Treats phlegm-fluid retention (Tan Yin) lingering in the epigastrium. The arm is painful and difficult to lift; the hands and feet cannot move freely.
Zhi Mi Fu Ling Wan (Poria Pill for Guiding Confusion) is most appropriate. Feng Hua Mang Xiao (Desiccated Mirabilite) should be viewed separately. Ban Xia (Pinelliae Rhizoma), Zhi Ke (Aurantii Fructus), Fu Ling (Poria), and Gan Cao (Glycyrrhizae Radix et Rhizoma) combine into four ingredients. For retained phlegm and fluid, its efficacy surpasses miraculous elixirs. (Processed Ban Xia 2 liang, Fu Ling 1.5 liang, Zhi Ke 0.7 qian, Desiccated Mirabilite 0.5 qian.)
Ke Yunbo stated: The root of phlegm and fluid lies in water metabolism. Water enters the Stomach, overflows with essence and qi, and is transported upward to the Spleen; this is a process from Yang entering Yin. The Spleen disperses essence, which returns upward to the Lung; this is Earth Qi ascending. It regulates water passages, transporting downward to the Bladder; this is Heaven Qi descending. Water essence distributes in all directions, traversing the Five Meridians; this is water entering the meridians to transform into blood. If Yin and Yang are disharmonious, clear and turbid energies interfere with each other, Stomach Qi becomes chaotic in the middle, Spleen Qi fails to ascend clearly, and Lung Qi stagnates in its descent; thus, phlegm and fluid arise. Phlegm and fluid share the same origin but differ in Yin and Yang nature. When Yang is excess and Yin is deficiency, water energy condenses to form phlegm; when Yin is excess and Yang is deficiency, water energy overflows to form fluid. To eliminate phlegm, descending Qi and clearing Fire treats the branch (symptom), while tonifying Yin and promoting urination treats the root (cause). To scour fluid, descending Qi and drying Dampness treats the branch, while warming the Kidney and promoting urination treats the root. This formula seeks to combine both approaches for comprehensive treatment. Ban Xia dries Dampness, Fu Ling leaches out Dampness, Desiccated Mirabilite softens hardness, and Zhi Ke promotes Qi movement. It differs from Er Chen Tang's sweet and緩 (gentle/slow) nature, and stays far from the harsh and fierce action of Meng Shi Tan Wan (Nostoc Pill). It is likely a moderate agent among purgatives.
○ Astringents can consolidate leakage
For sweating due to blazing fire, use Dang Gui Liu Huang Tang. (Sweating while awake is called spontaneous sweating; sweating while asleep is called night sweating.) Di Huang (Rehmanniae Radix), Huang Qin (Scutellariae Radix), Huang Lian (Coptidis Rhizoma), Huang Bai (Phellodendri Cortex), and Dang Gui (Angelicae Sinensis Radix). (Raw Rehmannia Root, Prepared Rehmannia Root, Phellodendron Bark, Scutellaria Root, Coptis Rhizome, Angelica Sinensis Root in equal parts; Astragalus Root doubled.) Doubling the use of Huang Qi (Astragali Radix) favors moving outward to the exterior. The subtle application of bitter and cold properties lies in consolidating floating Yang.
Chen Xiuyuan said: Sweating caused by Yin deficiency and Fire disturbance benefits from the Yin-nourishing effects of Dang Gui, Shu Di Huang (Prepared Rehmanniae Radix), and Sheng Di Huang (Raw Rehmanniae Radix), as well as the Fire-clearing effects of Huang Qin and Huang Lian; this addresses the root of sweating. However, the subtlety of this formula lies in its bitter-cold nature. Cold overcomes heat, and bitterness can strengthen/consolidate. One might fear that excessive bitter-coldness damages Middle Jiao Qi. The Middle is the guardian of Yin. The more deficient the Yin, the more active the Fire; the more active the Fire, the more profuse the sweating. The particular brilliance lies in adding double the amount of Huang Qi amidst the great bitter and cold herbs. This allows Huang Qi to lead the bitter-cold properties entirely to the exterior, to solidify the sweat pores, preventing the medicinal nature from lingering in the interior and causing harm. This principle is very subtle; commentators have often misunderstood it. I hereby highlight and clarify it.
