Severe Ascites Managed by Time-Selected Therapy: A Chinese Medicine Case

A 62-year-old man with massive abdominal effusion (ascites) and severe bloating was rapidly and successfully managed using a highly specialized “time-selected” strategy: administering water-draining herbs in the morning and Spleen-tonifying herbs in the evening.

Case ID: CHC-0081

Case Summary

This case describes a 62-year-old man who developed massive ascites (abdominal effusion) over the course of a week. Presenting with severe abdominal bloating that worsened after eating, low urine output, and extreme fatigue, he sought conservative TCM treatment. The original report documented a conventional diagnosis of ascites and a TCM assessment of Drum Distension (Gu Zhang – Water Drum subtype) driven by Spleen Qi Deficiency complicated by Qi Stagnation and Dampness Obstruction. He was managed by Professor Hu Shiping using an innovative chronological approach based on the daily rhythm of the body’s Yang energy: prescribing an aggressive water-draining decoction in the morning and a restorative Spleen-tonifying decoction in the evening, completely resolving the ascites in just six days.

Patient Presentation

• Patient: 62-year-old male (Surname: Pang).
• Main Complaint: Severe abdominal bloating for 1 week.
• History: The patient sought initial consultation on March 13, 2023. One week prior, without any obvious trigger, he developed significant abdominal distension. An abdominal ultrasound at another facility revealed a massive accumulation of fluid in the abdominal cavity (ascites). Seeking TCM therapy, he presented to the outpatient clinic.
• Associated Symptoms: His spirit was fatigued, and his complexion was dull and dark. The abdominal bloating was severe and worsened noticeably after eating, accompanied by a visibly increased abdominal girth. He had no acute abdominal pain. His appetite was poor, and his urine output was minimal (oliguria). He had one bowel movement a day with no black stools.
• Physical Exam: Mild edema was present in both lower limbs.

Examination and Diagnosis

• Conventional Diagnosis: Ascites (Abdominal Effusion).
• TCM Tongue and Pulse: The tongue body was dark red (舌暗红) with a white coating. The pulse was stringy and slippery (脉弦滑).

TCM Assessment

The original practitioner interpreted the presentation as Drum Distension (Water Drum subtype) driven by Qi Stagnation and Dampness Obstruction with Spleen Qi Deficiency (鼓胀-水鼓：气滞湿阻兼脾气亏虚).

According to the holistic principles of Chinese Medicine, “Drum Distension” describes an abdomen swollen taut like a drum, correlating to modern conditions like cirrhotic ascites. The pathogenesis involves deep damage to the Liver, Spleen, and Kidneys. When the Spleen fails to transport fluids and the Liver Qi stagnates, water and blood stasis accumulate in the abdominal cavity.

This condition is a classic example of “root deficiency and branch excess” (本虚标实). The patient’s underlying Spleen Qi was severely deficient (causing the fatigue, poor appetite, and dull complexion), but the immediate, life-threatening “branch” was the massive accumulation of pathological water (causing the tight bloating, low urine, dark red tongue, and slippery pulse).

Treatment Approach

The primary treatment principle was to move Qi and drain dampness, while tonifying Qi and strengthening the Spleen (行气利湿，补气健脾).

Because the disease involves both severe weakness and severe fluid excess, a standard unified formula often fails: if it attacks the water too hard, it destroys the patient’s remaining energy; if it tonifies too much, it worsens the bloating. Professor Hu utilized a “Time-Selected Therapy” (择时治疗)—splitting the treatment into a morning “attack” formula and an evening “tonifying” formula to match the body’s natural circadian rhythm.

Interventions and Herbal Formulas

• Morning Formula (Attacking/Draining Phase): A 17-herb heavy decoction based on Zhongman Fenxiao Wan (Separate and Reduce Central Fullness Pill) to aggressively drain the fluid.
  • Moving Qi and Relieving Bloating: Da Fu Pi (Areca Peel, 15g), Zhi Shi (Immature Bitter Orange, 15g), Hou Po (Magnolia Bark, 15g), and Chen Pi (Tangerine Peel, 15g).
  • Draining Water and Reducing Edema: Fang Ji (30g), Ze Xie (Alisma, 30g), Zhu Ling (Polyporus, 30g), Che Qian Zi (Plantago Seed, 15g), and Sang Bai Pi (Mulberry Bark, 20g) forcefully open the water pathways to flush the ascites out through the urine.
  • Supporting Qi and Moving Blood: Huang Qi (Astragalus, 30g) and Gui Zhi (Cinnamon Twig, 15g) boost Yang to help vaporize the water. Dan Shen (Salvia, 30g) moves blood. Bai Zhu (15g), Bai Shao (30g), Fu Ling (30g), Mai Ya (30g), and Zhi Gan Cao (10g) protect the Spleen and stomach.
  • Administration: 3 doses. Half a dose taken daily, water decocted, taken warm after breakfast.
• Evening Formula (Tonifying/Restoring Phase): An 11-herb restorative decoction based on Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction) and Shenling Baizhu San.
  • Tonifying Spleen and Qi: Huang Qi (30g), Dang Shen (Codonopsis, 30g), Shan Yao (Chinese Yam, 20g), Bai Zhu (15g), Bai Bian Dou (White Hyacinth Bean, 30g), and Zhi Gan Cao (5g) heavily rebuild the exhausted Spleen.
  • Gently Leaching Dampness: Fu Ling (30g), Ze Xie (30g), and Chi Xiao Dou (Adzuki Bean, 30g) gently maintain fluid metabolism overnight without causing harsh fluid loss.
  • Nourishing Yin/Liver: Gou Qi Zi (Goji Berry, 20g) and Bai Shao (White Peony, 30g) nourish Yin and soften the Liver to ensure the damp-draining herbs do not dry out the body’s essential fluids.
  • Administration: 3 doses. Half a dose taken daily, water decocted, taken warm after dinner.

Follow-Up

• Second Visit (March 19, 2023 – Just 6 Days Later): A follow-up abdominal ultrasound revealed that the massive abdominal effusion (ascites) had completely disappeared. The patient reported that the abdominal bloating was vastly reduced, his appetite had returned, and the edema in his lower limbs was gone. His mental state had significantly improved, and both urination and bowel movements were completely normal.

Why This Case Is Interesting (Clinical Reasoning)

The notable feature of this case is Professor Hu’s brilliant application of chronobiology (Time-Selected Therapy) according to classical Huangdi Neijing (Inner Canon of the Yellow Emperor) principles.

The Su Wen states: “Yang Qi governs the exterior during the day. At dawn, human Qi arises; at midday, Yang Qi is robust; at dusk, Yang Qi becomes deficient and the Qi gates close.”

Professor Hu recognized that treating massive ascites requires heavy, draining “attacking” herbs. If given at night, these herbs would trigger severe diarrhea and urination, destroying the patient’s sleep and severely damaging their restorative nighttime Yang. By administering the draining formula in the morning—when the body’s natural Yang energy is surging and strong enough to withstand the “attack”—the fluid is aggressively expelled. Then, by giving a soothing, Spleen-tonifying formula in the evening—when the body’s Yang is retreating and needs nourishment—the Righteous Qi is repaired overnight. This “morning attack, evening tonification” (早攻晚补) synergy allowed the practitioner to clear a life-threatening massive ascites in under a week without exhausting the 62-year-old patient.
