Pathology

Excess Yin is a Full Yin state pattern. It creates Cold symptoms which are similar to these of Yang Deficiency, such as feeling of cold, cold limbs, profuse but clear urination, pain that gets worse by pressure but relieved by warmth. It is because Yin is cooling in nature and the excessive occurrence of Yin extinguish the Yang fires. 

The Cold here mainly refers to Wind-Cold and Damp-Cold. They can invade the Interior Organs directly such as the Stomach, Large and Small Intestines and Uterus. They can also invade the Exterior and cause painful obstruction syndrome like Wind, Cold or Dampness invading the Channels, joints and muscles

When Yin becomes in Excess, this can lead to Body Fluids accumulating in the body and form Dampness or Phlegm. They may built up throughout the body, giving a general appearance of swelling and heaviness, or they may collect in a particular area of the body. For example, if they are in the abdomen, nausea and vomiting appears. If in the Lungs, cough with copious clear mucus occurs. 

Then stagnated Dampness may also turn to Heat, and a general hypoactivity of Organ functions appears. 

Causes

External Wind-Cold or Damp-Cold: Yin Excess is caused by over-exposure to cold, windy or damp environments and climates. The Pathogenic Evils stagnate and obstructs inside body, so that Yang is unable to balance Yin. The stagnated Dampness can also turn to Heat.

Diet: It especially occurs with over consumption of cold or damp foods, such as salads, fruits, juices, raw foods, iced drinks and frozen items such as ice cream and frozen yogurt. Refined foods, flour products, and hot greasy foods such as fried red meats can also be the causes.
