There are six types of fluid retention (Yin). Suspended fluid (Xuan Yin), overflowing fluid (Yi Yin), and phlegm-fluid (Tan Yin) interlock and linger. Phlegm-fluid is merely one of the six types of fluid retention. When people suffer from this condition but it is only called "phlegm-fluid," it is because after long-term stagnation, it inevitably transforms into phlegm. This often occurs due to the blockage of the air passages and the obstruction of Jin-Ye (body fluids) circulation. It is like a ditch being blocked; when accumulated water stagnates, it flows backward and upward, accumulating turbid, foul-smelling substances without exception. If one does not dredge and open the ditch, but instead attempts to clarify and purify the already obstructed water to make it clear, such an approach is unreasonable.
Symptoms manifesting as wheezing, cough, vomiting, diarrhea, dizziness, vertigo, heart palpitations with restlessness (Xin Cao), panic attacks (Zheng Chong), fright palpitations (Jing Ji), alternating chills and fever, pain and swelling, chest fullness and diaphragmatic oppression (Pi Ge), or complete obstruction. Or there may be gurgling sounds in the chest and hypochondrium, or a sensation of cold water on the back. All these are caused by dietary factors. This is akin to water obstruction where turbid and foul substances accumulate. Therefore, those skilled in treating phlegm do not treat the phlegm directly but regulate Qi. When Qi flows smoothly, the body's Jin-Ye also flow smoothly along with it. One should use Su Zi Jiang Qi Tang (Perilla Fruit Descending Qi Decoction) and Dao Tan Tang (Phlegm-Draining Decoction), half a dose of each, decocted together. Alternatively, use Xiao Ban Xia Fu Ling Tang (Minor Pinellia and Poria Decoction) with Zhi Shi (Immature Bitter Orange) and Mu Xiang (Aucklandiae Radix), half a qian each, taken with Wu Tao Wan (Five-Pellet Pill). Or, prepare the ingredients of Wu Tao Wan according to their proportions as a herbal drink. This method is particularly good. In daily life, if there are no other issues, only a few mouthfuls of phlegm, either clear or hard, use Er Chen Tang (Two-Cured Decoction) or Xiao Ban Xia Fu Ling Tang. If there is much phlegm, take Qingzhou Bai Wan Zi (Qingzhou White Pills) intermittently, combined with Lai Fu Dan (Reviving Pill). If Bai Wan Zi is mixed with Ba Shen Lai Fu Dan (Eight-God Reviving Pill), it is named Qing Shen Wan. This is not only for treating phlegm-fluid but is especially effective for wheezing, cough, vomiting, retching, and food regurgitation (Fan Wei). If medication is ineffective, use Er Sheng Tang (Two-Life Decoction) with half a qian of Mu Xiang. If stubborn phlegm-fluid rises with rebellious Qi and resists pharmacological resolution, it should be purged from the lower jiao. Use Wu Ge Kuan Zhong San (Five Diaphragms Midst-Widening Powder) with half a qian of Ban Xia, taken with Po Yin Wan (Fluid-Breaking Pill). Assist with Ban Shu Wan (Half-Sulfur Pill), lest constipation recur and fluid retention remain uneliminated. Ban Shu Wan should be taken regularly. If stool passes spontaneously without medication, or in the case of the elderly and debilitated individuals, promote urination. Use Xiao Ban Xia Fu Ling Tang, substituting Chi Fu Ling (Red Poria) and doubling the dosage. Or use Dao Tan Tang with half a qian of Zhu Ling (Polyporus).
For dizziness and vertigo caused by phlegm-fluid, or cases developing into Yin-Jue (Cold-Faintness due to Fluid Retention), add Mu Xiang to Er Sheng Tang and swallow Qingzhou Bai Wan Zi and Ling Sha Dan (Cinnabar Pill), named Qing Ling Dan. Or swallow Yang Zheng Dan (Upright-Qi Pill) or Ban Shu Wan. When phlegm-fluid enters the four limbs, causing soreness and pain in the shoulders and back, and softness and numbness in both hands, physicians may mistakenly diagnose it as Wind pathogen, which is incorrect treatment. Use Dao Tan Tang with Mu Xiang and Jiang Huang (Curcuma Longa Rhizome), half a qian each.
When suffering from phlegm-fluid disease that generates various syndromes, one should not be constrained by these symptoms nor arbitrarily name them. Prioritize treating the fluid retention. Once the fluid retention dissipates, the various symptoms will heal themselves. There are cases of sudden faintness and confusion, deviation of the mouth and eyes, resembling Stroke (Zhong Feng) but actually not Stroke; trembling and dragging of the four limbs, feeling light as floating clouds, resembling Deficiency but actually not Deficiency. All these are caused by phlegm-fluid. Additionally, Kidney Deficiency Cold fails to control water, causing evil water to overflow upward, thus generating phlegm-fluid. Use Ba Wei Wan (Eight-Ingredient Pill).
