In veterinary practice, what does a counter irritant typically do?

A counter irritant is a substance that, when applied to the skin, causes irritation or inflammation in the area where it is applied, which in turn stimulates circulatory responses to that area. This can be beneficial as the increased circulation brings more blood flow, which can facilitate healing by delivering more oxygen and nutrients while also removing metabolic wastes. The stimulation of circulation can lead to a reduction in deeper tissue discomfort by drawing attention away from the underlying injury or issue, thereby providing a form of pain relief.

While counter irritants might indirectly lead to decreased inflammation or relief of pain as a result of increased circulation, their primary function is rooted in the stimulation of blood flow to the affected area. This characteristic distinguishes counter irritants from other pharmacologic agents that may target sedation directly or address pain and inflammation more systemically.
