Cayenne is the most useful of the systemic stimulants. It regulates the blood flow, equalizing and strengthening the heart, arteries, capillaries and nerves. It is a general tonic and is specific for circulatory and digestive system. It may be used in flatulent dyspepsia and colic. If there is insufficient peripheral circulation, leading to cold hands and feet and possibly chilblains, Cayenne may be used. It is used for treating debility and for warding off colds. Externally it is used as a rubefacient in problems like lumbago and rheumatic pains. As an ointment it helps unbroken chilblains, as long as it is used in moderations.
