Add the dried herbs to your jar. Pour in the glycerin and water and stir to combine.
Wipe the jar rim and put the lid on.
Place a wash cloth or silicon baking mat (to keep jar from breaking) in the bottom of a crock pot with a “keep warm” or very low setting. Fill the crock pot up with water to cover 3/4 of the jar (don’t cover the lid!) and turn on the lowest setting.
Keep in the slow-cooker for at least 1 day on this setting, adding water as needed. I’ve done up to three days.
If you prefer to use the stovetop, then place a wash cloth in the bottom of a pot and place the jar on top. Fill the pot so the water covers about 3/4 of the jar. I use a pot that’s deep enough for me to do this and also put the pot lid on. Simmer gently for 2-3 hours.
Once the mixture is cool, use a cheesecloth to strain out the herbs. Squeeze the cloth to get out as much liquid as possible.
Store the glycerite in a clean dropper bottle or jar.
Notes
When made and stored properly, glycerites have a shelf life of 2-3 years.
