Add the ginger and water to a small saucepan and bring the mixture to a boil.
Reduce the heat to simmer and let it simmer for 30 to 45 minutes. You want the liquid to reduce to 1 cup so put the saucepan lid partially on to allow some steam to escape.
Strain out the ginger pieces and pour the ginger infusion into a heat safe glass jar. A Mason jar works well for this. If you have more than 1 cup simmer it down some more. If there's less than 1 cup then add more water to make 1 cup.
Stir in the raw honey.
Store the ginger syrup in the fridge. This will last for about 2 weeks or it can be frozen for longer storage.
Notes
Add other herbs as desired with the ginger while it simmers. See the above article for suggestions.This syrup is very thin. If you want a thicker syrup you can simmer the honey with the ginger, but then it won't be raw.
