Metabolic syndrome consists of a group of risk factors characterized by abdominal obesity, hypertension, atherogenic dyslipidemia, hyperglycemia, and prothrombotic and proinflammatory conditions. Raw garlic homogenate has been reported to reduce serum lipid levels in animal model; however, no precise studies have been performed to evaluate the effect of raw crushed garlic (Allium sativum L.) on components of metabolic syndrome. Therefore, the present study was designed to investigate the effect of raw crushed garlic on components of metabolic syndrome. A total of 40 metabolic syndrome patients were randomly selected from the diabetic center of SP Medical College, Bikaner, Rajasthan, India. They underwent treatment with 100 mg/kg body weight raw crushed garlic 2 times a day with standard diet for 4 weeks; their anthropometric and serum biochemical variables were measured at both the beginning and the end of the study. Statistical analysis was performed using IBM SPSS version 20, and Student's paired "t" test was used to compare variables before and after treatment with garlic preparation. Raw crushed garlic significantly reduced components of metabolic syndrome including waist circumference (p < .05), systolic and diastolic blood pressure (p < .001), triglycerides (p < .01), fasting blood glucose (p < .0001) and significantly increased serum high-density lipoprotein cholesterol (p < .0001). There was no significant difference found in body mass index (p > .05) of patients with metabolic syndrome after consumption of raw crushed garlic for 4 weeks. Raw crushed garlic has beneficial effects on components of metabolic syndrome; therefore, it can be used as an accompanying remedy for prevention and treatment of patients with metabolic syndrome.
