Phytotherapeutic Frontiers: A Comprehensive Review of Medicinal Plants as Adjuncts in COVID-19 Management

Unexpected findings emerge when nature encounters pandemic challenges. From mountain slopes, remedies arise shaped by harsh climates. Such conditions foster strong chemical defenses in plants. One such defense disrupts a key virus enzyme, similar to lab-made drugs. Instead of only attacking germs, these substances also calm body reactions gone awry. They can block the spike protein's interaction with human cells while reducing excessive immune signals associated with severe illness. Structural features within these compounds may explain why some are more effective than others. Tiny carriers developed through advanced methods help them reach target sites more effectively. Evidence has accumulated gradually across recent studies. Not every plant compound is equally successful, as effectiveness depends on precise molecular interactions and stability within the body. Delivery may be as important as the compound's origin or structure. Insights come not from individual experiments alone, but from patterns observed across multiple studies. Most importantly, different levels of evidence are distinguished here, ranging from lab experiments and computer forecasts to animal tests and limited human research, with the awareness that digital results often fail in real medical settings unless confirmed through rigorous testing. Rooted in traditional plant knowledge yet guided by modern methods, this study maps a path toward discovering natural remedies while maintaining a critical assessment of whether the reported health benefits are supported by sufficient evidence.
