Curcumin, the principal curcuminoid found in turmeric (Curcuma longa), has been investigated for its potential benefits in managing peripheral neuropathy, particularly due to its anti-inflammatory, antioxidant, and neuroprotective properties. Preclinical studies (animal and cell models) have shown that curcumin can reduce oxidative stress and inflammation in nerve tissues, both of which are key contributors to the development and progression of peripheral neuropathy, especially in diabetes and chemotherapy-induced models. Some studies suggest curcumin may help prevent or attenuate nerve damage, alleviate neuropathic pain, and improve nerve regeneration.

However, scientific validation in humans remains limited. Only a handful of small clinical trials have evaluated curcumin for peripheral neuropathy, with some reporting modest improvements in pain and sensory symptoms but often with methodological limitations such as small sample sizes, short duration, and lack of rigorous controls. Additionally, curcumin’s poor bioavailability is a known challenge, although newer formulations are being explored.

In summary, while there is promising preclinical evidence and some early clinical data suggesting curcumin may benefit people with peripheral neuropathy, robust, high-quality clinical trials are lacking. Thus, its use is supported more by emerging scientific evidence than by long-standing traditional use for this specific condition, and the overall strength of evidence is currently low to moderate.
