Alternative treatment strategies for neuropathic pain: Role of Indian medicinal plants and compounds of plant origin-A review

Neuropathic pain is a complex, chronic pain state accompanied by tissue injury and nerve damage. This important health issue constitutes a challenge for the modern medicine worldwide. The management of neuropathic pain remains a major clinical challenge, pertaining to an inadequate understanding of pathophysiological mechanisms of neuropathic pain. Various classes of drugs have been reported effective for the management of neuropathic pain viz. opiates, tricyclic antidepressants, and antiepileptic agents. However, association of adverse effects with these drugs hinders their confident prescription in people with neuropathic pain. Recently, various medicinal plants have been reported effective for the management of neuropathic pain. So, it may be prudent to look beyond synthetic drugs pertaining to their unprecedented pharmacotherapeutic effects with lesser adverse effects. The extensive literature review has been carried out from databases such as Science direct, Scifinder, Wiley online library, PubMed, Research gate, Google scholar and Chemical Abstracts. The list of Traditional Indian Medicinal plants (TIMPs) and isolated compounds have been compiled which have been reported effective as an alternative therapy for the management of neuropathic pain. This helps the researchers to discover some novel therapeutic agents against neuropathic pain.
