Study summary

The metabolic syndrome is associated with increased risk of cardiovascular disease and diabetes mellitus. The age-adjusted prevalence of the metabolic syndrome in the United States is 34% for men and 35% for women. Emerging alternative medicine worldwide led investigators to evaluate the efficacy of Crocus sativus (Saffron) and Berberis Vulgaris (barberry fruit) in treatment of metabolic syndrome. Serum total cholesterol, serum LDL cholesterol, serum HDL cholesterol, serum triglyceride, Fasting Blood Sugar and hematocrit measured before and after 45 days of treatment.

Read the detailed description

In a randomized, placebo controlled, single-blind , efficacy trial with three treatment arms the investigators randomly assigned 105 patients with metabolic syndrome to receive barberry juice, saffron juice or placebo tablet.

The aim was to evaluate the efficacy of Crocus sativus (Saffron) and Berberis Vulgaris (barberry fruit) in treatment of metabolic syndrome. The metabolic syndrome (syndrome X, insulin resistance syndrome) consists of a constellation of metabolic abnormalities that confer increased risk of cardiovascular disease (CVD) and diabetes mellitus (DM). The major features of the metabolic syndrome include central obesity hypertriglyceridemia, low HDL cholesterol, hyperglycemia, and hypertension. Based on data from the National Health and Nutrition Examination Survey (NHANES) III, the age-adjusted prevalence of the metabolic syndrome in the United States is 34% for men and 35% for Women. Review of literature revealed anti-inflammatory, radical-scavenging, antioxidant, cytoprotective, beneficial cardiovascular and neural system effects for saffron, potential use for treatment of hypertension, tachycardia and some neuronal disorders, such as epilepsy and convulsion, antihypertensive and vasodilatory activities. Barberry has promising and selective anti-cancer activities, beneficial effects in atherosclerosis, arthritis, coronary heart disease and hepatitis, hypotensive property and to promote immunity, prevention of insulin resistance and related diseases, neuroprotective, hypolipidemic and antioxidant properties for saffron in animal models.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 21, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
