That's a very reasonable question. The bottom line is that stem cell therapy is a real field of medicine that is being actively researched in the context of immune disorders and inflammation. For example, mesenchymal stem cells can influence the immune response and reduce allergic inflammation, which in theory could help with conditions such as allergic rhinitis. An article I saw at https://ways2well.com/blog/stem-cell-treatment-for-allergies-a-new-approach-to-relief describes these ideas in considerable detail, explaining that this is not just marketing, but a direction that is being studied by scientists as a new strategy for alleviating the symptoms of immune reactions. But it is important to understand that many of these approaches have not yet undergone large-scale testing in major clinical trials, so you should be cautious and consult your doctor before resorting to such treatment.
