Like we’ve already mentioned, sometimes our immune system turns against us and misidentifies a harmless substance as a threat. In allergies, harmless substances cause a strong immune response in the body which causes sneezing, blocked nose, red rashes, swollen tongue, and lips as well as wheezing.
Allergic reactions need to be rapidly subsided to clear out any danger. And anti-histamine medicines can quickly do that. However, while they can treat an allergic reaction, there is no treatment that can help us stop being allergic to something.
