Cancer continues to represent a formidable global health challenge, underscoring the urgent need for the development of cost-effective therapeutic strategies. The design of nanomedicines with precise targeting capability and enhanced bioavailability opens new opportunities in cancer therapy. Among all the nanoplatforms, plant-derived nanoparticles have attracted more attention because of their excellent biodegradability, biocompatibility and low cytotoxicity. Bio-inspired nanocarriers use the abundance of phytochemical diversity present in medicinal plants to target multi-pathway signaling and counteract resistance mechanisms of cancer. The utilization of bioactive compounds from plants, including flavonoids, alkaloids, and polyphenols, leads to increased anti-cancer activity with fewer side effects. While these features are promising, there are several challenges to be overcome for successful clinical outcome (stability, large-scale production, controlled drug release, etc.). Herein, different innovations are discussed related to the plant-based nanomedicines, particularly in the context of sustainable and effective anti-cancer therapy. The ability of plant-based nanoparticles to modulate multiple cellular pathways represents a key advantage, as it can disrupt cancer progression and resistance mechanisms. What makes the Phytochemicals ideal candidate for targeted cancer therapies is that they naturally possess unique properties such as, antioxidant, anti-inflammatory and pro-apoptotic. Furthermore, Inhibition of tumor growth, suppress metastasis, and enhance immune responses which will contribute to comprehensive cancer control are achievable by the use of these plant-based bioactive compounds. Furthermore, the inherent biodegradability of plant-derived nanoparticles minimizes long-term toxicity concerns, aligning with the principles of sustainable medicine. Integrating nanotechnology with nature-originated therapeutic agents for producing plant-derived nanomedicines, show huge prospects in reshaping cancer treatment paradigms. This review highlights the confluence of phytochemicals and nanotechnology, focused on novel formulations that target precision and patient care in cancer.
