水二杯，先煮麻黄至一杯半，去沫，入诸药煎七分温服，日作三服。此即麻黄附子甘草
汤，分两略异。即以温经散寒之法，变为温经利水之妙。
汗出沾衣而色黄也。汗出入水，水邪伤心；或汗出当风所致。汗与水皆属水气，因其入

The latent nature of water qi. When the pulse is slow, it is because water belongs to Yin. The external manifestation of spontaneous panting occurs when Yin cold is excessive in the lower part and fails to harmonize with the Yang Qi in the chest; water qi obstructs Yang, leading to panting. Regarding symptoms such as eyelids swollen like a silkworm lying down and swelling of both calves, although not explicitly detailed in *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet), these signs are invariably present together.
My commentary: Although *Jin Gui Yao Lue* does not provide a specific formula for Zheng Shui (True Water Edema), the outline states: "Pulse is deep and slow, external symptom is spontaneous panting." Therefore, Zhen Wu Tang (True Warrior Decoction) and Xiao Qing Long Tang (Minor Blue Dragon Decoction) are direct and appropriate formulas for treatment. Yue Bi Jia Fu Zi Tang (Yue Bi Decoction plus Aconite) and Ma Huang Fu Zi Tang (Ephedra and Aconite Decoction) are comprehensive formulas for managing variant conditions. Gui Zhi Gan Cao Ma Huang Xi Xin Fu Zi Tang (Cinnamon Twig, Licorice, Ephedra, Asarum, and Aconite Decoction) added with five qian of Sheng Sang Bai Pi (Bark of Mulberry Root) and one liang of Hei Dou (Black Soybean) constitutes an ingenious prescription for extreme cases. This represents the proposed treatment method for Zheng Shui.
Shi Shui (Stone Water) refers to water accumulation in the lower jiao that is hard as stone. The pulse is naturally deep. External symptoms include fullness in the lower abdomen but no panting.
Ma Huang Fu Zi Tang (Ephedra and Aconite Decoction)
Ma Huang (Herba Ephedrae) (3 qian)
Zhi Gan Cao (Radix Glycyrrhizae Preparata) (2 qian)
Fu Zi (Radix Aconiti Lateralis Preparata) (1 qian)
Use two cups of water. First, boil Ma Huang until reduced to one and a half cups, skim off the foam, then add the other herbs and decoct until seven parts remain. Take warm. Divide into three doses per day. This is essentially the same as Ma Huang Fu Zi Gan Cao Tang (Ephedra, Aconite, and Licorice Decoction), with slight variations in dosage. It transforms the method of warming meridians and dispersing cold into the subtle art of warming meridians and promoting diuresis.
Huang Han (Yellow Sweat) refers to sweat that stains clothes yellow. It is caused by entering water while sweating, allowing water pathogenic factors to damage the Heart; or by exposure to wind while sweating. Both sweat and water belong to water qi. Because water enters and binds internally, it generates stagnant heat, resulting in yellow coloration. The pulse is deep and slow. External symptoms include feverish sensation of the body, swelling of the limbs, head, and face. If prolonged without cure, it will inevitably lead to carbuncles and pus.
For Huang Han, use Gui Zhi Shao Yao Ku Jiu Tang (Cinnamon Twig, Peony, and Vinegar Decoction) from *Jin Gui Yao Lue*. It treats body swelling, fever, sweating, and thirst, resembling Feng Shui (Wind Water Edema). The sweat stains clothes yellow like cypress juice, and the pulse is deep (whereas the pulse for Feng Shui is floating). This condition arises from bathing in water while sweating, allowing water to enter through the pores. (Water qi enters through the pores and damages the Heart, causing water and fire to invade each other, resulting in yellow color; water qi knots together, causing a deep pulse. One should read texts flexibly; this condition can also result from sweating after drinking alcohol and being exposed to wind. Even without external water, the sweat expelled may return inward due to wind, effectively becoming water. Furthermore, when the Spleen and Stomach are affected by dampness, long-standing dampness generates heat; the steaming interaction of damp-heat produces yellow color and sweating. From this, one can comprehend the meaning of "entering water"!)
Huang Qi (Radix Astragali) (5 qian)
Shao Yao (Radix Paeoniae Alba)
Gui Zhi (Ramulus Cinnamomi) (each 3 qian)
Ku Jiu (Vinegar) one and a half cups, water one cup. Decoct until eight parts remain. Take warm. The patient will likely experience mental restlessness (xin fan); resolution occurs after six to seven days. (Sweat originates from the Heart; Ku Jiu stops it too abruptly, causing mental restlessness. After six to seven days, righteous Qi recovers, and pathogens retreat spontaneously.)
Gui Zhi Jia Huang Qi Tang (Cinnamon Twig Decoction plus Astragalus) from *Jin Gui Yao Lue*. Patients with Huang Han disease have naturally cold lower legs and night sweats. After sweating, fever may persist; if prolonged, the skin becomes rough and scaly (jia cuo). Persistent fever leads to malignant sores. If the body feels heavy but lightens after sweating, prolonged illness may cause body numbness (rou bi) and even chest pain. Another presentation includes sweating above the waist but none below, with flaccid pain in the lower back and a sensation of something trapped in the skin. Severe cases involve inability to eat, body ache and heaviness, irritability, and difficult urination (above are all variant syndromes of Huang Han; the Master provided treatments to establish principles. Due to space constraints, only key points are recorded here). This defines Huang Han. (This statement indicates that although variants are numerous, their source always stems from water qi damaging the Heart. This summary shows that treatment methods adhere to the fundamental principle.)
Gui Zhi (Ramulus Cinnamomi)
Shao Yao (Radix Paeoniae Alba)
Sheng Jiang (Rhizoma Zingiberis Recens) (each 3 qian)
Zhi Gan Cao (Radix Glycyrrhizae Preparata)
Huang Qi (Radix Astragali) (each 2 qian)
Da Zao (Fructus Jujubae) (4 pieces)
Use three cups of water. Decoct until eight parts remain. Take warm. Shortly after, drink more than one cup of hot congee to assist the medicinal power. Cover with blankets to induce mild sweating. If sweating does not occur, administer again. The previous formula stops sweating, which is the standard treatment for typical Huang Han. This formula induces mild sweating, which is the treatment method for variant syndromes of Huang Han.
