As for Phlegm (Tan), it is generated from damp earth and condensed fluids. When phlegm resides in the body, like flowing water, it must be smooth and unobstructed so that limbs and joints move freely, following the Qi's circulation. It may arise from contraction of Wind-Cold-Damp-Heat, or from injury by Seven Emotions or diet, causing Qi rebellion and fluid condensation into phlegm. It may remain knotted in the chest or stagnate in meridians, ascending and descending with Qi, reaching nowhere without causing harm. Danxi said: "Various diseases generate phlegm; Fire-Phlegm generates strange symptoms." If phlegm remains in the Zang-Fu organs, it manifests as Fluid retention (Yin), cough, distension, vomiting, vertigo, epilepsy, acid regurgitation, heartburn, palpitations; if stagnant in meridians, it manifests as pain, numbness, nodules, masses, chills and fever. These are all manifestations of pathogenic phlegm. Alas! Phlegm originates from the Spleen and Stomach; treatment should prioritize regulating the Spleen and Stomach and drying dampness. Generally speaking, Heat-Phlegm is cleared, Damp-Phlegm is dried, Wind-Phlegm is dispersed, Stagnant-Phlegm is opened, Stubborn-Phlegm is softened, Food-Phlegm is digested. There are also Five Types of Fluid Retention (Wu Yin): First, Xuan-Yin (Hanging Fluid), where drinking water flows to the hypochondrium, causing pain upon coughing and spitting; Second, Yi-Yin (Overflowing Fluid), where drinking water flows to the four limbs, failing to sweat when it should, causing body swelling and pain; Third, Zhi-Yin (Supporting Fluid), characterized by Qi rebellion requiring leaning to breathe, shortness of breath, difficulty lying flat, and a swollen appearance; Fourth, Tan-Yin (Phlegm-Fluid), where the person is constitutionally weak, with gurgling sounds in the intestines; Fifth, Liu-Yin (Retained Fluid), characterized by aversion to cold on the back, shortness of breath with thirst, pain in the four limbs and joints, pain in the hypochondrium radiating to the clavicle, and worsened coughing. These five types of fluid retention present differently. Alternatively, some suffer from Zhong-Tan (Central Phlegm), resembling wind syndrome, with flaccid paralysis of limbs, deviation of mouth and eyes, inability to speak, hemiplegia; or localized cramping pain in limbs or body, excessive sleepiness, drooling in the mouth. This is also a sign of phlegm. One must not mistakenly use Wind-dispelling drugs; such cases require careful consideration and administration.
