Could a plant oil spray tame chronic sinusitis with fewer steroids?
NCT ID NCT07800273
First seen Sep 02, 2026 · Last updated Sep 03, 2026 · Updated 1 time
Summary
This trial tests whether adding a nasal spray made from pistacia lentiscus oil can help people with chronic rhinosinusitis control their symptoms while using a lower dose of a standard corticosteroid spray. Adults with the condition will be randomly assigned to either the oil spray plus a reduced steroid dose or the full steroid dose alone for 12 weeks. Researchers will measure changes in quality of life, nasal congestion, and runny nose to see if the oil spray works as well as the full steroid treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bactorinol nasal spray (pistacia lentiscus oil) plus a reduced dose of mometasone furoate nasal spray
- What this could lead to
- If it works, this could offer a way to control chronic rhinosinusitis symptoms with less corticosteroid use, potentially reducing side effects while keeping quality of life.
- What could go wrong
- This is a small, early-stage trial, so results may not apply broadly. The oil spray might not match the full-dose steroid in controlling symptoms, and nasal irritation or other side effects are possible.
