Biochem/physiol Actions

(-)-Umbellulone, isolated from the"headache tree" Umbellularia californica Nutt, is a selective activator of Transient Receptor Potential Anykrin 1 (TRPA1) channels. (-)-Umbellulone activates TRPA1 channels on nociceptive trigeminal afferents, resulting in release of CGRP and CGRP-mediated neurogenic vasodilatation, causing a painful cold sensation and headache/migraine.
