Shouga Kuzuyu for When you are Sick

The first time I had a shouga kuzuyu was the first time I had a high fever in Japan. A teacher visited me and gave me some food to eat at home. One of which was this shouga kuzuyu.

What this is is a a mixture that you mix with hot water, and you get a thick gingery and sweet drink.

This soup is supposed to be good for when you are sick, although I never understand why or how. I do not actually the taste, but the ginger does warm me up, and it soothes my throat a bit. That is the main reason why I have a couple at home especially during winter.
