Comfrey Leaf infusion

The left jar is an infusion Kay made last night. She used dried comfrey leaves and boiling water. It sat all night and then she strained the plant matter out of it. We had about a 1/2 cup this morning. It tasted pretty bad. She added some fresh chocolate mint leaves and sugar - that helped, but its no Crystal Light.

* Does anyone know if it is okay that we also used the stems of the comfrey for this? 

The jar on the right is some catnip tea she made. She picked fresh catnip leaves (and a few chocolate mint leaves) and put them in our teapot. Then poured water that had boiled on top and let it sit for 20 minutes. It didn't taste much better than the comfrey but sugar helped a lot. I think I like the teas better cold.
