Psilocybin could help repair chemotherapy-related peripheral nerve damage by promoting neurite growth, reducing inflammation, and easing neuropathic pain

Psilocybin is being investigated as a potential treatment for chemotherapy-induced peripheral neuropathy, a painful and often persistent form of nerve damage caused by cancer treatment. The central idea is that psilocybin may do more than alter mood - it may also support physical nerve repair through neuroplasticity, neurite growth, and anti-inflammatory effects. Chemotherapy-related neuropathy can leave patients with numbness, tingling, burning pain, and reduced mobility long after treatment ends, while current treatment options remain limited. Preclinical findings and emerging psychedelic research suggest psilocybin may encourage damaged neurons to regrow connections and may reduce the inflammatory signaling that worsens neuropathic pain. That possibility matters because a therapy that addresses both the subjective burden of chronic pain and the underlying biological injury could open a new direction for supportive cancer care. Evidence remains early, but the mechanism being discussed centers on nerve regeneration rather than symptom masking alone.
