manman,
You can use the ginger skin to make ginger water so you don't need to buy extra ginger lor. Last time, my mom peeled all the skin of the ginger and dried it under the sunlight. When I needed to make ginger water to wash my hair and take a bath, I boiled the skin with water (better to put the skin in a bag so you don't have to pick up the skin afterwards), add cold water in a bucket then take a bath. Also, it saves money to buy extra ginger. Indeed, you need only the meat of the ginger for making vinegar.
