Try it for a cold but you can't take medicine. It takes less than 10 minutes before and after. The taste is much better than expected (as long as you usually eat vegetables and eat green onions, you should be acceptable).
Cut the scallion and cut into pieces, wash and add water.
Boil the fire and cook for about 3 minutes on a low heat until it has a hint of onion. Turn off the fire.
Pour into the bowl and cool.
Drink water and leave green onions.
Drink a bowl before going to bed, but the next day, although he did not recover, but at least get up a lot better than the previous day, you can smile.
