Cayenne
Cayenne comes from hot peppers in the Capsicum family and is valued for its naturally occurring capsaicinoids, particularly capsaicin.
Capsaicin is responsible for much of cayenne's characteristic heat and interacts with sensory receptors involved in temperature, circulation and nerve signalling. This gives cayenne a long history of use in warming preparations for circulation, digestion and physical comfort.
Capsaicin and the Warming Response
Capsaicin activates sensory receptors known as TRPV1 receptors.
These receptors respond to heat and other physical stimuli, which explains the characteristic warming or burning sensation associated with chilli peppers.
This sensory response can temporarily increase warmth and local blood flow, particularly when cayenne is used in topical preparations and massage products.
The same mechanism has made capsaicin an interesting compound in research into sensory nerves, metabolism and physical comfort.
Cayenne and Circulation
Cayenne has traditionally been included in herbal formulas aimed at supporting healthy circulation.
Healthy blood flow allows oxygen and nutrients to reach tissues throughout the body, including the muscles, brain, heart, skin and extremities.
Cayenne is often paired with other circulation-focused botanicals such as ginkgo, garlic, hawthorn and ginger, giving each ingredient a complementary role within the wider formula.
Regular movement, exercise and cardiovascular health remain the foundation of healthy circulation.
Digestion and Cayenne
Hot peppers stimulate sensory receptors throughout the mouth and digestive tract.
Cayenne has traditionally been used to support digestion and digestive secretions, although individual tolerance varies significantly.
Some people tolerate chilli and cayenne well, while others experience heartburn, abdominal discomfort or irritation, particularly at higher intakes.
People with a sensitive digestive system should therefore introduce concentrated cayenne cautiously.
Cayenne and Metabolism
Capsaicin has also been investigated for its effects on thermogenesis, appetite and energy expenditure.
Research suggests these effects are relatively modest, and cayenne should not be viewed as a stand-alone weight-management ingredient.
Maintaining a healthy body composition still depends primarily on nutrition, physical activity, sleep, muscle mass and overall energy balance.
Topical Cayenne
Cayenne is also useful in creams and massage preparations.
Applied to the skin at appropriate concentrations, capsaicin activates local sensory nerves and produces a distinctive warming sensation. This makes cayenne well suited to topical products for tired muscles, stiff areas and circulation-focused massage.
Products containing cayenne should be kept away from the eyes, broken skin and other sensitive areas. Hands should be washed thoroughly after application.
Cayenne in O2B Products
At O2B Healthy, cayenne is included in O2B Circulation+ alongside ginkgo, garlic, hawthorn, ginger and vitamin C to support healthy circulation and cardiovascular function. It is also used in O2B NRG-FX as part of an energy and performance formula and in O2B Lung Health for warming respiratory and circulatory support. Topically, cayenne is used in O2B Circulation Boost and O2B Move Well, where its warming action complements massage and other botanical ingredients.
