Borneol, a traditional Chinese medicine (TCM) with over a millennium history, has emerged as a promising alternative due to its multi-target mechanisms. This review synthesizes preclinical evidence demonstrating borneol’s dual analgesic pathways: (1) receptor-mediated actions (eg, TRPM8 activation, GABA agonism) and (2) immune modulation (eg, NF-κB suppression, ROS inhibition). Notably, comparative analysis with menthol reveals borneol’s superior TRPM8 specificity and lack of opioid-related side effects. By elucidating these mechanisms, we advocate for borneol’s integration into modern pain management strategies, highlighting its potential as a safe, multi-modal therapeutic.Keywords: Borneol, analgesia, TRPM8, immune modulation, neuropathic pain, Traditional Chinese Medicine
