The burning and painful sensations associated with capsaicin result from "defunctionalization" of nociceptor nerve fibers by causing a topical hypersensitivity reaction in the skin. [ 2 ] [ 42 ] As a member of the vanilloid family, capsaicin binds to a receptor on nociceptor fibers called the vanilloid receptor subtype 1 (TRPV1).
Pepper spray, oleoresin capsicum spray, OC spray, capsaicin spray, mace, or capsicum spray is a lachrymator (tear gas) product containing the compound capsaicin as the active ingredient that irritates the eyes to cause burning and pain sensations, as well as temporary blindness. Its inflammatory effects cause the eyes to close, temporarily ...
Bengay and similar products, such as Flexall, Mentholatum, Capzasin and Icy Hot, variously contain menthol, methyl salicylate (oil of wintergreen), and capsaicin as active ingredients and have a potential to cause first-to-third-degree chemical burns. [4] [5] Some people have been hospitalized after receiving such burns. [4]
Hunan hand syndrome (also known as "chili burn" [1]) is a temporary, but very painful, cutaneous condition that commonly afflicts those who handle, prepare, or cook with fresh or roasted chili peppers. [1] It was first described in an eponymous case report in The New England Journal of Medicine in 1981. [2]
The heat, or burning sensation, experienced when consuming hot sauce is caused by capsaicin and related capsaicinoids. The burning sensation is caused by the capsaicin activation of the TRPV1 heat and ligand-gated ion channel in peripheral neurons. [18] The mechanism of action is then a chemical interaction with the neurological system.

However, because of an initial burning effect of all natural vanilloid receptor agonists, including capsaicin, therapy becomes complicated and perhaps ineffective. Attempts to make synthetic agonists with good separation between excitatory effects and the analgesic effects have not been successful. To avoid this persisting side effects of TRPV1 ...
