Symptoms of food allergies include: fatigue, hives, eczema, abdominal pain, diarrhea, nausea, vomiting, nasal congestion, cough and asthma. Even more serious conditions include: difficulty breathing, decreased blood pressure, increased heart rate, dizziness, mental confusion, slurred speech, anxiety attack and cardiovascular collapse, according to the American Academy of Acupuncture and Oriental Medicine (AAAOM).
Many herbalists consider two major systems when dealing with allergies – the immune system and adrenal-stress handling system. These two systems are under great pressure due to environmental changes. The fast pace of modern living and working may have an adverse effect on these systems, as well.
