此症乃气虚作肿，似水而非水也，但按之不如泥耳。必先从脚面上肿起，后渐肿至身上，于是头面皆肿者有之，
此之谓之气臌。宜于健脾行气之中，加利水之品。若以水臌治之，是速之死也。方用∶
白术（一两） 茯苓（一两） 人参（一钱） 甘草（一分） 山药（五钱） 肉桂（一分） 萝卜子（一钱）
枳壳（五分） 薏仁（一两） 车前子（一钱） 神曲（一钱）
水煎服。
初服若觉有碍，久之自有大功，不过三十剂而痊愈矣。忌食盐三月，秋石亦忌。
此症小腹作痛，四肢浮肿而未甚，面色红而有白点，如虫食之状，眼下无卧蚕微肿之形，是之谓之血臌，方用
消虫神奇丹∶
雷丸（三钱） 当归（一两） 鳖甲（一两） 地栗粉（一两） 神曲（三钱） 茯苓（三钱） 车前子（五钱）
白矾（三钱）
水煎服。
一剂下虫无数，二剂虫尽出而臌消，不必三剂。但病好后必须用六君子汤去甘草调理。
此症或因跌闪而瘀血不散，或因忧郁而结血不行，或因风邪而蓄血不散，留在腹中，致成血臌。饮食入胃，不
变精血，反去助邪，久则胀，胀则成臌矣。倘以治水法逐之，而症非水，徒伤元气。倘以治气法治之，而症非气，
徒增饱满。方用逐瘀荡秽汤∶
水蛭（炒萸为末，三钱） 当归（二两） 雷丸（三钱） 白芍（三钱） 红花（三钱） 枳壳（三钱）
牛膝（三钱） 桃仁（四十粒）
水煎服。
一剂血尽而愈，切勿与二剂，当改用四物汤调理。于补血内加白术、茯苓、人参，补元气而利水，自然痊愈，
否则恐成干枯之症。
辨血臌，惟腹胀如臌，而四肢手足并无胀意也。
This condition is swelling caused by Qi deficiency; it resembles edema but is not water retention. Upon palpation, it does not pit like mud. It typically begins with swelling on the dorsum of the feet and gradually spreads to the entire body, sometimes involving the head and face. This is termed "Qi Distension" (abdominal distension due to Qi stagnation). Treatment should focus on invigorating the Spleen and promoting Qi circulation, while adding herbs that promote diuresis. If treated as "Water Distension" (abdominal distension due to fluid retention), it will hasten death. The prescription is as follows:
Bai Zhu (Atractylodis Rhizoma, 1 liang), Fu Ling (Poria, 1 liang), Ren Shen (Ginseng Radix, 1 qian), Gan Cao (Licorice Root, 1 fen), Shan Yao (Dioscoreae Rhizoma, 5 qian), Rou Gui (Cinnamomi Cortex, 1 fen), Luo Bo Zi (Raphani Semen, 1 qian), Zhi Qiao (Aurantii Fructus, 5 fen), Yi Yi Ren (Coicis Semen, 1 liang), Che Qian Zi (Plantaginis Semen, 1 qian), Shen Qu (Massa Medicata Fermentata, 1 qian).
Decoct in water and take orally.
Initially, one may feel some discomfort upon taking the medicine, but significant efficacy will manifest over time. Recovery can be expected after approximately thirty doses. Salt intake must be avoided for three months, and Qiu Shi (Human Urine Stone) should also be avoided.
This condition presents with pain in the lower abdomen, mild edema of the four limbs, a red complexion with white spots resembling insect bites, and no slight swelling under the eyes (resembling a silkworm lying down). This is termed "Blood Distension" (abdominal distension due to blood stasis or parasites). The prescription is Xiao Chong Shen Qi Dan (Miraculous Powder for Eliminating Parasites):
Lei Wan (Omphalophaga Melaena, 3 qian), Dang Gui (Angelicae Sinensis Radix, 1 liang), Bie Jia (Testudinis et Carapacis Scutellum, 1 liang), Di Li Fen (Dioscoreae Hypoglaucae Rhizoma, 1 liang), Shen Qu (Massa Medicata Fermentata, 3 qian), Fu Ling (Poria, 3 qian), Che Qian Zi (Plantaginis Semen, 5 qian), Bai Fan (Alumen, 3 qian).
Decoct in water and take orally.
After one dose, numerous parasites are expelled; after two doses, all parasites are eliminated and the distension subsides, so a third dose is unnecessary. However, after recovery, the patient must be regulated using Liu Jun Zi Tang (Six Gentlemen Decoction) with Gan Cao removed.
This condition may arise from unresolved blood stasis due to falls or sprains, stagnant blood due to melancholy, or accumulated blood due to wind pathogens remaining in the abdomen, leading to Blood Distension. Food entering the stomach fails to transform into essence and blood but instead aids the pathogenic factors. Over time, this causes bloating, which eventually develops into distension. If treated with methods for draining water, since the pathology is not water, it will merely injure the Yuan Qi (Original Qi). If treated with methods for moving Qi, since the pathology is not Qi stagnation, it will merely increase fullness. The prescription is Zhu Yu Dang Hui Tang (Decoction for Expelling Stasis and Purging Filth):
Shui Zhi (Hirudo, stir-fried with Wu Zhu Yu [Evodiae Fructus] into powder, 3 qian), Dang Gui (Angelicae Sinensis Radix, 2 liang), Lei Wan (Omphalophaga Melaena, 3 qian), Bai Shao (Paeoniae Radix Alba, 3 qian), Hong Hua (Carthami Flos, 3 qian), Zhi Qiao (Aurantii Fructus, 3 qian), Niu Xi (Achyranthis Bidentatae Radix, 3 qian), Tao Ren (Persicae Semen, 40 grains).
Decoct in water and take orally.
After one dose, the blood stasis is cleared and the patient recovers. Do not administer a second dose. Instead, switch to Si Wu Tang (Four Substances Decoction) for regulation. Add Bai Zhu (Atractylodis Rhizoma), Fu Ling (Poria), and Ren Shen (Ginseng Radix) to the blood-nourishing formula to tonify Yuan Qi and promote diuresis, ensuring natural recovery. Otherwise, there is a risk of developing a dry, emaciated condition.
To distinguish Blood Distension: the abdomen is distended like a drum, but the four limbs and hands/feet show no signs of swelling.
