Allergic reactions are caused when the body tries to compensate for environmental circumstances. Adding herbs to her diet that boost the immune system and protect against environmental toxins, as well as flush them from the body, is essential. Also, start reading the labels of all the foods you buy - preferably before you buy them. Highly processed foods with chemicals and preservatives are common in causing "allergic" reactions. Become aware of what each ingredient is and if you don't know (and can't find out) what something is avoid eating it. I am a certified herbal consultant so feel free to contact me with any questions regarding specific herbs I would recommend.
