Put everything in a small pot, except the honey.
Bring to a boil and then let simmer for about an hour, until the mixture’s consistency is that of syrup.
Remove from heat and let cool.
Strain the solids from the mixture in a mason jar, smashing the solids in your strainer to get all the juices out.
When the mixture has cooled down a bit, add the honey.
Store in refrigerator, keeps for 2 months.
Personally, I take 2 tbsp. per day during cold and flu season.
