Capsaicin is a capsaicinoid that causes a cutaneous neurogenic inflammation after activation of the vanilloid receptor subtype 1 (TRPV1) with generation of substance P (SP) and calcitonin gene related peptide (CGRP) and release of proinflammatory mediators, such as BK, histamine, 5-HT, and PG [47,48]. This evidence concerns the gene TRPV1 and inflammatory response.
