DERMA-IONX is helpful for allergies. It is an oral homeopathic product which stimulates the enzyme systems in the body and helps with assimilation of nutritional components in diet and supplements. I would give a half dose of DERMA-IONX on the breakfast and supper food. After there are signs of improvement you can give a whole dose once a day. I would also give Probiotics. In order to improve allergies one usually needs to restore the gut flora. OMEGA 3,6,9 would also be helpful to decrease inflammation in the gut and reduce allergy symptoms.
I would also suggest that you give only filtered water for drinking if your water contains chlorine or fluoride. What kind of food are you feeding?
