I worked at an Ayurveda Center for a while, and learned about ginger root. It's great.

If your grocer sells ginger root in the produce section, buy a few inches, cut a few pieces and boil it in water for a few minutes. Then, drink that like a tea. Keep a thermos full, maybe.

Or, look for ready-made ginger tea...Alvita sells it, and they have a website.

Some people don't peel ginger root, but, I do peel it. (Still arguing about that one.)

If you have a juicer -- you can juice the ginger, and add an equal volume of honey, and drink about a tablespoon or two of that. It's very strong, warms the stomach and may help get rid of a cough. (At the Center, we added something else, black salt maybe, but I can't remember.)
