That makes sense. And that's why some people are now interested in new approaches, such as using stem cells to regulate the immune response, rather than just blocking symptoms. The article https://ways2well.com/blog/ste....m-cell-treatment-for describes how stem cells can influence the mechanisms of allergic reactions and attempt to "reset" the immune system so that it does not respond so aggressively to allergens. Although research in this area is still ongoing and many aspects have not been conclusively proven, this may be an interesting prospect as an alternative or addition to conventional treatments. But before trying something like this, it is best to talk to your doctor or immunologist.
