A composition for gene therapy or transfection includes nucleic acid, natural polyphenol, and cationic molecules. There are several phenolic hydroxyl groups in the natural polyphenol, so as to eliminate free radicals, prevent cancer, fight inflammation, and provide antioxidants feature. Compared with the delivery of cationic molecules alone, the composition can significantly improve the transfection efficiency by about 60-70%, reduce the dose of effective transfection of cationic molecules by about 20 times, thereby reducing the toxicity of transfection and showing better organism compatibility. The composition of the present invention does not introduce other chemical reagents, does not require synthesis, has high biosafety, and can efficiently and safely deliver a plurality of nucleic acid molecules into cells. The composition can be used as a highly effective and low-toxicity nucleic acid drug in the treatment of gene-related diseases, and has good medicinal value.
