Allergies can be helped with acupuncture. In particular, there are points (2 in particular) that can reduce the responsitivity of the immune system to allergens. There are also points that can help with the symptoms of allergies(stuffy nose, fatigue, runny nose, etc.). We can also treat other complications of allergies such as sinus infections, bronchitis, etc. using both herbs and acupuncture. The herb formulas include herbs that are anti-viral and antibiotic.
Food allergies are either a true allergy or a problem with not digesting a food properly. This can be treated by using points that strengthening the digestion by increasing the production of stomach acid or digestive enzymes whichever is needed. Of course they can also be taken as supplements as well.
