- Subjects are informed and voluntarily sign the informed consent form.
Exclusion Criteria:
- Patients with severe cardiovascular, respiratory, liver, kidney, or other major organ diseases, diabetes, tumors, hematopoietic system disorders, nervous system diseases, or psychiatric disorders;
- Patients with other organic digestive system diseases (e.g., peptic ulcer) or systemic diseases affecting gastrointestinal motility (e.g., hyperthyroidism, diabetes mellitus);
- Patients currently using or requiring continuous use of medications that may affect gastrointestinal function (e.g., antidiarrheals, antidepressants, anxiolytics, intestinal microbiota regulators, antibiotics, etc.);
- Patients who have taken antibiotics, steroids or other hormones, herbal preparations (including oral and intravenous), microecological preparations, or probiotics (such as yogurt) within the past 1 week;

Lasso di tempo |
|---|---|---|
|
Irritable Bowel Syndrome Severity Scoring System scale
Lasso di tempo: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
This scale is an internationally recognized assessment tool for IBS symptom severity, with a total score ranging from 0 to 500.
Lower scores indicate milder symptoms.
|
before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment

|
Biomarker
Lasso di tempo: before treatment, after 4 weeks of treatment
|
Measure the levels of biomarkers such as IL-1β, IFN-γ, IL-6, TNF-α, diamine oxidase, D-lactic acid, and endotoxin to explore the mechanism of action.
|
before treatment, after 4 weeks of treatment
|
|
Evaluation of the efficacy of Chinese medicine evidence
Lasso di tempo: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
A quantitative scale formulated based on the Guiding Principles for Clinical Research of New Chinese Medicines and the diagnostic criteria for cold-dampness encumbering the spleen pattern, with graded scoring for primary and secondary symptoms.
Lower scores indicate milder syndromes.
|
before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
|
Patient-Reported Outcome scale
Lasso di tempo: before treatment, after 4 weeks of treatment
|
Assesses patients' self-perceived severity of core symptoms such as abdominal discomfort and bloating.
|
before treatment, after 4 weeks of treatment
|
|
Irritable Bowel Syndrome Quality of Life scale
Lasso di tempo: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
Assesses the quality of life of patients with IBS.
|
before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
|
Number of Participants with Treatment-Emergent Adverse Events (TEAEs)
Lasso di tempo: Baseline (before treatment) to Week 4
|
Treatment-emergent adverse events (TEAEs) will be assessed throughout the study period based on spontaneous subject reports, physical examinations, and investigator observations.
Incidence, severity (graded according to CTCAE v5.0), and relationship to study treatment will be recorded.
The unit of measure for this outcome is the count of participants experiencing at least one TEAE.
|
Baseline (before treatment) to Week 4
|
|
Number of Participants with Clinically Significant Abnormalities in Safety Assessments
Lasso di tempo: Baseline (before treatment) to Week 4
|
Safety assessments include vital signs (temperature, respiratory rate, heart rate, and blood pressure), clinical laboratory tests (hematology, blood biochemistry, urinalysis, and stool examination), and 12-lead electrocardiography (ECG).
The number of participants with at least one clinically significant abnormal finding according to protocol-defined clinical significance criteria will be reported.
The unit of measure for this outcome is the count of participants; participants with multiple abnormal findings will be counted only once for this measure.
|
Baseline (before treatment) to Week 4
|
|
Bristol Stool Form scale
Lasso di tempo: before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
|
Assesses stool form, classified into types 1 to 7. The mean daily BSFS score recorded on diary cards during the treatment period, and the typical BSFS type at each visit time point will be recorded.
|
before treatment, after 4 weeks of treatment, and 12 weeks after the end of treatment
