This little spice isn't useful just for making your mouth feel like fire. It's long been hailed as a miracle working substance. In most circumstances, cayenne pepper can stop bleeding in less than a minute. When applied to a wound, cayenne pepper reacts with the body and equalizes blood pressure. Blood clots quickly when pressure is equalized.
It also has a lot of other uses: it can help bleeding internally too if you take a teaspoon of it. It's also said to improve blood circulation, assist in digestion, stimulate perspiration and saliva and help lessen pain from swollen joints and limbs.
