Cayenne pepper powder is ground from dried cayenne chili peppers (Capsicum annuum). The powdered form stores well and mixes easily into food and drinks, unlike fresh peppers or oleoresin.
The capsaicin in cayenne stimulates digestive secretions and supports healthy circulation and metabolic function. Some people use the powder for its mild thermogenic effect, looking for a modest boost in energy and metabolism.
Mix the powder with water or juice, often warm water with lemon, or take it in capsules. Use it as a culinary spice. Take it with meals to aid digestion or in the morning for an energizing lift.
Cayenne can irritate the stomach and digestive tract. Begin with small amounts and skip it if you have active heartburn, ulcers, or inflammatory bowel conditions. The powder may interact with blood pressure medications and anticoagulants, changing how those drugs work.
