When a person suffers from wind-stroke with hemiplegia (stroke with paralysis on one side of the body), their pulse is rapid, their complexion is dry and dark/blackish, their hands and feet are immobile, and their speech is slurred. How should it be treated? If the pathogen is located in the upper part, use emesis (inducing vomiting); if in the middle, use purgation; if in the lower part, use tonification; if in the exterior, use diaphoresis (sweating method); if in the interior, use warming, pressing, and hot compresses. "Emesis" refers to expelling phlegm-saliva; "purgation" refers to unblocking obstructions; "tonification" refers to replenishing deficiencies; "diaphoresis" refers to inducing sweating; "warming" refers to dispelling dampness; "pressing" refers to dispersing qi stagnation; "hot compresses" refer to assisting yang qi. Treatment must be tailored to suitability; how can it be uniform? The key lies in seeking the root. If the pulse is floating, use diaphoresis; if slippery, use emesis; if deep and choppy, use purgation; if tight, use warming; if slow, use hot compresses; if closed/stagnant, use pressing. One must carefully examine whether these methods are applicable; thus, treatment cannot be uniform.
The "Wu Ding" (Five Types of Ding Sores) are all caused by excessive anger, joy, worry, or thought; exposure to cold or heat; indulgence in strong wine; overconsumption of sweet and fatty foods; eating poisonous fish; and excessive sexual activity. These factors accumulate toxic pathogens that infiltrate the zang-fu organs. If not dispersed for a long time, they transform into Ding sores. There are five types: first, Bai Ding (White Ding); second, Chi Ding (Red Ding); third, Huang Ding (Yellow Ding); fourth, Hei Ding (Black Ding); fifth, Qing Ding (Green/Blue Ding). Bai Ding arises below the right nostril. Initially, it resembles a millet grain, with a red root and white head. It may cause numbness or itching/pain, leading to aversion to cold and heavy head, resembling wind-cold syndrome (Taiyang disease), loss of appetite, chest and diaphragm fullness/distension. Death occurs if panting and dizziness/confusion appear; otherwise, it is treatable. This illness will inevitably bring disaster within five days; urgent treatment is required. Chi Ding appears under the tongue. Both root and head are red. Upon onset, pain occurs, the tongue base becomes stiff making speech impossible, frequent fright, irritability, mental confusion, excessive thirst with continuous drinking, and urinary obstruction occur. Death occurs if mania develops; otherwise, it is treatable. This illness will inevitably bring disaster within seven days and becomes incurable. Both adults and children can suffer from it. Huang Ding arises at the edge of the lips and gums. Its color is yellow, containing yellow fluid. Upon onset, it causes polyphagia followed by regurgitation, numbness of hands and feet, uncontrollable salivation, abdominal distension with irritability, hypersomnia. Death occurs if insomnia develops; otherwise, it is treatable. Hei Ding arises in front of the ear, resembling a scar, black in color, with variable length. It causes trismus (lockjaw), insensibility of the waist, spine, legs, and knees, or pain. Disaster will inevitably occur within three years, and it is incurable. This is due to the gradual exhaustion of Kidney Qi. Sexual activities should be strictly moderated. Qing Ding arises below the eyes. Initially resembling a tumor or scar, it is green/blue in color and hard as stone. It causes blurred vision, excessive fear, palpitations, startle, and restless sleep. If prolonged without resolution, it leads to blindness or essence depletion. Disaster will inevitably occur within one year. The root of Bai Ding is in the Lung; the root of Chi Ding is in the Heart; the root of Huang Ding is in the Spleen; the root of Hei Ding is in the Kidney; the root of Qing Ding is in the Liver. The manifestations of the Five Ding sores represent major diseases and must be carefully examined. The treatment methods are detailed below. (In Lu's edition, eight prescriptions follow here; printed editions lack them, so they are appended at the end of Volume II.)
