Cut about one inch from a ginger root, peel it and grate it straight into a kettle. (You can keep the rest of the cut ginger root in a fridge for a few weeks, thanks to its antibacterial effects.) Pour boiling water over the grated ginger, you can also add cinnamon and/or clove. You can also let it boil for half a minute or a minute in a microwave to extract the essential oils from ginger better, but not for too long not to destroy the oils. Filter the ready tea and if you wish, you can add some honey and lemon or orange juice. If you cool the tea, you get some kind of ginger ale. I recommend ginger ale to be made without clove and cinnamon and to add more sugar and lemon juice, but it depends mostly on your own wishes.
