Chinese herbal medicine is the oldest form of internal medicine, and is
a branch of what is called oriental medicine or traditional Chinese
medicine.
The philosophy of Chinese herbal medicine is that the patient is viewed as a
whole, not a disease in isolation, or as a collection of symptoms. The
idea is that illness is due to an imbalance; health is a process, not a
destination.
All of nature is composed of two dualities: yin and yang;
light and dark; cold and hot, soft and hard and so on. There are
five elemental energies or substances within the body that are critical
for life: Jing (essence), Shen (spirit), Qi, Blood, and
JinYe (light/heavy).
Briefly, four types of Qi imbalances, and three Blood imbalances can
cause illness: deficient qu, sinking qi, stagnant qi, and rebellious
qi. Likewise deficient blood, stagnant blood, heat in the blood.
Conditions are classified as yin or yang; as imbalances of qi/blood; of
the jin ye fluids or with deficient or excess jing or shen. By
applying physical diagnosis with history taking, a remedy can be
recommended. For example, herbs that tonify (strengthen) Qi are ginseng,
citrus peel, astragalus etc.
