Cayenne pepper has been used for thousands of years as a medicinal herb. It improves circulation and blood flow, aids digestion, and can help treat pain, inflammation, heart conditions, and bleeding. Cayenne is particularly effective in emergency situations, as it can help stop heart attacks and bleeding quickly. The active compound capsaicin is responsible for many of cayenne's health benefits, such as reducing platelet stickiness and relieving pain. Cayenne is considered one of the most powerful and useful herbs for its effects on the circulatory, digestive, and immune systems.
