About this study

Official title: Synergistic Effects of Sesame Oil, Extra Virgin Olive Oil, Psyllium Extract, and Dandelion Extract on Cholesterol Gallstone Dissolution: An In Vitro Comparative Study Against Rowachol®

Objective:

This study aims to evaluate the effectiveness of a natural mixture (sesame oil, extra virgin olive oil, psyllium extract, and dandelion extract) in dissolving cholesterol gallstones compared to the standard medication, Rowachol®.

Methods:

In laboratory experiments, 70 cholesterol gallstones obtained from 55 patients were divided into seven groups. Each group was treated with different combinations of the natural ingredients or Rowachol®. The stones were monitored for 144 hours to measure dissolution rate and cholesterol release.

    Measurement Tool: GC-MS (fatty acids), HPLC (plant extracts) Unit of Measure: mg/mL

    Measured: Baseline (T0)

  2. Synergistic Interaction Efficacy

    Comparative analysis of dissolution rates and cholesterol release between combined and individual treatments.

    Measurement Tool: Ohaus Balance + Cholestech LX-20 Unit of Measure: %, mg

    Measured: 144 hours (T3)

  3. Correlation: Compounds vs. Outcomes

    Pearson correlation coefficients between bioactive compound concentrations and dissolution metrics.

    Measurement Tool: Statistical analysis (SPSS v26) Unit of Measure: r-value (unitless)

    Measured: 144 hours (T3)

  4. Predictive Factors of Dissolution

    Multiple regression analysis identifying key predictors (e.g., oleic acid, taraxacin) of efficacy.

    Measurement Tool: Statistical analysis (SPSS v26) Unit of Measure: β-coefficient

    Measured: 144 hours (T3)

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Gallstone Dissolution Rate (time frame: 48-hours, 96-hours, 144 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06972134, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
