Ancient herbal mix may shorten radiation mouth pain in cancer patients
NCT ID NCT07339774
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a traditional Chinese herbal oral solution and mouthwash to see if they can shorten the time head and neck cancer patients suffer from severe mouth sores caused by radiation therapy. About 128 adults aged 18-65 with non-metastatic head and neck cancers will receive either the herbal treatment or a placebo alongside their radiation. The goal is to reduce the duration of painful, severe mucositis (grade 3 or higher) and improve quality of life during treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Zishui Daohuo oral liquid and Kujiu mouthwash (Chinese herbal compound)
- What this could lead to
- If it works, this could provide a natural option to reduce the time patients suffer from severe mouth sores during radiation therapy.
- What could go wrong
- This is a small, early-phase trial with only 128 participants, so results may not apply to everyone. Herbal remedies can also cause allergic reactions or interact with other treatments.
