First seen Jun 26, 2026 · Last updated Jul 01, 2026 · Updated 2 times

Summary

This study tests whether an extra virgin olive oil and water mouthwash can remove more leftover asthma medication from the mouth than plain water. The medication residue can cause problems like thrush or sleep apnea. Twenty healthy adults and adults with asthma will rinse with different mixtures and have their rinse samples measured. The study lasts up to 3 weeks.

What this could lead to
