i got a mix from my midwife but i don't remember all the ingredients... i know it included calendula flowers, and later when I had sore spot, my midwife recommended i use hot chamomile teabags as compresses... I also put lavender and tea tree oil in my baths and took lots of vitamin C, arnica and aloe are also good for healing...
Calendula flower, lavender, chickweed, plantain, st john's wart. I make it myself in equal parts and then steep it, like an infusion, then dilute it for whatever purpose. For a peribottle it's 1:1, but for a sitz bath it's more dilute.
I haven't had a child, but when I had to have my rectum and anus removed, due to colitis, I found that Earth Mama Angel Baby New Mama Bottom Spray helped with the soreness quite a bit. My incision from this surgery was almost identical to an long episiotomy, so my doctor suggested that I use the same products that were for postpartum. I also used special maxi pads that had an ice pack built into them, that you pop like an ice pack and they stay cold for hours.
This spray cooled the incision site very well. You can even keep it in the fridge to make it even more cooling. I also used their PostPartum Bath Herbs, but prefered the bottom spray better.
