The Metabolic Syndrome (MS) is a cluster of cardiometabolic risk factors, which include abdominal obesity, hyperglycemia, dyslipidemia, and high blood pressure. MS is a global health problem, it represents a risk factor for the progression of cardiovascular disease, which constitute the main cause of mortality in the world and in Mexico. The current treatment involves lifestyle changes and pharmacological treatment for each of the components of MS, however, there is no single approved treatment to control all components. Celery seed (Apium graveolens L.) from the Apiaceae family contains the flavonoids apigenin and luteolin; essential oils such as d-limonene, selinene and phthalides such as 3-n-butylphthalide. Thanks to its bioactive components, celery seed has proven to be effective in treating individual MS disorders; however, most studies are in animal models and there are no clinical studies that evaluate its effectiveness on all components of the system. MS, insulin sensitivity and insulin secretion so it could appear as a new, safe and effective complementary therapy for the treatment of MS. The aim of this study is to evaluate the effect of celery seed on the components of metabolic syndrome, insulin sensitivity, and insulin secretion.
