Gongjin-dan (GJD), an herbal drug commonly used in Korea and China, is often used for the prevention and early treatment of amnesia. At the end of 2021, it was confirmed for the first time, using scientific research, that GJD, with its anti-aging mechanism, is able to protect and restore damaged brain nerve cells.
At present, modern medicine does not have a well-defined solution for the prevention and treatment of amnesia, while GJD, known in some Asian countries as the “Emperor’s Tonic,” is considered by Korean doctors to be an effective medicine in this field.
