I can tell you what my midwife suggested i use.
Steep the following overnight: 1 handful of herbal mixture per quart of water
comfrey- aids healing and new cell growth
sheperd's purse- aids in blood clotting
rosemary- great for swelling
uva ursi- heals the urinary tract
garlic- an antiseptic, can be added
strain through cheese cloth. pour infusion to fill large bowl or sitz bath. relax 20 mins a couple times a day
I don't have an exact measurement of each. I just went out and bought them today, i think i will do equal amounts. not sure i will use garlic, if i do probably just a small amount.
It is so much cheaper to buy them in bulk. I also bought extra comfrey to soak pads and then freeze.
hope this helps. i'm sure there are different recipes people use
