In a small pot, combine the water and ginger, along with the garlic, cinnamon sticks, and/or star anise, if using.
Bring to a boil then reduce heat and simmer, covered, for 15 minutes.
Remove from heat and strain.
If you're infusing your brew with herbal tea, add it to the water now and allow to steep (covered) for 3-5 minutes.
Strain out the tea and add the lemon juice.
Sweeten to taste with honey and stir in cayenne, if using, before serving.
Keep sipping on a steady supply of cold and flu brew while watching funny movies until you feel better.
The only mandatory ingredients for this tea are ginger, lemon, and honey. Feel free to add as many or as few of the optional ingredients as you'd like. The herbal tea is also optional. See the post above for suggestions.
