The way we treat allergies today, with Zyrtec and Claritin, is medieval medicine. It doesn't solve the underlying problem; it just tries to cover it up.
Allergy immunotherapy is the future. Most people don't realize that allergies are now a curable disease. In the future, taking Claritin for allergies is going to seem like taking Tylenol for an ear infection. Why would you treat the symptoms when you could just cure the disease?
I started Wyndly (https://www.wyndly.com) to bring immunotherapy for pollen, pets, and dust across the USA. But we'll expand into food allergies soon, too.
