Purpose of Review: Ricinus communis Linn. is a rapidly growing perennial herb (aka Eranda or castor plant) that has long been used to cure a range of ailments in traditional medicine. An extensive search on its ethnomedicinal, phytochemistry, and pharmacotherapeutic potential is completed by meticulously examining information retrieved from Web of Science, PubMed, SciFinder, Google Scholar, Embase, and Infrastructure databases. Recent Findings: The plant has yielded beneficial chemical compounds such as alkaloids, flavonoids, coumarins, terpenoids, sterols, and fatty acids. Several reports are available on the anti-inflammatory, antinociceptive, antiasthmatic, antifertility, antihistaminic, hepatoprotective, antimicrobial, free radical scavenging activities, antioxidant, and various other biological roles of the crude herb and its metabolites. This review comprehensively discusses the biopotential of R. communis in pain and inflammation, as evident from in vitro, in vivo, and clinical data, as well as safety and toxicity concerns, various market formulations, and drug-drug interactions. R. communis shows potent anti-inflammatory and analgesic activity possibly by NF-kB, Nrf2, RAF/ERK, Fas receptor, and caspase-mediate apoptosis and Wnt signalling pathways. Summary: R. communis is widely distributed globally and is rich in bioactive phytoconstituents with multifaceted therapeutic roles. It modulates numerous inflammatory and biochemical markers and highlights its potential in the management of nociception and inflammation. These findings could pave the way for the identification and developing more effective strategies to combat nociception and inflammatory disorders.
