Is this trial a fit for you?

Likely a good fit

Adults (18–75) with primary fibromyalgia, certain traditional Chinese medicine patterns, and a baseline pain score of at least 4 who are not currently on FM therapies.

Probably not a fit

Patients with significant comorbidities, MRI contraindications, or who do not respond to herbal treatment may see limited or no benefit.

What this trial studies

This randomized, double-blind, placebo-controlled trial examines the safety and therapeutic potential of Yangyin Roujin Decoction in adults with fibromyalgia. The study collects serum, fecal samples, and brain MRI to explore possible mechanisms, including gut microbiota and neuroimaging changes, over 12 weeks. Participants are adults with fibromyalgia meeting ACR 2016 criteria, experiencing pain, and not currently on FM medications. Outcomes focus on pain reduction, physical function, and quality of life, alongside biomarker and imaging analyses. The trial is conducted at Guang'anmen Hospital in Beijing with lead sponsor Juan Jiao.

Why it matters

Potential benefit: If successful, participants may experience reduced pain and better daily functioning, with added insights into how the herbal formula works.

How similar studies have gone: Similar herbal approaches have shown signals of benefit in fibromyalgia in preliminary studies, but robust randomized data are limited; this design aims to provide more rigorous evidence.
