Medicine is the science about human beings' struggle against diseases and improvement of health. Its object is the people of society. Therefore, medicine is closely related to social sciences and medical ethics. The renowned medical historian Sigurst of this century pointed out: "Medicine is a social science." Every action in medicine always involves two types of parties - doctors and patients, or more broadly, medical communities and society. Medicine is nothing more than a multi-faceted relationship between these two groups of people. Due to the development of medical science and the transformation of the medical model, people have shifted from the traditional biomedical model to the biological, psychological and social medical model.

Around the world, most countries and regions regard modern Western medicine as orthodox medicine, also known as conventional medicine, general medicine, current medicine, or mainstream medicine. Medicine other than Western medicine is called non-mainstream medicine, alternative medicine, complementary medicine, alternative medicine, unconventional medicine, etc.

Medicine is divided into two parts: one part is the foundation, which is the biological science; Another part of medicine is even more important and also the main body of medicine - clinical medicine. In the field of medicine, a new discipline has emerged in the past decade or so: evidence-based medicine. It is necessary to fully seek reliable clinical evidence, because the evidence we obtain from the laboratory alone is not sufficient to explain many issues.

Moreover, medicine itself is a part of science and inherently possesses certain humanistic characteristics. So, medicine is still a human science and still a way of life.
