治疗阳明病，脉象浮、发热，口渴想喝水，但小便不通利的情况；同时也治疗少阴病，腹泻持续六七天，出现咳嗽、呕吐、口渴、心烦、无法入睡的情况。
猪苓（去皮）、茯苓、泽泻、滑石（研碎）、阿胶（各一两）。用水四升，先煮前四味药，取药液二升，滤去药渣，加入阿胶使其溶化，每次温服七合，每日服用三次。
猪苓汤中含有两种茯苓（猪苓和茯苓），加上泽泻、阿胶和滑石研末。此方具有利水、滋阴兼清热的功效。（这就是五苓散去掉桂枝和白术，加入阿胶以滋阴。虽然五苓散也利水，但寒热性质截然不同，只有明辨者才知道。）能治愈小便闭塞、心烦、呕吐和口渴。（心烦是因为有热，小便不利属于湿，湿热郁结蒸腾，就会导致呕吐和口渴。）如果汗多导致胃中干燥，则不适合使用本方，恐怕会进一步耗伤津液，导致大便干结。（《伤寒论·阳明篇》说：“汗多胃燥……”）
茯苓、桂枝（各二两）、甘草（炙用一两）、生姜（三两）。用水四升，煮取药液二升，分次温服。
茯苓甘草汤由茯苓、桂枝、生姜组成，能泄除水饮（茯苓、生姜）并扶助阳气（桂枝、甘草），常用于治疗因水停心下引起的悸动和四肢厥冷之证。（水饮停滞在心下则引起悸动，阳气不能布达则导致四肢厥冷。出汗导致的厥冷并非此方所治，诸家对此认识不一，认为这是阳气不足之证，故使用茯苓甘草汤。）
茯苓（半斤）、桂枝（四两）、甘草（炙用二两）、大枣（十二枚）。用甘澜水一斗，先煮茯苓，减少二升水量后，再入其他药物同煮。
茯苓桂枝甘草大枣汤中，草和大枣培补脾胃之气，茯苓制约水邪，再加桂枝保护心阳。茯苓用量重且需先煮，（凡是在方剂中重用之药，通常需要先煮，以充分提取药效或缓和药性。）脐下悸动是水气上凌于心所致，桂枝能平冲降逆，对于悸动症状适宜使用。
Treats Yangming disease presenting with a floating pulse, fever, thirst with desire to drink water, and dysuria; also treats Shaoyin disease with diarrhea persisting for six or seven days, accompanied by cough, vomiting, thirst, irritability, and insomnia.
Zhu Ling Tang (Polyporus Decoction): Zhu Ling (Poria Cocos Sclerotium, peeled), Fu Ling (Poria Cocos Sclerotium), Ze Xie (Alisma Rhizome), Hua Shi (Talcum Powder, ground), E Jiao (Donkey-hide Gelatin) — each 1 liang. Use 4 sheng of water. First decoct the first four ingredients until reduced to 2 sheng, strain off the dregs, then add E Jiao and melt it. Take 7 ge warm, three times daily.
Zhu Ling Tang contains both types of Poria (Zhu Ling and Fu Ling), along with Ze Xie, E Jiao, and Hua Shi ground into powder. It promotes diuresis, nourishes Yin, and clears heat. (This is essentially Wu Ling San [Five-Ingredient Poria Decoction] without Gui Zhi [Cinnamon Twig] and Bai Zhu [Atractylodes Macrocephala Rhizome], but with added E Jiao to nourish Yin. Although both formulas promote diuresis, their thermal natures are distinctly different; only those with clear discernment understand this.) It cures urinary retention, irritability, vomiting, and thirst. (Irritability indicates Heat; dysuria indicates Dampness. When Damp-Heat stagnates and steams, it leads to vomiting and thirst.) If excessive sweating has caused dryness in the Stomach, this formula is contraindicated, as it may further deplete Body Fluids and lead to hard stools. (The *Shanghan Lun · Yangming Chapter* states: "Excessive sweating causes Stomach dryness...")
Treats Taiyang disease where, after sweating, the patient presents with cold extremities and palpitations below the heart, without thirst.
Fu Ling Gan Cao Tang (Poria and Licorice Decoction): Fu Ling (Poria Cocos Sclerotium), Gui Zhi (Cinnamomi Ramulus) — each 2 liang; Gan Cao (Glycyrrhizae Radix et Rhizoma, honey-fried) — 1 liang; Sheng Jiang (Zingiberis Rhizoma Recens) — 3 liang. Use 4 sheng of water, decoct to obtain 2 sheng, and take warm in divided doses.
Fu Ling Gan Cao Tang consists of Fu Ling, Gui Zhi, and Sheng Jiang. It drains Water-Fluid (via Fu Ling and Sheng Jiang) and supports Yang Qi (via Gui Zhi and Gan Cao). It is commonly used for palpitations and cold extremities caused by Water-Fluid stagnating below the Heart. (When Water-Fluid stagnates below the Heart, palpitations occur; when Yang Qi fails to circulate, cold extremities result. Cold extremities due to sweating are not treated by this formula. Various schools of thought differ on this, regarding it as a condition of Yang deficiency, hence the use of Fu Ling Gan Cao Tang.)
Treats post-Taiyang disease sweating, where the patient experiences palpitations below the umbilicus and a sensation that Ben Tun (Rushing Pig) syndrome is about to manifest.
Ling Gui Gan Cao Da Zao Tang (Poria, Cinnamon Twig, Licorice, and Jujube Decoction): Fu Ling (Poria Cocos Sclerotium) — 8 liang; Gui Zhi (Cinnamomi Ramulus) — 4 liang; Gan Cao (Glycyrrhizae Radix et Rhizoma, honey-fried) — 2 liang; Da Zao (Jujubae Fructus) — 12 pieces. Use 1 dou of Gan Lan Shui (Gentle Boiling Water). First decoct Fu Ling until the volume reduces by 2 sheng, then add the remaining herbs.
In Ling Gui Gan Cao Da Zao Tang, Gan Cao and Da Zao strengthen the Spleen and Stomach (Earth element); Fu Ling controls Water-Fluid; Gui Zhi protects Heart Yang. Fu Ling is used in a heavy dose and must be decocted first. (Herbs used in heavy doses within a formula generally require prior decoction to fully extract their efficacy or moderate their properties.) Palpitations below the umbilicus are caused by Water-Qi rushing up to harass the Heart. Gui Zhi can calm the rebellious Qi and descend the surge, making it suitable for treating palpitations.
