Ginger rhizome is well known to help with upset stomachs -- even today many people go for commercial ginger ale when nauseous. To make a more concentrated brew, cut up the ginger rhizome and boil with water to make a spicy tea that can offer even more benefits.
Photography weblog Snap Shots and Tips recommends this simple family recipe for ginger tea: Wash and peel an entire ginger rhizome and cut it into small slices. Add those to a pan along with two-three cups of water and bring to a boil. You'll know it's ready when the water reaches a pale yellow colour. Pour it into a mug and add a teaspoon of honey or brown sugar.
This tea will have a spicy ginger flavour that I find very comforting.
