1. Combine sage and cayenne with water. Bring to boil, then reduce heat and simmer, uncovered, until liquid is reduced by half.
2. Let cool enough that you can work with it. Strain liquid and press sage to extract as much liquid as possible.
3. Add honey, to taste, and lemon juice. Store in refrigerator and take 1 tablespoon or more often as needed at the onset of sore throat or upper respiratory infection.
