简要总结
The purpose of this randomized , double -blind clinical trial is to evaluate the efficacy and safety of a daily administration of Nitraria retusa extract in overweight and obese participants, during 10 days.
详细描述
Medicinal plants are widely used for their accessibility, safety and effectiveness and may be an excellent alternative strategy for developing future drugs with minor adverse effects. Several studies concerning the potential of bioactive components in plants and food products and their link to many diseases including, diabetes, cardiovascular disease and obesity.
Nitraria retusa is a salt-tolerant plant that belongs to the Nitrariaceae family. It is particularly distributed in Asia, China, North Africa, Russia and Europe.It grows in the southern part of Tunisia and it is locally known as Ghardaq. The leaves serve as supplement for the tea and are used as poultice. Fresh leaves of Nitraria retusa have been used in traditional medicine in case of poisoning, upset stomach, ulcers, gastritis, enteritis, heartburn, colitis, and colonic abdominal pain.
Moreover, anticancer, antioxidant, antiviral and antimicrobial activities of N. retusa have been reported .Several reports evinced that the leaf of Nitraria retusa contains high amounts of tannins, alkaloids, steroids and flavonoids, which could be responsible for its beneficial effects . Previous studies have demonstrated the effect of Nitraria retusa extract in obese mice against high fat diet through lowering glucose and triglycerides and the enhancement of the lipid metabolism in liver.
The purpose of this study was to evaluate the efficacy and safety of short daily administration of Nitraria retusa extract in lipid profile in overweight and obese patients, during 10 days.
This study will be carried out in 2 departments: the laboratory of biophysics of the Faculty of Medicine of Sousse and Endocrinology and diabetology of CHU Farhat Hached Sousse ,Tunisia. At day 0 and day 10 all the population will benifit of biological assessment which include:
