The Evolving Therapeutic Landscape of Gallic Acid: A Review of Mechanistic Insights and Clinical Potential. [PDF]
Mol Nutr Food ResABSTRACT Gallic acid (GA), a plant‐derived phenolic compound, is evolving from a general antioxidant into a specific molecular modulator and a functional building block for advanced biomedical materials. This review synthesizes recent insights underpinned by GA's “redox duality”—its capacity to act as either a radical scavenger or a pro‐oxidant.
