The landmark paper discussed in this chapter, published by Davis et al. in 2000, describes the role of the capsaicin receptor, which is called transient receptor potential cation channel subfamily vanilloid member 1 (TRPV1), in inflammatory thermal hyperalgesia. Capsaicin, the pungent agent found in hot peppers, has been linked to pain for centuries because it induces a burning pain sensation which, after prolonged application of the agent, turns into analgesia. Because of this, capsaicin has been used to relieve pain, most likely since prehistoric times. The elucidation of the role of TRPV1 in nociceptive processing was heralded as the starting point for the development of agents which would revolutionize pain management. Unfortunately, that promise is yet to be realized and apparently we need a more detailed understanding of the role of TRPV1 in physiological and pathological processes in order to fulfil the analgesic potential of drugs acting on this receptor.
