Put the marshmallow root in ¼ cup of water and let it steep through a cold infusion.
Boil the rest of the water in a teapot or kettle. Add the elderberries, chamomile, and lavender into a jar and fill it with the remaining boiling water. You can also boil the water with the herbs on the stove as well if you prefer that way.
Let both jars sit for 10-15 minutes.
Strain both jars and combine the water.
Pour the liquid into the silicone mold and put it in the freezer. Let sit overnight or until solid.
Take out the tea bomb and pour hot water over it and enjoy a nice cup of tea!
