Summary

This study tests a traditional Chinese medicine approach—Yiqi Wenyang Sanhan Formula taken orally plus acupoint application—for people with both allergic rhinitis (hay fever) and asthma during a quiet phase. The goal is to see if it can improve disease control and prevent flare-ups. 188 participants aged 16-79 will be randomly assigned to treatment or placebo in a double-blind design.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Yiqi Wenyang Sanhan Formula (Chinese herbal medicine) combined with acupoint application
What this could lead to
If successful, this could provide a new option to prevent flare-ups and improve quality of life for people with both allergic rhinitis and asthma.
What could go wrong
This is an early phase 1 trial, so safety and effectiveness are not yet proven. The herbal formula may not work better than placebo, and results may not apply to all patients.
