Indeed. Shots of pure ginger juice are great, too. The remaining "dry" pulp goes well blended with a little honey and softened butter as a makeshift spread.
I try to aim for 7-10 cups a day when sick, apart from other fluids such as electrolyte solution.
I also find the broth of some clear soups (that may contain ginger and perhaps chilli) to be excellent for that purpose, as well.
And sucking on those thumb sized chunks of ginger is very good for colds and sore throats.
