All civilizations have protected human beings against diseases with specific medical methods since ancient times. Among these methods, the ones that were appropriate and problem- solving in the age in which they were born have survived up to present after being used for cen- turies. The developments in science and technology since the early 20th century allowed us to step towards modern medicine and caused medical practices used in the past to lose their popularity. However, modern practices in technology and drug industry have triggered a reorientation towards complementary medicine. This study presents an evaluation from the ethical perspective of the "Regulation on Traditional and Complementary Medical Practices", enforced after being published on the Official Gazette no. 29153 of October 27, 2014. The regulation sets the provisions related to methods of traditional and complementary medical practices for human health, education and au- thorization for people who are to put these methods into practice, and the principles and procedures for healthcare institutions where the methods will be used. The methods preferred by many peo- ple do not constitute an alternative to medicine. It should be emphasized that they are of comple- mentary nature. The regulation explains the quality of complementary practices which-contrary to common belief-are likely to have many side effects, and clarifies that the complementary medicine practices should be performed by physicians. This approach is directed relatedly to the principle of nonmaleficence in medical ethics. If traditional and complementary medical practices are per- formed by authorized physicians in healthcare centers meeting the requirements set in the regula- tion, it will be possible to avoid any maleficence for users of these methods.
