This is a spice and citrus tea, rather than a herbal one, and it makes a wonderful tonic when you feel a cold coming on.
You will need:
Root ginger, lemons, honey, whiskey.
Slice or finely chop a two-and-a-half centimetre piece of root ginger and put it into a large mug with two strips of lemon zest or a couple of slices of lemon, a teaspoonful of honey and a dash of whiskey and top it up with boiling water. Allow it to infuse and drink it while it is still hot.
