A unique potassium channel opener from rosemary!

Congratulations to Rian Manville and Derk Hogenkamp for their paper out today in Communications Biology reporting the unexpected ability of rosemary and its constituent carnosic acid to selectively open KCNQ potassium channel isoforms in the brain. The finding may give clues to the centuries-old use of rosemary as a memory aid and for other neurological applications.
