Cayenne, Capsicum annuum
Cayenne peppers (in fact all peppers) are stimulants to the system. Cayenne stirs up the blood and has an equalizing effect in that it helps to move stagnant blood. It moves blood to the surface, and is a corrector of circulatory problems. Alternately, cayenne will also staunch the flow of blood. If you sprinkle some in a scratch or wound, it will sting, but it will also stop the blood flow.
It has vitamins A, C, and E. You can use small amounts in a tea for colds, flu, and fevers, mix it with chamomile, yarrow, or oregano, and perhaps add a little honey if your throat is sore as well. You can even gargle with it for sore throats, just be sure to use a tiny amount, or heavily dilute it!
Use as a tea with chamomile or peppermint to help with sluggish digestion or flatulence. It will tone the heart muscles and clear the sinuses. Heating cayenne to a high heat destroys its medicinal benefits.
Use with caution, as it is very spicy and will burn if you get it in your eyes or in the tender mucus membranes of the nose (so be careful not to inhale it). I remember all too well cutting up peppers to put into a salsa, washing my hands really well, and at some point later in the day touching my eyes and the burning sensation that ensued (even after some time had passed since I had handled the peppers)! Now I wear gloves when cutting up the fresh peppers for salsas and other dishes.
Another way to get the benefits of cayenne as a blood stimulator, is to take it in capsule form. It will open in the acidic environment of the stomach, which is built to handle tougher situations than our mouths and esophagus are! This way you also avoid getting it in your eyes.
