Place all the herbs in a quart-sized glass jar.
Pour the honey into the jar on top of the herbs.
Pour the vodka into the jar on top of the honey.
Stir the mixture well until all the herbs are completely saturated.
Place a lid on the jar and allow the mixture to steep for 2-6 weeks. I found that 4 weeks is sufficient.
Over the course of the stepping period, remove the lid on the jar and stir the mixture well. Replace the lid.
After the steeping period has finished, place a fine mesh strainer over a large measuring cup or bowl and pour the mixture through the strainer. Do not press on it.
Once the mixture stops dripping into the large measuring cup or bowl, strain it a second time through a clean fine mesh strainer into a clean large measuring cup or bowl.
Transfer the strained content to a dark-colored bottle (or bottles) with tight-fitting lids and store in a cool, dark, dry area.
This herbal elixir has an infinite shelf life because it is made with alcohol. However, if it ever takes on an off odor or develops any type of mold or other form of growth, discard it immediately.
When you feel the symptoms of a cold or flu coming on, take one teaspoon per day of this elixir up to three times per day. You can take this directly from a spoon or mix it with a small amount of water or juice.
