All individuals are categorized into eight constitution. The eight constitution each consist of a different dynamic order between twelve organs. The eight different dynamic orders physically and mentally form eight distinct individualities which hence are the eight constitutions.

Eight Constitution Medicine is a type of immunotherapy and approaches to treat the cause of an illness through restoring the weakened or dissipating immune system by changing the overly-unbalanced state of organs into a suitably-unbalanced state.

It also encourages patients to follow constitutional regimens, depending on his or her constitution, in order to prevent and treat illness. For example, patients should consume foods that would stimulate weak organs, they should also consume foods that would suppress strong organs. Overtime, such diet will convert the body from an overly-unbalanced state of organs to a suitably-unbalanced state. 

Foods according to one’s own constitution will strengthen his or her natural healing power [immune system] which will protect him against all kinds of disease but food harmful to one’s constitution will weaken natural healing power and make him susceptible to disease.

A meat diet will cause this individual to sweat more frequently and fall asleep easily; which are signs of good health for a Hepatonia. Activities that cause sweating, such as sports and sauna, will help relax the naturally-excited liver and permit good health.

Frequent bowel movement and discomfort in the lower abdomen is common for Cholecystonias who consume seafood often because seafood further suppresses an already weak large intestine and stimulate naturally-excited gall bladder and liver, causing illness. 

Because of their strong pancreas and stomach, Pacreotonias have a hearty appetite and may have a hard time restraining their hunger. If they consume spicy foods, chicken, and apples, they will add heat to their strong pancreas, which will make controlling their appetite more difficult. 

Their strong and tense stomach often causes indigestion. Their digestive problems are often accompanied by chronic headache and pain throughout the body. 

Meat oriented diets and unnecessary medication will harm the weak liver even further and cause Pulmotonias to develop not only all kinds of illnesses but also negative and passive attitudes. Pulmotonias often feel weak after perspiring.

Consumtion of meat and medication will not only cause chronic fatigue, indigestion, kidney failure, lupus, but will cause various types of intractable muscle disease like multiple sclerosis, Parkinson’s disease, etc. Excessive perspiration may also cause Colononias to be easily fatigued.

They often have complaints about chronic constipation but it will never develop into a severe illness. When healthy, Renotonias will not sweat; however, they will frequently perspire when unhealthy. Consuming cold foods or drinks often causes digestive problems.

Consumtion of cold foods or drinks will further weaken the naturally weak stomach, causing diseases that are difficult to treat. Warm foods and beverages, light eating throughout the day, and infrequent perspiration will permit good health.
