Abstract: This article is an educational review about the fundamental aspects related to the proposal of the existence
of a peripheral sympathetic reflex regulated by histamine, through its effect on presynaptic H3 type receptors,
under the interaction of a sensory neuron that would be mediated by Substance P. In this respect, we consider
it useful to highlight the role of histamine, so we discuss some aspects about its history, metabolism, and
function, as well as its interaction with H3 type receptors that are considered as neuroreceptors, which define and
typify it as a neuromediator at both levels of the nervous system, central and peripheral.
