Probiotic Potential of Lactobacillus Species in Allergic Rhinitis.

Since conventional allergy medication for asthma or allergic rhinitis (AR) can cause side effects which limit the patients' quality of life, it is of interest to find other forms of therapy. In particular, probiotic bacteria, such as Lactobacillus species, have shown anti-allergic effects in various mouse and human studies. For instance, administration of some Lactobacillus species resulted in nasal and ocular symptom relief and improvement of quality of life in children and adults suffering from rhinitis.
