Excess Yin is a Full Yin state pattern. Its symptoms are like those of the Cold and Damp Heat Pernicious Influences. When Yin becomes in Excess, this leads to Body Fluids accumulating in the body. 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 mucus occurs. Yin Excess often creates Cold symptoms which are similar to these of Yang Deficiency. It is because Yin is cooling in nature and the excessive occurrence of Yin extinguish the Yang fires. 

Yin Excess is caused by over-exposure to Cold or Hot Damp environments and climates. Pathogenic Cold stagnates and obstructs inside body, so that Yang is unable to balance Yin. Then stagnated Dampness turns to Heat, and a general hypoactivity of Organ functions appears. It especially occurs with overeating cold, 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.

Diagnosing a pattern in Chinese Medicine is no easy feat and should be left to professional practitioners.

In particular one has to know how to differentiate between different types of pulses and tongue coatings, shapes and colors. Here patients with Yin Excess will tend to exhibit slippery (Hua), tight (Jin), wiry (Xian) or full (Shi) pulses as well as a pale tongue with thick white coating.

Practitioners also learn to read from a long list of seemingly unrelated symptoms. Here patients with Yin Excess might experience symptoms like dampness, loose stools, frequent urination and abdominal distention and fullness (full list here above).
