About this study
The study aims to evaluate the effect of ginger supplementation on inflammatory cytokines and markers of oxidative stress in patients with Coronary Artery Disease (CAD). A longitudinal double-blind randomized clinical trial will be carried out, involving CAD participants for two months.
Read the detailed description
Ginger (Zingiber officinale Roscoe) contains phenolic compounds, such as gingerols, shogaols, and zingiberene, recognized for their antioxidant and anti-inflammatory properties, and may act as an adjuvant strategy in the prevention and management of CAD. However, there are no studies in CAD patients evaluating these data.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GingerDietary supplement
Also called ginger extract
Participants will receive 2 capsules per day, providing the ginger extract daily, at a dosage of 500mg.
PlaceboDietary supplement
The placebo group will receive the same amount of 500mg placebo, at the same time, containing corn starch.
| Study group | Role | What they receive |
|---|---|---|
| Ginger Group | Experimental | Participants will receive 2 capsules per day, providing the ginger extract daily, at a dosage of 500mg. Receives: Dietary Supplement: Ginger |
| Placebo Group | Placebo comparator | The placebo group will receive the same amount of 500mg placebo, at the same time, containing corn starch. Receives: Dietary Supplement: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change of inflammatory status in the participants
Get blood samples to evaluate the supplementation effects in inflammatory biomarkers: interleukin 6 (IL-6), tumor necrosis factor-alpha (TNF-alpha), C-reactive protein (CRP).
Measured: Baseline and 8 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Ginger in people with Coronary Artery Disease (CAD) and Oxidative Stress, run by Universidade Federal Fluminense at 1 site in Brazil.

The record says: opening soon, as of the sponsor's last update on 19 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
Contact Denise Mafra (+5521985683003, dmafra30@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change of inflammatory status in the participants (time frame: Baseline and 8 weeks). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 May 2026.
