Rating (out of 5): 2

Lion’s mane mushroom (Hericium erinaceus) has attracted interest for its potential neuroprotective and neuroregenerative properties. In the context of peripheral neuropathy, the scientific evidence is preliminary but promising. Several animal studies have demonstrated that compounds found in lion’s mane, such as hericenones and erinacines, can stimulate nerve growth factor (NGF) synthesis and enhance nerve regeneration. For example, research published in the journal International Journal of Medicinal Mushrooms (2015) showed that lion’s mane extract promoted the regeneration of injured peripheral nerves in rats, leading to improved functional recovery. Additional studies have found similar effects, with increased neurite outgrowth and reduced neuropathic pain behaviors in animal models.

Human data, however, are limited. A few small clinical trials have explored lion’s mane for cognitive impairment, but its direct effects on peripheral neuropathy in humans remain largely unstudied. Anecdotal reports and traditional use in East Asian medicine suggest benefits for nerve health, but these are not robustly documented or specific to peripheral neuropathy.

In summary, while lion’s mane shows neurotrophic and neuroprotective effects in preclinical studies relevant to peripheral neuropathy, high-quality clinical trials in humans are lacking. Therefore, the evidence is rated as 2 out of 5, indicating low to moderate support based on current animal research, with more rigorous human studies needed to confirm efficacy.
