Peel and slice the fresh ginger, about 1/8 inch thick.
Add dried elderberries, water, ginger, and cinnamon to slow cooker.
Cook on LOW for 8 hours.
When done cooking, pour into a large mixing bowl and allow to cool.
When liquid is cool, stir in the honey until dissolved. Pour through a mesh strainer into a mason jar. Use the back of a large spoon to squeeze out any remaining juice from the berries.
