Cayenne pepper (Capsicum annuum) is a medium-hot chili pepper, renowned for its vibrant red color, slim, elongated shape, and spicy heat. The peppers are typically 4-6 inches long and taper to a sharp tip. They are commonly used fresh, dried, or ground into powder for culinary purposes. Rich in capsaicin, cayenne peppers are not only a flavorful addition to dishes but also valued for their health benefits, including boosting metabolism and reducing inflammation.
