That is a common experience. And this is what Dr. John Christopher has to say about this: “This herb is a great food for the circulatory system in that it feeds the necessary elements into the cell structure of the arteries, veins and capillaries so that these regain the elasticity of youth again and the blood pressure adjusts itself to normal. When the venous structure becomes loaded with sticky mucus, the blood has a harder time circulating; therefore, higher pressure forces the liquid through. Cayenne regulates the flow of blood from the head to the feet so that it is equalized; it influences the heart immediately, then gradually extends its effects to the arteries, capillaries, and nerves.”
