Study on the Application of Chinese Herbal Bath in Cancer Fatigue of Chemotherapy Patients with Colorectal Malignancy ()
1. Introduction
Colorectal cancer ranks as the third most common malignant tumor globally, with both incidence and mortality rates among the highest in malignancies [1]. Approximately 70% of patients require chemotherapy, yet the cytotoxic effects of these drugs often lead to various adverse reactions. Cancer-related fatigue (CRF), occurring in 75% to 96% of cases [2], manifests as persistent, subjective exhaustion disproportionate to physical activity levels that persists despite rest. This condition significantly compromises patients’ quality of life, treatment adherence, and prognosis [3].
Current clinical management of chronic fatigue syndrome (CRF) primarily involves central nervous system stimulants and antidepressants, though these medications demonstrate limited efficacy with notable side effects including insomnia and anxiety [4]. Traditional Chinese Medicine (TCM) classifies CRF under the “deficiency syndrome” and “fatigue” categories, identifying chemotherapy drugs as “medication toxins” that disrupt qi-blood balance and yin-yang harmony. This leads to spleen-kidney deficiency, blood qi insufficiency, and meridian blockage, creating a pathological pattern characterized by the interplay of deficiency and stasis [5]. As a cornerstone of TCM external therapies, herbal steam baths achieve therapeutic effects through combined transdermal absorption and thermal stimulation. These methods effectively warm meridians, enhance qi circulation, activate blood flow, and strengthen the body’s defenses against pathogens, demonstrating particular efficacy in managing chronic fatigue symptoms [6] [7].
At present, there are few systematic studies on the effect of Chinese herbal soaking on CRF in chemotherapy patients with colorectal cancer. This study adopted Chinese herbal soaking to treat chemotherapy patients with colorectal cancer, and observed its effects on CRF, TCM syndrome and quality of life, so as to provide a basis for providing safe and effective TCM nursing plan for clinical practice.
2. Clinical Data
2.1. General Information
This study recruited 200 chemotherapy patients with colorectal malignancies through convenience sampling in the oncology department of a tertiary hospital in Jingzhou City from January to December 2024. After screening and excluding 80 non-compliant cases, 120 eligible participants were enrolled. Patients were randomly assigned to the observation group (60 cases) and control group (60 cases) using a 1:1 ratio through a random number table method. No statistically significant differences were observed between the two groups in terms of gender, age, tumor stage, chemotherapy regimen, or other baseline characteristics (P > 0.05; Table 1). The study was approved by the hospital’s ethics committee (Approval No.: LL2024104), and all participants provided informed consent.

3. Methodology
3.1. Treatment Methods
Both patient groups received standardized chemotherapy for colorectal cancer: Protocol 1) Capecitabine 1000 mg/m2, administered orally twice daily from days 1 to 14; Oxaliplatin intravenous infusion on day 1, with each cycle lasting 3 weeks. Protocol 2) Calcium leucovorin intravenous infusion from days 1 to 5; Fluorouracil intravenous infusion on days 1 to 5. Protocol 3) Oxaliplatin 130 mg/m2 intravenous infusion on day 1, with each cycle lasting 4 weeks.
3.1.1. Control Group
Routine chemotherapy nursing care included: 1) Health education: Instruction on self-care precautions and CRF management techniques; 2) Dietary guidance: Encouraging high-protein and vitamin-rich diets; 3) Activity guidance: Moderate exercise tailored to physical condition; 4) Psychological counseling: Listening to patients’ concerns and alleviating anxiety. The intervention lasted 4 weeks.
3.1.2. Observation Group
The control group was supplemented with a traditional Chinese herbal powder pack. 1) Herbal formula: Astragalus 30 g, Codonopsis 20 g, Atractylodes 15 g, Poria 15 g, Angelica 15 g, Chuanxiong 15 g, Spatholobus Stem 30 g, Eucommia 15 g, Achyranthes Root 15 g, Carthamus Seed 10 g, Mugwort Leaf 10 g, Ginger slices 3. 2) Usage: Patients sit with their feet and lower legs (ankle to knee) immersed in 38˚ - 42˚ hot water containing the herbal pack, ensuring the liquid level covers the Sanyinjiao acupoint. Soak for 20 - 30 minutes daily starting 24 hours after chemotherapy for four weeks. Closely monitor reactions; discontinue immediately if dizziness, palpitations, or skin irritation occur. Patients maintain foot bath logs recording soaking duration (time, length, response). Responsible nurses verify logs weekly with signatures, calculating completion rate = actual completed sessions/ total required sessions × 100%.
3.2. Observation Indicators
3.2.1. Cancer-Related Fatigue Rating
The Piper Fatigue Scale (PFS) was administered at baseline, 2 weeks post-intervention, and 4 weeks post-intervention. This scale evaluates four dimensions: behavioral, emotional, sensory, and cognitive, comprising 22 items. Each item is scored on a 0 - 10 scale (0 for no fatigue to 10 for extreme fatigue). Higher total scores and dimension-specific scores indicate more severe fatigue.
3.2.2. TCM Syndrome Scoring
The scoring criteria were established in accordance with the “Guidelines for Clinical Research of New Traditional Chinese Medicine Drugs (Trial)”, evaluating four primary symptoms (fatigue, shortness of breath, reluctance to speak, and heavy limbs) and secondary symptoms (pale complexion, loss of appetite) using a 0 - 6 point scale: 0 points for none, 2 points for mild, 4 points for moderate, and 6 points for severe. Higher total scores indicate more severe symptoms. Assessments were conducted before intervention initiation and after 4 weeks of treatment.
3.2.3. Quality of Life Assessment
The European Organization for Cancer Research and Treatment Core Questionnaire for Quality of Life (EORTC QLQ-C30, version 3.0) was administered before intervention and after 4 weeks of treatment. This questionnaire evaluates five functional dimensions (physical, occupational, emotional, cognitive, and social), nine symptom dimensions, and one overall health status dimension. Higher scores in functional dimensions indicate better quality of life, while higher scores in symptom dimensions reflect more severe symptoms.
3.2.4. Safety Indicators
Adverse reactions during the intervention, including skin allergy, dizziness, palpitation, etc., were recorded and evaluated in accordance with the “Quality Management Standard for Drug Clinical Trials”.
3.3. Statistical Methods
Statistical analysis was performed using SPSS25.0 software. Quantitative data were expressed as x ± s. Intra-group comparisons employed paired t-tests, while intergroup comparisons utilized independent samples t-tests. Repeated measures data were analyzed through repeated measures ANOVA. Categorical data were presented as frequency percentages (%), with comparisons conducted using χ2 tests. Statistical significance was defined as P < 0.05.
4. Results
4.1. Ejection Status of Two Groups of Patients
The observation group experienced 1 case of mid-travel transfer and loss to follow-up, while the control group had 2 cases of voluntary withdrawal. Ultimately, 117 cases completed the study (59 in the observation group vs. 58 in the control group), with a dropout rate of 2.5%. For the 3 withdrawn patients: the lost-to-follow-up cases were treated as treatment failure, while the voluntarily withdrawn cases adopted the last observation carry-over method. Sensitivity analysis demonstrated that the results from the Intensive Treatment Set (ITT, n = 120) were consistent with those from the Per-Protocol Set (PPS, n = 117) (P > 0.05), indicating robustness of the findings.
4.2. Comparison of PFS Scores before and after Intervention
Between the Two Groups
Before intervention, there was no statistically significant difference between the two groups in PFS total score and each dimension score (P > 0.05) (Table 2).
After intervention, the total PFS score and each dimension score of the two groups were significantly lower than that before intervention (P < 0.01), and the observation group was significantly lower than that of the control group (P < 0.01) (Table 3 and Table 4).

After 4 weeks of intervention, the scores of somatic function, role function, emotional function and social function in the observation group were significantly increased compared with that before intervention (P < 0.01), and the score of fatigue symptom was significantly reduced (P < 0.01), and all indicators were significantly better than that in the control group (P < 0.01) (Table 8).
4.5. Comparison of Safety between the Two Groups
In the observation group, there was 1 case of mild skin itching (the drug was not stopped, and it was relieved after reducing the water temperature), and the incidence of adverse reactions was 1.7%; in the control group, there was no adverse reaction, and the comparison of the incidence of adverse reactions between the two groups showed no statistically significant difference (χ2 = 0.336, P = 0.562).
5. Discussion
The clinical response (CRF) in colorectal cancer patients undergoing chemotherapy is the result of multiple factors. Chemotherapy drugs directly impair bone marrow hematopoietic function, leading to anemia and decreased immune function, while also triggering neuroendocrine disorders and chronic inflammatory responses, resulting in persistent fatigue [8] [9]. Current clinical interventions for CRF primarily focus on symptomatic support with limited efficacy. Traditional Chinese medicine (TCM), however, demonstrates unique advantages in CRF management through holistic regulation. Professor Chen Jun’s team published “Exploring the Pharmacodynamic Basis and Potential Molecular Mechanisms of Topical Application of Pungent-Heat Herbal Volatile Oils Based on Network Pharmacology,” which analyzed 20 pungent herbal volatile oils using stepwise discrimination methods. The study revealed that heat-inducing volatile oils (containing high concentrations of sesquiterpenes) exhibit significantly stronger transdermal penetration effects compared to cold-natured oils like mint. Moreover, sesquiterpene components can form a “stratum corneum storage effect” that prolongs drug release duration. This “hot-natured efficacy” principle aligns closely with the selection of heat-inducing herbs such as mugwort and ginger in TCM formulas, providing chemical and pharmacodynamic evidence for the therapeutic approach of warming and unblocking meridians [10].
This study posits that chemotherapy-induced “medication toxicity” in colorectal cancer patients leads to insufficient qi-blood production and impaired circulation. The herbal formula combines Astragalus, Codonopsis, Atractylodes, and Poria to strengthen spleen function, Eucommia and Achyranthes root to tonify kidneys and lumbar strength, while Angelica, Ligusticum, Spatholobus Root, and Carthamus promote blood circulation and resolve stasis. Mugwort and ginger further warm and unblock meridians. This comprehensive approach achieves dual enhancement of spleen-kidney function and harmonizes qi-blood balance, aligning with the pathophysiological characteristics of CRF (Chronic Fatigue Syndrome).
Traditional Chinese herbal foot baths exert their effects through the following mechanisms: 1) Transdermal absorption: Astragalus polysaccharides in Astragalus membranaceus enhance immune function and inhibit inflammatory factor release [11]; Curcuma oil in Angelica sinensis improves microcirculation and promotes hematopoietic function [12]; Eucommia glycosides in Eucommia ulmoides exhibit anti-fatigue and endocrine-regulating effects . 2) Thermogenic stimulation: Medicinal solutions at around 40˚C dilate local blood vessels, improve circulation and lymphatic drainage, accelerate metabolic waste elimination, while stimulating acupoints on the sole (e.g., Yongquan and Taixi) to regulate visceral functions via meridian pathways . 3) Neurohumoral regulation: The therapeutic comfort during foot baths alleviates anxiety, stimulates neuropeptide release such as endorphins, and reduces perceived fatigue [14].
The study results demonstrated that after 4 weeks of intervention, the observed group showed significantly lower overall progression-free survival (PFS) scores and subscale ratings compared to the control group (P < 0.01), indicating that herbal infusion therapy can improve chronic fatigue syndrome (CRF) through behavioral, emotional, sensory, and cognitive dimensions. The observed group exhibited a marked reduction in TCM syndrome scores (P < 0.01), significant improvements in quality-of-life function scores, and a notable decrease in fatigue symptom scores (P < 0.01), suggesting that herbal infusion therapy may indirectly enhance patients’ quality of life by alleviating fatigue. Safety analysis revealed no significant difference in adverse reaction rates between groups, confirming the therapy’s good safety profile.
Limitations of this study: 1) The small sample size and single-center design may introduce bias; 2) No pharmacological component analysis or in-depth exploration of the mechanism of action; 3) Short follow-up duration necessitates further observation of long-term efficacy. Future studies could adopt a multicenter, large-sample approach, utilize modern molecular biology techniques to elucidate the mechanism, and optimize washing protocols (including drug concentration, temperature, and duration) to enhance therapeutic outcomes.
6. Conclusion
Chinese herbal bath can effectively relieve cancer fatigue in patients with colorectal malignant tumor chemotherapy, improve the clinical symptoms of spleen and kidney deficiency and blood stasis, improve quality of life, and has good safety, which is worth clinical application.
