  Capsaicin - Wikipedia, the free encyclopedia
Capsaicin and several related compounds are called capsaicinoids and are produced as a secondary metabolite by certain plants of the genus Capsicum (chile peppers), probably as deterrants against herbivores.
Since capsaicin in its pure state is poorly soluble in water, but good in fat, oils, and pure alcohol, an often-heard advice is to eat fatty foods like buttered bread or beverages like whole milk or whipped cream, assuming that these would carry away the capsaicin and thus reduce the source of the burning.
Capsaicin is used in topical ointments used to relieve the pain of peripheral neuropathy (for example post-herpetic neuralgia).

 Capsaicin - Supplements
In addition to the "confusion" that capsaicin induces in sensory nerves, it also results in a temporary depletion of neurotransmitters from sensory nerves — an effect that reduces the ability of the nerve to sense pain in other areas of the body.
Capsaicin creams and supplements can not only cause a mild burning for the first few applications, but it can also cause severe discomfort if you get it in the wrong place (like your eyes).
Caution should be used during pregnancy (to avoid gastrointestinal irritation) and lactation (because capsaicin may pass into breast milk and cause the milk to be unpalatable to the infant).

This integration is the reason eating foods containing capsaicin are perceived as being "hot." Capsaicin’s effect of depleting cell stores of the pain producing substance P and causing cell death evokes a gradual desensitization to the nociceptors stimulation, thus causing a numbing effect in the area of targeted sensory neurons.
Capsaicin is the common name for (8-methyl N-vanillyl 6nonamide), the chemical component most well known for its inhabitance in the internal white ribs of chili peppers and its ability to produce the burning hot sensation of chili-laced spicy foods.
Capsaicin’s ability to evince the same sensation as excessive heat or mechanical abrasion could thus be explained by thinking of it as chemically mimicking the actions of a physiological stimulus or an endogenous ligand produced on account of tissue injury.

Capsaicin had a general stimulatory effect on metabolism, similar to that of epinephrine; oxygen consumption was elevated, respiratory quotient was initially elevated, then decreased; and serum glucose and insulin levels were elevated, concomitant with a rapid decrease in liver glycogen, and a gradual increase in serum triglycerides.
Capsaicin elicits a vasoconstrictive response in the large cerebral arteries of the cat (Saito et al., 1988), and in the middle and basilar cerebral arteries, an effect was attributed to a direct contraction of smooth muscle, since the response was independent of the presence of endothelium and nerve components.
Capsaicin at pH 7.4 increased the conversion of glucose to lactic acid, indicating a stimulatory effect on glucose metabolism; however, at the lower pH value of 5.0, glucose metabolism was suppressed with a concomitant increase in glucose transport across the intestinal wall.

 Facial Neuralgia Resources:  Capsaicin Use for Oral Pain
Capsaicin and its analogues are the active (hot) ingredients in chili peppers that produce burning pain by stimulating polymodal nociceptors, the predominant pain receptors found in skin and mucous membranes.
The receptors are described as polymodal because they are multiply sensitive to noxious heat and mechanical and chemical stimuli.[26-28] It has been demonstrated experimentally that after ingesting capsaicin-containing foods or after capsaicin application to the oral mucosa, the severity of pain is directly proportional to the concentration of capsaicin present.
Theoretically, when the concentration of capsaicin is increased to produce burning pain approximately equal to a patient's mucositis pain, mucositis pain may diminish or disappear as the sensation from capsaicin dissipates.

 Harvard Gazette: Using chili peppers to burn drug abusers
Capsaicin, the chemical responsible for the "hot" in peppers, acts on a protein that also responds to the heat and high acidity associated with painful inflammation in the joints and skin.
In human volunteers, intravenous administration of capsaicin produces a widespread burning feeling of the chest, face, rectum and extremities as well as paroxysmal coughing." Otherwise, capsaicin appears to be safe.
Capsaicin works by hitting on a protein known as TRPV1, which transports its fiery message into the nervous system via sensory nerves in the mouth and other areas.

 Neurogesx: NGX-4010
Capsaicin appears to work by activating a membrane protein expressed on specialized dermal nerves (nociceptors) called the transient receptor potential vanilloid 1 (TRPV1), a ligand-gated ion channel that is highly calcium permeable.
Persistent activation of TRPV1 by an agonist such as capsaicin or trans-capsaicin permits high levels of calcium to enter the nociceptor, thereby raising intracellular calcium to a level that can result in extended impairment of nerve function.
In an open-label multicenter study of 12 patients with painful HIV-associated neuropathy, patients treated with a 1-hour dermal application of high-concentration trans-capsaicin to the most painful areas of the feet reported a mean decrease from baseline in “average pain for the past 24 hours” of 40% (Figure 2).

 Scoville scale - Wikipedia, the free encyclopedia
These fruits of the Capsicum genus contain capsaicin, a chemical compound which stimulates thermoreceptor nerve endings in the tongue, and the number of Scoville heat units (SHU) indicates the amount of capsaicin present.
As originally devised, a solution of the pepper extract is diluted in sugar water until the 'heat' is no longer detectable to a panel of (usually five) tasters; the degree of dilution gives its measure on the Scoville scale.
Conversely, the hottest chiles, such as habaneros, have a rating of 300,000 or more, indicating that their extract has to be diluted 300,000-fold before the capsaicin present is undetectable.
