Immunotherapy is a natural allergy remedy. It’s a process that desensitizes your body to allergens by them to your body, via serum, in small doses. As treatment progresses, the amount of these allergens (also known as antigens) in the serum increases so your immune system learns to tolerate and then ignore them, making you a much happier person during allergy season!
There are two types of immunotherapy: shots and sublingual (under the tongue) drops. Both are effective.
