Most Allergies are due to pathogenic factors staying in body for very long time. Because of prolonged stimulation from pathogenic factors, body immune system gets confused. It does not know what to protect and what to attack. Then other autoimmune system problems may happen. Allergies are the reason or part of the reason for a lot of diseases of all over the body, for example migraine, hypothyroidism or Hashimoto’s disease, fibromyalgia, digestive issues like constipation and bloating, both male and female infertility and even cancers. There are a lot of patients coming to my clinic with different complains but have common symptoms of allergy such as nasal congestion, runny nose, sneezing, itching eyes, headaches, etc. For those difficult diseases with no answer from Western medicine, our first solution is to get rid of pathogenic factors, relieve allergies, and get immune system back to normal.
