(Sub-swelling, also known as Zi Qi, Zi Man, or Tai Shui)
Pregnant women often experience swelling of the face, eyes, legs, and feet, hence various names for such swellings. In essence, all these conditions arise from the insufficiency of Spleen Earth (the digestive system's transformative function) to transport and transform the dampness generated from food and fluids. This leads to obstruction within the fetus sac, impaired transformation in the Bladder, and rampant flooding of water. Consequently, Lung Qi fails to descend, resulting in panting, and urination becomes dribbling and difficult. Ancient prescriptions utilize Liyu Tang (Carp Decoction), Kuifu Tang (Abelmoschus Seeds and Poria Decoction), and Baizhu San (Atractylodes Macrocephala Powder), all of which have excellent effects. I frequently use Wupi Yin (Five Peel Decoction), treating it similarly to edema, and it is often effective. Since this is fundamentally a disorder of water metabolism, this formula is simple and easy to apply; thus, Liyu Tang is no longer repeatedly used. However, tonics like Ginseng and Atractylodes should not be administered too early, as tonification can cause blockage and stagnation. The general principle should prioritize promoting diuresis and resolving dampness. If the patient has a robust physique, or if the swelling is mild with normal urination, treatment may not be necessary, as it will resolve spontaneously after childbirth. These remarks apply to cases where there is no sensation of distension or discomfort.
Liyu Tang (Carp Decoction)
Baizhu (Atractylodis Macrocephalae Rhizoma) (4 liang)
Shengjiang (Zingiberis Recens Rhizoma) (1 liang)
Fuling (Poria) (4 liang)
Danggui (Angelicae Sinensis Radix) (2 liang)
Baishao (Paeoniae Radix Alba) (2 liang)
Li Yu (Cyprini Carpio) (one carp weighing 1 jin)
First, boil the carp in water to extract the broth, clarify it, and then decoct the herbs in this broth. Divide into five doses for administration.
Kuifu Tang (Abelmoschus Seeds and Poria Decoction)
Dongkuizi (Abelmoschi Semen) (0.5 jin, stir-fried)
Fuling (Poria) (3 liang)
Grind together into powder. Take 3 qian each time, washed down with rice soup.
Baizhu San (Atractylodes Macrocephala Powder)
Tu Chao Baizhu (Soil-stir-fried Atractylodis Macrocephalae Rhizoma) (1.5 qian)
Fuling (Poria) (1.5 qian)
Zexie (Alismatis Rhizoma) (0.8 qian)
Chenpi (Citri Reticulatae Pericarpium) (0.5 qian)
Jiang Pi (Zingiberis Pericarpium) (0.5 qian)
Dafupi (Arecae Pericarpium) (1.2 qian)
Muxiang (Aucklandiae Radix) (0.3 qian)
The original prescription does not specify dosages.
Jiawei Wupi Yin (Modified Five Peel Decoction)
Sangbaipi (Mori Cortex) (1.5 qian)
Dafupi (Arecae Pericarpium) (1.5 qian; this herb is only suitable for treating fetal swelling. It is commonly observed that patients with edema taking this herb experience worsening symptoms, so it must be used with caution.)
Fuling Pi (Poria Cum Ligno Bark) (1.5 qian)
Xinhui Pi (Citri Reticulatae Pericarpium Rubrum) (1.5 qian)
Zisugeng (Perillae Caulis) (1.5 qian)
Cheqianzi (Plantaginis Semen) (1.5 qian)
Lao Jiang Pi (Old Zingiberis Pericarpium) (0.8 qian)
Wujia Pi (Acanthopanacis Cortex) (1.5 qian)
After two or three doses, add Baizhu (Atractylodis Macrocephalae Rhizoma) and Fuling (Poria). Once the swelling has reduced by more than half, subsequently administer Liu Junzi Tang (Six Gentlemen Decoction) to tonify Spleen Qi. The diet should also be bland, as a bland flavor promotes leaching out dampness.
