Hi friends, Lately I'm having pretty good success against undefined headaches and even my tinnitus by using Cayenne pepper. I stir a tea-spoon of Cayenne pepper in a glas of apple juice and drink it. It's pretty amazing, and works almost instantly. It is said(I don't know if it's scientifically proven) that Cayenne pepper regulates the heart rythm, whether it's too slow, or too fast. It has the ability of thinning the blood. What I experienced too, is when I take it before going to bed, I sleep much better. Maybe a worth to try. Best wishes, OS.
