The Use of Hydrogen Ion Water (Shan Shang Water) in the Treatment of Allergic Rhinitis

The goal of this clinical trial is to evaluate whether Shan Shang Water (hydrogen ion water) can help treat allergic rhinitis in adults and affect immune markers. Does Shan Shang Water reduce allergic rhinitis symptoms? What changes occur in immune markers when using Shan Shang Water? Researchers will compare Shan Shang Water to a placebo (an inactive substance) to see if it effectively treats allergic rhinitis. Participants will: Take Shan Shang Water or a placebo every day for 24 weeks. Visit the clinic every four weeks for checkups and tests. Record symptoms in a diary, noting things like sneezing, nasal congestion, and any use of medication.
