resiniferatoxin
noun1
- A naturally occurring ultrapotent capsaicin analogue (having in its pure form a Scoville heat unit measure of 16,000,000,000) that activates the receptor TRPV1 (aka vanilloid receptor 1 or the capsaicin receptor) in a subpopulation of primary afferent sensory neurons involved in nociception.
- They both cause an initial stimulation and inflammation, capsaicin much more so than resiniferatoxin. — 2010
