This fiery herb is great for regulating blood flow and for toning and strengthening the heart, arteries, capillaries and nerves. Cayenne stirs up the blood, pushing it the body’s surface and extremities. This means that despite its hot, fiery nature, cayenne can cool the body by dispersing trapped heat and promoting sweating. Its ability to stoke the body’s metabolic fires make it a useful ingredient in blends for weight loss. It may also be used in flatulent dyspepsia, but should be used with caution or avoided in cases of acid reflux or heartburn. Cayenne is also high in vitamin C.
