Place berries and water in a medium sized pot on the stove. Bring to a boil over medium-high heat, then turn down to la very low simmer for about 5 minutes.
Use a strainer to pour the liquid into a bowl or glass jar (I use a large mason jar or an empty 32 oz juice jar with a large funnel placed over the opening).
Add the honey and whisk (if in a bowl) or place the lid on the jar and gently turn/shake until honey is mixed in (I wrap a kitchen towel around the jar to protect from the heat). Store in fridge.
To serve, pour 1 oz per child or 2 oz per adult into a glass 4-5 times/day. Can dilute each "dose" with water if preferred.
Notes
This mixture freezes well - just be sure there's plenty of room at the top of the jar for expansion. To defrost, place in the fridge for 24 hours.
If giving to children less than 12 months old, omit the honey.
