Good morning @perry1970 and welcome to Mayo Clinic Connect! You’ve really jumped in with both feet! I’m so glad that you’re helping other members. I’ll see if I can find and post the info about Nigella sativa cream
https://www.sciencedirect.com/science/article/abs/pii/S0273230021002294#:~:text=Nigella%20sativa%20seed%20has%20been,is%20valid%20only%20when%20N. This article talks about Nigella sativa (black cumin) having a long history as a food additive and therapeutic agent. It didn’t mention side effects, so, as a caution, i would suggest clearing it with your doctor.
How did you find Connect?
