Roughly, most of all clinically approved cancer chemotherapeutics have direct or structural analogy, their origin in natural products, thus underlining the continued importance of botanical pharmacology. In this vast field, the species Opuntia ficus-indica or nopal cactus deserves particular interest, as it is one of the few edible plant species with millennia-long exposure to human diets, a chemically diverse secondary metabolome, and adaptability to environments where conventional food crops do not survive. As an adapted species to extreme conditions of arid climates, Opuntia ficus-indica possesses crassulacean acid metabolism, water storage tissue with mucilage, and a multilayer defense system to cope with long-term drought. The same biochemical pathways responsible for these survival adaptations also underlie the species’ pharmacologically interesting secondary metabolites, including flavonoids, phenolic acids, nitrogen-containing betalains, sterols, polyunsaturated fatty acids, vitamins, and high-molecular-weight mucilage polysaccharides, each with unique biological activities, which have increasingly captured the interest of experimental investigations. Scientific interest in this plant has expanded considerably since the early 2000s. Studies now report anticancer activity, anti-inflammatory responses, neuroprotection, antimicrobial effects, and metabolic benefits, all from different fractions, different plant organs, and often different species of Opuntia. However, it is harder to find work specifically addressing the oral cavity. And that is the central puzzle this review is concerned about. OSCC kills approximately. 145,000 people annually, the oral mucosa is the first tissue any ingested phytochemicals reach. Yet the published literature barely asks what happens at that interface. Despite O. ficus-indica’s direct mucosal contact during ingestion and despite oral squamous cell carcinoma ranking among the ten most common cancers worldwide, the oral cavity has attracted minimal attention as a site of investigation among researchers. This disconnect is the central concern motivating the present review. Three aims structure the analysis that follows: a critical synthesis of the phytochemical diversity documented for O. ficus-indica; an appraisal of the mechanistic and in-vivo anticancer evidence, including an honest accounting of its limitations; and the construction of a translational argument for purpose-designed investigation of chemopreventive activity in OSCC models.
