✵Theory of Yin-Yang: the theory of Yin Yang is an ancient Chinese philosophical concept of naive dialectics, expressing the law of the unity of opposites.
✵Yin and Yang: the two fundamental principles or properties in the universe, ever opposing and complementing each other, the ceaseless motion of which gives rise to all the changes in the world- an ancient philosophical concept used in in traditional Chinese medicine for indicating various antitheses in anatomy, physiology, pathology, diagnosis and treatment, and for explaining the health and disease processes.
✵Yin: the female or negative principle, the structural or material aspect of an effective position.
✵Yang: the male or positive principle, the active or functional aspect of an effective position.

The resultant yang and yin are called yang within yin and yin within yin respectively.e.g., the night is regarded as yin in relation to the day, the period from nightfall to midnight is said to be yang within yin, and the period of the small hours is said to be yin within yin.
✵Yang within yang and yin within yang: Yang may be further divided into yang and yin.

✵Intercourse of Yin and Yang: interaction and combination of Yin Qi and Yang Qi, by which things, living and non-living, are thus produced.
✵Interdependence of Yin and Yang: the existence of one being the prerequisite for the existence of the other. Without "brightness"(yang), there would be no "darkness"(yin); without "interior"(yin), there would be no "exterior"(yang).

✵Waxing and Waning of Yin and Yang: of the two opposites of a single entity, increase of the one is usually associated with decrease of the other, e.g., functional activities(Yang) consume nutrient substances(Yin)-waning of Yin with waxing of Yang. Formation and storage of nutrient substance consume functional energy-waxing of Yin with the waning of Yang.
✵Balance between Yin and Yang: also known as Yin-Yang balance, a harmonious state of Yin and Yang by which health is guaranteed.

Theory of Yin and Yang:the basics.
The Basics: The basics for the Theory of Yin and Yang are briefly as:
✵Yin-Yang is the law of nature, the principle of all things, the mother of all changes, and the root of life and death.
✵Heaven pertains to Yang, while Earth pertains to Yin; the sun pertains to Yang, while the moon pertains to Yin.
✵Water pertains to Yin, while fire pertains to Yang.
✵All things are initiated by Yin and Yang. Life is based on Yin and Yang.
✵Yang gives rise to activity, and Yin makes the configuration.
✵What exists outside pertains to Yang, and what exists inside pertains to Yin.
✵There is Yang in Yin, and there is Yin in Yang.
✵As the back of the body is Yang, the heart is Yang within Yang.
✵As the back of the body is Yang, the lung is Yin within Yang.
✵As the abdomen is Yin, the kidney is Yin within Yin.
✵As the abdomen is Yin, the liver is Yang within Yin.
✵As the abdomen is Yin, the spleen is extreme Yin within Yin.
✵Yin, existing in the interior, is the basis of Yang; Yang, existing in the exterior, is the activity of Yin.
✵Yang is rooted in Yin, and Yin is rooted in Yang.
✵If one keeps Yin even and Yang firm, one's spirit will be sound.
✵If one's Yin and Yang fail to communicate, his essential Qi will be exhausted.
✵Yin in its extreme gives rise to Yang, while Yang in its extreme gives rise to Yin, a mechanism of Yin-Yang transformation,e.g., severe loss of fluids(Yin) may show symptoms of Yang nature, such as feeling hot and restlessness, and intense heat may bring on cold symptoms such as chills and cold limbs.
✵Yin in excess makes Yang suffer, and Yang in excess makes Yin suffer, a mechanism of disease explained by Yin-Yang theory,e.g., excessive cold(Yin) impairs Yang Qi, and exuberant heat consumes body fluids(Yin).
✵Excess Yang causes heat, and excess Yin causes cold.
✵Yin and Yang can be counted from one to ten, and inferred from ten to one hundred, counted from one hundred to one thousand, and inferred from one thousand to ten thousand and even to infinity, but the principle of Yin-Yang is just one(i.e., the unity of opposites.)
✵One must carefully observe the positions of Yin and Yang, and apply treatment properly until they are balanced.
✵Yang is usually redundant, while Yin is ever deficient, a theory advocated by Zhu Danxi, according to which the method of replenishing Yin is recommended as a basic principle for treating diseases.
