I actually looked at calendula, and I think I found studies of it’s efficacy in some random cream being tested. To actually make it into the cream they first extract oil from the plant in this process similar to the process of rose absolute extraction, if I remember right. (If anyone wants, I can relook all this up, but I have decided my links have just been overkill as of late.)
I know that is not what you asked about Doffy90, but I figured if it gave you more information to google more information- I would write it. It just so happens I was looking that specific herb earlier this week. However, I would expect that an infusion of calendula mixed with say, err, Idk, lavender, delivered in an Aloe Gel would work differently than just the calendula in an aloe gel. You gotta take into consideration it’s chemical, errr, or it’s substance interactions, even if the substance’s have similar traits, you can’t predict what you’ll get on the skin until you test.
At least in theory, I think… I could be WAY off. I’m skeptical of hippies too, but always curious.
