Acupuncture may help relieve hay fever, according to new research published in the Annals of Internal Medicine. In the study, allergy sufferers who were randomly assigned to a dozen acupuncture sessions had more symptom relief and used less antihistamine medication than those who got a “sham treatment” or did not get the treatment. Experts don’t know for sure why acupuncture helps, but suspect that it “curbs inflammatory immune-system substances involved in allergic reactions,” according to HealthDay.
