How to make ginger herbal tea: to make a ginger herbal tea, proceed as follows: cut into thin slices (or small cubes) about 10 g of fresh root without any external skin, let it boil in water for 7/8 minutes, turn off the heat and filter it. Alternatively you can prepare an herbal tea with dry ginger, the procedure is the same but use about 1 gram.
