Le Huu Trac, whose nickname is Hai Thuong Lan Ong, is regarded as the ancestor of Vietnamese medicine. He passed on to the later generations many significant medical works with valuable remedies and wise words on medical ethics. His research on medical ethics has played a significant role in enhancing medical ethics for physicians today. The author follows a method of analysis, synthesis and comparison of data sources, in addition to using the logical method combining history, to study Le Huu Trac's medical ethics ideology through approaching the four principles of medical ethics. This is a general, popular and widely accepted approach in biomedical ethics research since the 1970s. The research result shows that the four medical ethics principles are expressed in Le Huu Trac's medical ethics ideology, in which the principles of beneficence and nonmaleficence tend to prevail over the principle of respect for autonomy.
