Ginger has a lot of medicinal properties. I usually prepare this chaaru when suffering from severe cold. The addition of honey compensates the hot taste of ginger. While drinking this, you will get pricking sensations in your mouth. It is very fierce. But after a while you will feel very much better.
When my daughter suffers from cold, it is very hard to make her drink this. So I still make her drink from sangu ( a small shell like cup used to give medicines for kids)
