Medicine includes theory and clinical practice; clinical practice includes diagnosis and treatment, and treatment includes medical treatment and health maintenance. The goal of medicine is to resolve disease and illness.

To clarify the theory of the origin of disease and illness, Yuan Shi Dian (YSD) medicine establishes disease, illness, and senescence as Effects; Tishang (bodily impairment - the malfunctioning of tissues and organs) and Heat Energy Deficiency as Causes; and Antui (press and rub), Heat Sources, appropriate exercise, adequate rest, and a good state of mind as Contributing Factors. In clinical practice, YSD medicine, through observation of Symptoms and Signs and using the aforementioned Contributing Factors, treats from the Cause to achieve the following: if there is disease and illness, life can be safeguarded, and disease and illness healed; if there is no disease and illness, aging can be countered, longevity increased, and disease and illness prevented. Observation of Symptoms and Signs is classified as diagnosis; Antui is classified as medical treatment, and the rest of the treatment methods are classified as health maintenance.
