A Single-center, Randomized, Double-blind, Placebo-controlled, Intervention Clinical Trial to Evaluate the Efficacy and Safety of "KoreaGinseng F Max" on Blood Circulation Improvement in Adults With Poor Peripheral Blood Flow
This is a single-center, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of a white ginseng extract (KoreaGinseng F Max) for improving blood circulation in adults with poor peripheral blood flow.
A total of 100 adults aged 20 to under 65 years with platelet aggregation above 55% will be enrolled and randomly assigned in a 1:1 ratio to receive either the white ginseng extract or a matching placebo for 8 weeks. Each participant takes 3 tablets after breakfast and 3 tablets after dinner (6 tablets per day).
The main goal is to measure the change in ADP-induced platelet aggregation from baseline (Visit 2) to the end of treatment (Visit 4, Week 8). The study also assesses effects on coagulation measures, blood lipids, serotonin, blood pressure, white blood cell count, and overall safety.

Descrição detalhada
Study design: Single-center, randomized, double-blind, placebo-controlled, parallel-group interventional trial.
Population: Men or women aged ≥20 and <65 years requiring improvement of blood circulation, with ADP- and collagen-induced platelet aggregation above 55%, who provide written informed consent.
Intervention: Participants are randomized 1:1 to the test product (white ginseng extract, KoreaGinseng F Max) or a matching placebo control. Dosing is 3 tablets after breakfast and 3 tablets after dinner (6 tablets/day) for 8 weeks, taken orally.
Visit schedule: Screening (Visit 1, Week -2 to 0); randomization/baseline (Visit 2, Week 0); interim visit (Visit 3, Week 4 ±5 days); end-of-treatment (Visit 4, Week 8 ±5 days); plus a supplementary visit if needed.
Primary endpoint: Change in ADP-induced platelet aggregation from baseline (Visit 2) to Visit 4.
Secondary endpoints: Percent change in ADP-induced platelet aggregation; change and percent change in prothrombin time and activated partial thromboplastin time; change in serum lipids (total cholesterol, HDL-C, LDL-C, triglycerides); change in serotonin; change in systolic and diastolic blood pressure; and - all from baseline to Visit 4.
Sample size: 100 participants (2 groups); approximately 50 evaluable per group, accounting for an ~8% dropout rate.
