Both are pretty basic...
I have an allergy to lanolin (have to wear gloves while spinning/knitting with wool, my elbow test patch with Lansinoh blistered, etc) so I make my own lip balms/body balms/nipple cream to avoid problems.
The nipple cream is basically 1 part beeswax to three parts extra virgin olive oil. The wax comes from a friend (and I know her hives) and while I did extensive research into the potential for Clostridium botulinum growth in beeswax, the risk of anyone developing botulism from consuming small amounts of beeswax is apparently so small the benefits of having a nipple cream I could actually use won the day. However, you can wipe/wash the cream off before nursing (if any residue remains) until you introduce honey products. (keeping in mind that c. botulinum is also found in things like dirt so keeping a totally "clean" environment is a bit...well...not possible
I also made a cream for a vegan friend that was 1 part coconut butter to two parts shea butter. She didn't wipe it off but I probably would since I had to get the butters from the co-op and didn't know exactly how they had been processed/how long they'd been on the shelf.
For the sitz bath I blend 2 cups of epsom salt or sea salt, a cup of dried comfrey, a quarter cup dried lavender flower, a quarter cup of dried calendula, a quarter cup of fresh grated ginger or a half cup of dried ginger. If I use the dried ginger I just make up a big batch and keep it in a jar by the sitz bath. If I use fresh then I add the grated ginger to the sitz bath as I make it.
I keep an electric kettle in the bathroom and "brew up a tea" as necessary. Usually a scoop or two of the mix with hot-to-touch water... I don't generally bother straining the tea out since I rinse off after the sitz bath using the sprayer, but you could make a whole batch/strain it each day and then heat as needed. And I do strain it into the peri bottle since the squishy herb mash clogs the peri bottle spray opening.
My routine (following a 4th degree tear) was a 10-15 minute sitz bath followed by comfey infused honey or pure aloe gel spread on the tear followed by "sunning" (laying on the bed with my bum in a sun beam for 5-10 minutes). I did that at least 4 times a day (I'd even nurse dd2 while sitting on the bath, then while she slept I'd do the aloe or honey and the sunning). I could really feel the difference if I skipped a sitz bath or didn't use the honey or aloe for a day.
