“Chronic pain lasting more than three months or persisting after normal healing is a significant global health issue. In a healthcare system, it is crucial to ensure proper chronic pain management. Traditional pharmacological and non-pharmacological pain management techniques may not fully meet the requirements of physicians regarding effectiveness and safety. Therefore, researchers are exploring natural analgesics.
Plant-based phytoconstituents show promise in relieving chronic pain associated with various diseases.
This study aims to review the latest advances in discovering natural bioactive compounds that can help alleviate chronic pain. It discusses the pathways of chronic pain and a multifactorial treatment strategy. It also organizes data on using plant- derived substances, such as cannabinoids, terpenoids, phenolics, and crude extracts. Additionally, it delves into the pharmacodynamics of cannabinoids, including their route of administration and elimination.
The review presents the results of 22 clinical trials on various cannabinoids for pain relief. It is important to note that opioids and other alkaloids from plants are not covered in this article due to their primary use in controlling acute rather than chronic pain.”
