What is the active ingredient in OC known as?

The active ingredient in Oleoresin Capsicum (OC), a common component in pepper spray, is capsaicin. This compound is responsible for the characteristic heat that is associated with chili peppers. Capsaicin works by binding to the TRPV1 receptors in the nervous system, which are responsible for sensing pain and temperature. This interaction creates a burning sensation, which can incapacitate an individual when used in defensive situations, making it an effective tool for self-defense and law enforcement.

Understanding this is crucial for individuals handling OC spray as it emphasizes not only its defensive use but also the physiological effects it can have on both the attacker and the user. The other options, while related to chili and pepper plants, do not specifically refer to the primary active constituent that gives OC its potency in defensive scenarios.
