Counterirritant
Substance which creates inflammation
A counterirritant is a substance which creates irritation or mild inflammation in one location with the goal of lessening discomfort and/or inflammation in another location. This strategy falls into the more general category of counterstimulation.
Topical counter-irritants are non-analgesic, non-anesthetic substances or treatments used to treat pain. Capsaicin, menthol (mint oil), methyl salicylate, and camphor are examples of counterirritants. Heat and cold therapy and massage relieve pain by counterstimulation.
The US Food and Drug Administration defines a counterirritant as "An externally applied substance that causes irritation or mild inflammation of the skin for the purpose of relieving pain in muscles, joints and viscera distal to the site of application. They differ from the anesthetics, analgesics, and antipruritic agents, however, in that the pain relief they produce results from stimulation—rather than depression—of the cutaneous sensory receptors and occurs in structures of the body other than the skin areas to which they are applied as for example, in joints, muscles, tendons and certain viscera.

Why this record matters
“Counterirritant” is worth following because a concise public description often conceals a longer documentary argument. Here, Counterirritant, Substance and creates provides the most credible route into that argument.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jan 7, 2026. The linked authority identifier is Q3458430. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
