I thought I had posted a photo of some herbs that I had infusing in organic olive oil... But I can't find it.
Anyway, about 7 weeks ago, I put a jar of herbs and olive oil in the window sill (chamomile, yarrow, comfrey) and shook it every few days.
Some of my kids have dry skin and rashes during the winter and neem oil seems to work well on it.
So I strained the olive oil, added cold-pressed neem oil and beeswax (I eyeball it, but about 1 part beeswax to 3 parts oil) and heat just until the beeswax is melted.
Even with lavender essential oil, you can still smell the neem oil a lot...but it works so well that we don't mind the smell. ;)
