Kratom leaf extract alleviates anxiety and bladder dysfunction in stressed mice

Why it matters

This peer-reviewed study demonstrates that kratom leaf extract may help manage both anxiety and bladder pain in chronic stress conditions, opening new therapeutic avenues for patients with stress-induced bladder disorders.

The big picture

Interstitial cystitis and overactive bladder are debilitating conditions affecting millions. Previous research suggested kratom's active alkaloid mitragynine has analgesic and anxiolytic properties. This research validates those properties in a preclinical model of stress-induced bladder dysfunction.

Key findings

• Kratom leaf extract (2.5-5 mg/kg mitragynine equivalent) reversed stress-induced anxiety behaviors in male mice
• Treatment reduced bladder pain sensitivity measured by von Frey testing
• Kratom significantly decreased abnormal bladder contractions induced by muscarinic stimulation
• Mast cell infiltration in bladder tissue was reduced with kratom treatment
• Effects were comparable to solifenacin, a standard overactive bladder medication

What they say

Our results indicate that treatment with kratom leaf extract attenuated chronic stress–induced bladder pain responses, voiding abnormalities, and mast cell numbers, suggesting a potential modulatory effect on stress-induced bladder dysfunction. — Research team, Prince of Songkla University

Bottom line

Preclinical evidence suggests kratom may offer therapeutic benefits for stress-related bladder dysfunction and anxiety, warranting further human clinical trials.
