Water-based remedies include, teas, infusions, decoctions, poultices, compresses, soaks, baths, and fomentations.

I use comfrey leaf internally and externally.

I use comfrey root externally only.

Comfrey Leaf Tea: steep 1-3 teaspoons of fresh or dried comfrey leaf in a cup of boiling water for 3-5 minutes. 

Add honey to increase soothing qualities.
