For example there was a report by Tianjin First Central Hospital about the result of treating 19 cases of color blindness, among whom, 6 cases cured, 2 cases markedly improved, and 5 cases mild improvement. Another report dealt with the good result was written by Shanxi Chinese Traditional Medical College.
