One of the strengths of functional medicine is explore root causes of illness. In the case of allergy, allergen(s) trigger our immune system to overreact resulting in symptoms such as sneezing, itching, and runny nose. In severe cases, an emergency known as anaphylactic reaction is triggered resulting in shortness of breath and difficulty of breathing which require immediate medical attention.
Avoid allergens would be ideal, but not practical. Conventional medicine and integrative medicine can provide symptoms relief through use of anti-histamines, decongestants, and corticosteroid. There is also desensitization therapy in the form of allergy shots. While allergy shots are the most prevalent, there is another approach using allergy drops.
Allergy drop allows for desensitization - a process where dilute allergens in the form of allergy drops can over time teach one's body to ignore allergens instead of over reacting to them - this process is also known as sublingual immunotherapy.
Case History:
