my MW gave us comfrey leaves - so that's what you want. I made these last night, while explaining about 25 times to my DD's what I was doing. They thought it was gross! I'm actually looking forward to it because I remember how wonderful it actually felt!
1/3 cup (approximately) comfrey
1 1/2 cup water
at least 10 4x4 sterile gauze pads
Simmer/boil/heat for at least 10 minutes - I left if for half hour or so.
When it cools down, dip 4x4 gauze pads into the mixture, get them all goopy, then freeze individually in plastic baggies. The leaves will be messy when you use these pads, but they add a benefit, so don't strain it unless you're grossed out by the idea of leaves on your girly bits ...
My frugal nature kicked in here, and I didn't want to go buy sandwich bags for this, but I do have about 100 snack-size bags, but they were too small, so I layered the gauze pads between the tiny plastic bags - stacking them all on a cookie sheet. Eventually, I'll put them all into a bigger plastic bag. (my theory was based on how you would freeze fruits or pancakes - I hope it worked!)
I doubled the recipe, which is why I had so much leftover - pregnant brain
