The phenomenon of pain is complex in nature and multimodal, being a significant contributory factor affecting human health, quality of life, and psychological well-being. Pain can generally be categorized under three types that are nociceptive, neuropathic, and inflammatory pains, each arising from different specific mechanisms and etiologies, and thus effectively managed through this understanding, into various therapeutic procedures, such as pharmacological drugs, physical interventions, and psychologically oriented treatments. There is growing interest in natural alternatives to conventional pain therapies, especially phytochemicals, because of their potential efficacy and fewer side effects. Phytochemical constituent of clove, ginger, and turmeric have been traditionally used for their analgesic and anti-inflammatory effects, and in recent times, they find more usage in the marketed preparations claiming natural pain relief. These compounds thus offer a high level of therapeutic benefits as they alter and reduce the inflammation induced by pain pathways through several biochemical mechanisms. Another plant extensively sought and presently attracting much attention for its medicinal properties is Tectona grandis or teak. It contains bioactive compounds, particularly tectoquinone, which has shown promising analgesic and anti-inflammatory effects. Tectoquinone works through the following mechanisms, including inhibition of pain receptors and reduction of inflammatory mediators; therefore, it has the potential as a candidate in future therapies of pain. The growing interest in tectoquinone has led to the development of some commercial products that incorporate this compound in the form of relief against pain. These products, however, give more evidence on the market demands of natural solutions in pain management. In fact, current researches, patents, and associated studies emphasize that the scope of tectoquinone remains to be one of the key additions in the pharmacotherapeutic agent meant for application against pain. With that, it's on this realization that this review unites the varieties of types of pain, forms of mechanisms happening, discussion over the applicability of phytochemicals on the treatment, and a general review of Tectona grandis and one of its extracts known as tectoquinone.
