Ancient Greek medicine was a compilation of theories and practices that were constantly expanding through new ideologies and trials. Many components were considered in ancient Greek medicine, intertwining the spiritual with the physical. Specifically, the theories and ideologies from which ancient Greek medicine derived included the humors, gender, geographic location, social class, diet, trauma, beliefs, and mindset. Early on, ancient Greeks believed that illnesses were "divine punishments" and that healing was a "gift from the Gods." As trials continued wherein theories were tested against symptoms and results, ancient Greek medicine also grew such that the pure spiritual beliefs as to “punishments” and “gifts” were converted to a foundation based in the physical, i.e., cause and effect.
Humorism (or the four humors) refers to blood, yellow bile, black bile and phlegm. It was also theorized that gender played a role in medicine because some diseases and treatments were different for women than for men. Moreover, geographic location and social class affected the living conditions of the people and might subject them to different environmental issues such as mosquitoes, rats, and availability of clean drinking water. Diet was thought to be an issue as well and might be affected by a lack of access to adequate nourishment. Trauma, such as that suffered by gladiators, from dog bites or other injuries, played a role in theories relating to understanding anatomy and infections. Additionally, there was significant focus on the beliefs and mind set of the patient in the diagnosis and treatment theories. It was recognized that the mind played a role in healing, or that it might also be the sole basis for the illness.
