginger, crushed
3 large or five small GREEN onions. white part and roots only( I look for some with long roots).
3 cups water.Bring to a boil, then simmer for 10 minutes.
Add 2 to 3 tablesoons of brown sugar.
Drink warm before bedtime ( or anytime you need a boost) Lin
