The global rise in cancer incidence has driven the search for safer, more effective therapies, with natural compounds gaining increasing attention. Phloridzin, a dihydrochalcone glycoside abundant in apple trees ( spp.), has demonstrated notable anticancer properties. This review summarizes its pharmacological profile, natural sources, and structural characteristics, with a focus on its mechanisms of antitumor action. We conducted a structured literature search across SCOPUS, PubMed, Google Scholar, and TRIP databases, highlighting studies on phloridzin's anti-proliferative, pro-apoptotic, anti-inflammatory, and metabolic regulatory effects across various in vitro and in vivo cancer models. Key mechanisms include glucose transporter inhibition (GLUT1/2), modulation of PI3K/AKT/mTOR and JAK2/STAT3 signaling, and suppression of metastasis and angiogenesis. Despite compelling preclinical evidence, phloridzin's clinical application is limited by low bioavailability. Novel delivery systems and synthetic derivatives, such as fatty acid esters, have shown improved pharmacokinetic profiles and efficacy. Future studies should prioritize translational research and clinical trials to validate phloridzin's potential as an adjunct or alternative therapy in oncology.
