Cayenne has been used for centuries as a powerful circulatory tonic. The spicy fruit of the plant is used in making the various cayenne preparations. The active ingredient in capsicum and other hot peppers is capsaicin, a natural stimulant. When taken internally, cayenne can help improve poor circulation, indigestion, gas and both physical and emotional fatigue.
Cayenne can also stimulate the heart.
Cremes containing capsaicin relieve pain by effecting sensory nerves. When used externally, cayenne is helpful for the pain of arthritis, strains, sore muscles or joints, bursitis, osteoarthritis, rheumatoid arthritis, and diabetic neuropathy. Apply the cream 4-5 times daily for at least four weeks before assessing its effectiveness. The creme will produce a burning sensation initially but this should decrease with each use. It is very important to either wear gloves during application or to wash hands thoroughly after use.
