Cayenne pepper is widely known for its red appearance and extremely spicy nature. After all, a little of this can go a long way. In addition to being a potent spice, cayenne (and other spices) can actually be a major player in the elimination of allergies. Due to certain anti-histamine and anti-inflammatory compounds in the spice, cayenne is definitely worth a shot if you have been suffering from allergies for a period of time. Consider adding a teaspoon or so to your morning smoothie in the morning or simply mix cayenne in fresh water and lemon and drink it throughout the day for best results.
