Eating a teaspoon a day of raw local honey can help build your immunity and combat allergies. Raw local honey contains natural and safe antiobiotic, antibacterial, and anti-inflammatory properties. You can find raw local honey at your local health food store. (Please do not give honey to children under one years old.)
In addition, another way to combat allergies is to receive regular acupuncture treatment which brings your entire body into balance and therefore increases your immunity.
