bubble_chart Pattern Analysis

1. Kidney Yang Deficiency with Water Flooding︰Excessive thick saliva, dizziness with blurred vision, palpitations, shortness of breath especially upon exertion, and in severe cases, throbbing below the navel. The tongue appears pale with a white, slippery coating, and the pulse is wiry and slippery. Due to congenital insufficiency and constitutional weakness, compounded by prolonged illness and lack of proper care, kidney yang becomes depleted. The kidneys govern water, and their fluid manifestation is saliva. When yang deficiency fails in its warming and transforming functions, saliva rises and is expelled. Key diagnostic points include palpitations and shortness of breath upon exertion, dizziness with blurred vision, and throbbing below the navel. The condition involves middle energizer deficiency-cold of the spleen and stomach, characterized by epigastric and abdominal stuffiness and fullness, limb fatigue, loose stools, poor digestion, shortness of breath, reluctance to speak, and a sallow complexion. The former condition should be treated by warming yang, transforming qi, and draining water, using Dried Rehmannia Root Decoction.
2. Spleen and Stomach Yang Deficiency︰Excessive thick and sticky saliva, epigastric stuffiness and distension, poor appetite, shortage of qi and reluctance to speak, fatigue and lack of strength, loose and thin stools, sallow and dull complexion, tongue texture swollen and pale with white greasy coating, and weak soggy pulse. Due to excessive consumption of raw or cold foods, overuse of cold or cooling medications, or prolonged illness leading to malnourishment, resulting in spleen yang deficiency. The spleen governs middle qi, and yang deficiency leads to weak qi, impairing transportation and transformation, and losing its ability to retain and control, thus causing upward reversal and excessive salivation. The two locations of disease are in the lower energizer and the middle region. Therefore, for diseases located in the lower energizer, the treatment should focus on warming the spleen and supporting qi, using the Middle-Regulating Decoction and modified Chebula Fruit Pill.

The condition of excessive salivation, in the kidney, is due to kidney yang deficiency, where qi transformation is impaired, leading to the upward overflow of water pathogens; in the spleen, it is due to middle transport deficiency, where qi fails to contain, causing the upward reversal of saliva. Both are primarily deficiency pattern.
