Eledoisin

A peptide extracted from the posterior salivary glands of certain small octopi (Eledone spp., Mollusca), or obtained by synthesis. Its actions resemble those of SUBSTANCE P; it is a potent vasodilator and increases capillary permeability. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1364)
