Huandao Conditioning Application for Allergic Rhinitis Treatment

The goal of this clinical trial is to learn if the Huandao Conditioning Application works to treat allergic rhinitis in adults. It will also learn about the safety of this application. The main questions it aims to answer are:

Does the Huandao Conditioning Application improve allergic rhinitis symptoms as measured by the Rhinitis Control Assessment Test (RCAT) and nasal airway resistance tests? What medical problems do participants have when using the Huandao Conditioning Application?

Researchers will compare the therapeutic version of the application to a placebo version (a look-alike application that contains no therapeutic effect) to see if the Huandao Conditioning Application works to treat allergic rhinitis.

Participants will:

Use either the therapeutic or placebo version of the application daily for 1 week in Phase 1 Take a 2-week break with no application use Use the opposite version of the application daily for 1 week in Phase 2 Visit the clinic at the beginning and end of each phase for checkups and tests Complete symptom assessment questionnaires before each application use and 1-2 hours after use Be monitored for any adverse reactions throughout the study period
