Summary

This trial tests whether a new patch made from traditional Chinese herbs (CDAM) can reduce pain and improve function in people with plantar fasciitis, a common cause of heel pain. About 120 adults with heel pain lasting over six weeks will receive either the herbal patch or a standard ketoprofen patch. The study measures changes in foot pain, disability, and limitation using a validated questionnaire.

What this could mean

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

Active substance
A topical herbal patch (CDAM) containing Carthami Flos, Dipsaci Radix, Aconiti Lateralis Radix Praeparata, and Herba Menthae
What this could lead to
If effective, this patch could offer a natural, non-invasive option for relieving plantar fasciitis pain and improving foot function.
What could go wrong
The trial is relatively small and early, and results may not show a clear benefit over the standard patch. Herbal ingredients can also cause skin irritation or allergic reactions.
