When herbs are described as "tonics" what it simply means is that this herb is good for use in revitalizing, strengthening and healing the body towards an energized and rejuvenated state. Thus, mixtures, and often times drinks, which held these properties, have been referred to as "tonics."
Personally, I think Ginger tastes yummy and Ginger and Honey are excellent together, and I would just make a tea. Steep Ginger Root (available from the Bulk Herb Store) for 20-25 min. Add honey to taste.

You can also make a syrup out of ginger and honey. Boil 2 cups water, remove from heat, add fresh ginger while water is still boiling. Let steep, covered for 12 hours. Strain ginger out, squeezing juices out before discarding. Add Ginger Water to a jar of honey. Shake well. Let stand, covered, in a cool, dark, dry place, for 5 days, shaking twice a day. You now have a very healthful syrup good for all kinds of things.
