Summary

This Phase 2 trial tests whether inhaling L-menthol before exercise can reduce breathlessness and improve exercise capacity in 20 adults with asthma. Participants will receive L-menthol or a strawberry-scented placebo in random order, then cycle to measure their breathing and discomfort. The study aims to see if this simple intervention offers relief during physical activity.

What this could mean

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

Active substance
L-menthol
What this could lead to
If it works, this could point toward a simple, non-drug way to ease breathlessness during exercise for people with asthma.
What could go wrong
This is a very small early-phase trial with only 20 participants, so results may not apply widely. The effect may be small or no better than placebo.
