[Commentary] Zhang Zihe was one of the four renowned physicians during the Jin and Yuan dynasties in China and once served as an imperial physician. Needle ore and wax have been used for hair dyeing as early as the Tang dynasty. Modern science has proven that when iron reacts with vinegar, black ferric acetate is produced. Buckwheat flour, as recorded in Compendium of Materia Medica, can “dye hair black.” The combined use of these three substances can turn white hair black.
