Hi Ruth! I’ve been experimenting a little bit with peonies this year. You could use the petals for infusions, but I haven’t really been able to find any skin or health benefits they offer in my research. White peony root is used in Chinese medicine, I believe I’m remember right anyway, so there may still be a connection I haven’t found yet. Admittedly, I’ve been so busy with other projects and this busy time on the farm, the research on peonies has been shallow! :) You could definitely add them for a label appeal type thing though, if you sell products. They are considered safe and edible, so I’d love to find ways to use them more.
