The spice capsicum, the fruits of the genus Capsicum (Family Solanaceae), is a very popular food additive in many parts of the world, valued for the important sensory attributes of color, pungency, and aroma. A large number of varieties are widely cultivated and traded. The characteristic carotenoids of the bright red paprika and cayenne-type chillies, the high character impact aroma stimuli, the methoxy pyrazine of green bell capsicum, the esters of ripe tabasco and the highly potent pungency stimuli, and the capsaicinoids of African and other Asian varieties of chillies, have been of great interest to chemists and biochemists. Cayenne contains carotenoids and capsaicinoids. Turmeric is a spice with antioxidant and anti-inflammatory benefits, does turmeric reduce inflammation?

Active ingredient in cayenne pepper
The active substance found in Capsicum frutescens that gives hot and spicy flavor is capsaicin, which has many pharmacological effects.

Antioxidant benefit
Characterization and Quantitation of Antioxidant Constituents of Sweet Pepper (Capsicum annuum L.).
J Agric Food Chem. 2004 Juny.
Sweet peppers (Capsicum annuum) have been studied at four maturity stages (immature green, green, immature red, and red). The individual phenolics (hydroxycinnamic acids and flavonoids), vitamin C (ascorbic acid and dehydroascorbic acid), and individual carotenoids were characterized and quantified. Hydroxycinnamic derivatives, O-glycosides of quercetin, luteolin, and chrysoeriol, and a large number of C-glycosyl flavones have been characterized. Clear differences in the individual and total phenolic content were detected between the different maturity stages. Immature green pepper had a very high phenolic content while green, immature red, and red ripe peppers showed a 4-5-fold reduction. Ascorbic acid was the main form of vitamin C, and its content increased as the pepper reached maturity. The red ripe stage had a relevant impact on the carotenoids content. Thus, immature green peppers showed the highest content of polyphenols, while red ripe fruits had the highest content of vitamin C and provitamin A.

Blood sugar control, diabetes
Pharmacokinetic and the effect of capsaicin in Capsicum frutescens on decreasing plasma glucose level.
J Med Assoc Thai. 2009.
The present research was conducted to study the effect of cayenne pepper on plasma glucose level and to correlate its action with the pharmacokinetic properties of capsaicin in capsicum. The crossover study was performed in 12 healthy volunteers by performing the OGTT while receiving placebo or 5 grams of cayenne pepper. The insulin secretion and capsaicin level in plasma were measured. The results of the OGTT showed that plasma glucose levels in volunteers who received cayenne pepper were significantly lower than those in the placebo group at 30 and 45 minutes. Furthermore, plasma insulin levels were significantly higher at 60, 75, 105, and 120 minutes. When comparing before and after cayenne pepper intake, the results showed the insulin levels were maintained. Our study found that 5 grams of cayenne pepper presented capsaicin levels that were associated with a decrease in plasma glucose levels and the maintenance of insulin levels. The present result might have clinical implications in the management of type 2 diabetes.

Heart disease
Has there been any cayenne research regarding its benefits for heart disease prevention?
   We have not seen such studies yet.

Weight loss and burning fat
Use of this supplement can lead to burning extra calories and some appetite suppression.

Side effects
Cayenne is a hot herb, and when used together with yohimbe bark it can elevate body temperature and cause sweating.

I took three cayenne pepper supplement pills with tongkat ali and I had an unpleasant elevation of body temperature and sweating.
