Probiotics are also used to prevent and treat allergic rhinitis.
There’s a consistent improvement in the symptoms patients report after being treated with probiotics. Their quality of life improves because allergic rhinitis is a respiratory allergic reaction that usually triggers during spring and features symptoms such as repeatedly sneezing, especially during the morning, nasal congestion, rhinorrhea, nasal itching, and it is sometimes accompanied by asthma episodes.
Can Probiotics cure Hayfever?
After evaluating the performance of many different clinical trials, the probiotic strains commonly found to improve allergic rhinitis are Bifidobacterium longum, Lactobacillus acidophilus, Bacillus clausii, and Lactobacillus rhamnosus. They seem to be the best probiotic for allergic rhinitis, but since there is variation between one study and the other, some authors may seem to contradict each other and say that Lactobacillus acidophilus and Lactobacillus rhamnosus are not an effective treatment. There are excellent anti-histamine probiotics discussed here.
There is still much to research and find out about probiotics and allergy, and since there is not enough evidence yet, there are no current guideline doctors can use. However, since the late 90’s more and more research is showing up the effect of probiotics on the correct function of the immune system. Probiotics can be a safe addition to any program destined to prevent or control food allergy or allergic rhinitis, along with delivering extra health benefits to our gastrointestinal system. Curing food allergies can be complex.
